Changes affecting past time stamps
|
|
|
|
America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.
|
|
|
|
Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
|
|
not 1920-01-06. The old entry was based on a misinterpretation of Shanks.
|
|
|
|
Some more zones have been turned into links, when they differed
|
|
from existing zones only for older time stamps. As usual,
|
|
these changes affect UTC offsets in pre-1970 time stamps only.
|
|
Their old contents have been moved to the 'backzone' file.
|
|
The affected zones are: Africa/Blantyre, Africa/Bujumbura,
|
|
Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi,
|
|
Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.
|
|
|
|
Changes affecting code
|
|
|
|
zdump -V and -v now output gmtoff= values on all platforms,
|
|
not merely on platforms defining TM_GMTOFF.
|
|
|
|
The tz library's localtime and mktime functions now set tzname to a value
|
|
appropriate for the requested time stamp, and zdump now uses this
|
|
on platforms not defining TM_ZONE, fixing a 2014g regression.
|
|
(Thanks to Tim Parenti for reporting the problem.)
|
|
|
|
The tz library no longer sets tzname if localtime or mktime fails.
|
|
|
|
zdump -c no longer mishandles transitions near year boundaries.
|
|
(Thanks to Tim Parenti for reporting the problem.)
|
|
|
|
An access to uninitalized data has been fixed.
|
|
(Thanks to Jörg Richter for reporting the problem.)
|
|
|
|
When THREAD_SAFE is defined, the code ports to the C11 memory model.
|
|
A memory leak has been fixed if ALL_STATE and THREAD_SAFE are defined
|
|
and two threads race to initialize data used by gmtime-like functions.
|
|
(Thanks to Andy Heninger for reporting the problems.)
|
|
|
|
Changes affecting build procedure
|
|
|
|
'make check' now checks better for properly-sorted data.
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
zdump's gmtoff=N output is now documented, and its isdst=D output
|
|
is now documented to possibly output D values other than 0 or 1.
|
|
|
|
zdump -c's treatment of years is now documented to use the
|
|
Gregorian calendar and Universal Time without leap seconds,
|
|
and its behavior at cutoff boundaries is now documented better.
|
|
(Thanks to Arthur David Olson and Tim Parenti for reporting the problems.)
|
|
|
|
Programs are now documented to use the proleptic Gregorian calendar.
|
|
(Thanks to Alan Barrett for the suggestion.)
|
|
|
|
Fractional-second GMT offsets have been documented for civil time
|
|
in 19th-century Chennai, Jakarta, and New York.
|
|

Changes affecting future time stamps
|
|
|
|
Turks & Caicos is switching from US eastern time to UTC-4 year-round,
|
|
modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00.
|
|
|
|
Changes affecting past time stamps
|
|
|
|
Time in Russia or the USSR before 1926 or so has been corrected by
|
|
a few seconds in the following zones: Asia/Irkutsk,
|
|
Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi,
|
|
Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara. For
|
|
Asia/Yekaterinburg the correction is a few minutes. (Thanks to
|
|
Vladimir Karpinsky.)
|
|
|
|
The Portuguese decree of 1911-05-26 took effect on 1912-01-01.
|
|
This affects 1911 time stamps in Africa/Bissau, Africa/Luanda,
|
|
Atlantic/Azores, and Atlantic/Madeira. Also, Lisbon's pre-1912
|
|
GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32.
|
|
(Thanks to Stephen Colebourne for pointing to the decree.)
|
|
|
|
Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.
|
|
|
|
A new file 'backzone' contains data which may appeal to
|
|
connoisseurs of old time stamps, although it is out of scope for
|
|
the tz database, is often poorly sourced, and contains some data
|
|
that is known to be incorrect. The new file is not recommended
|
|
for ordinary use and its entries are not installed by default.
|
|
(Thanks to Lester Caine for the high-quality Jersey, Guernsey, and
|
|
Isle of Man entries.)
|
|
|
|
Some more zones have been turned into links, when they differed
|
|
from existing zones only for older time stamps. As usual,
|
|
these changes affect UTC offsets in pre-1970 time stamps only.
|
|
Their old contents have been moved to the 'backzone' file.
|
|
The affected zones are: Africa/Bangui, Africa/Brazzaville,
|
|
Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda,
|
|
Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo.
|
|
|
|
Changes affecting code
|
|
|
|
Unless NETBSD_INSPIRED is defined to 0, the tz library now
|
|
supplies functions for creating and using objects that represent
|
|
time zones. The new functions are tzalloc, tzfree, localtime_rz,
|
|
mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and
|
|
time2posix_z. They are intended for performance: for example,
|
|
localtime_rz (unlike localtime_r) is trivially thread-safe without
|
|
locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired
|
|
functions, and to Alan Barrett and Jonathan Lennox for helping to
|
|
debug the change.)
|
|
|
|
zdump now builds with the tz library unless USE_LTZ is defined to 0,
|
|
This lets zdump use tz features even if the system library lacks them.
|
|
To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0
|
|
TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='.
|
|
|
|
zdump now uses localtime_rz if available, as it's significantly faster,
|
|
and it can help zdump better diagnose invalid time zone names.
|
|
Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ
|
|
defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is
|
|
not available, zdump now uses localtime_r and tzset if available,
|
|
as this is a bit cleaner and faster than plain localtime. Compile
|
|
with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system
|
|
lacks these two functions.
|
|
|
|
If THREAD_SAFE is defined to 1, the tz library is now thread-safe.
|
|
Although not needed for tz's own applications, which are single-threaded,
|
|
this supports POSIX better if the tz library is used in multithreaded apps.
|
|
|
|
Some crashes have been fixed when zdump or the tz library is given
|
|
invalid or outlandish input.
|
|
|
|
The tz library no longer mishandles leap seconds on platforms with
|
|
unsigned time_t in time zones that lack ordinary transitions after 1970.
|
|
|
|
The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not
|
|
already defined, to make it easier to configure on common platforms.
|
|
Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this.
|
|
|
|
Unless the new macro UNINIT_TRAP is defined to 1, the tz code now
|
|
assumes that reading uninitialized memory yields garbage values
|
|
but does not cause other problems such as traps.
|
|
|
|
If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now
|
|
more likely to guess right for ambiguous time stamps near
|
|
transitions where tm_isdst does not change.
|
|
|
|
If HAVE_STRFTIME_L is defined to 1, the tz library now defines
|
|
strftime_l for compatibility with recent versions of POSIX.
|
|
Only the C locale is supported, though. HAVE_STRFTIME_L defaults
|
|
to 1 on recent POSIX versions, and to 0 otherwise.
|
|
|
|
tzselect -c now uses a hybrid distance measure that works better
|
|
in Africa. (Thanks to Alan Barrett for noting the problem.)
|
|
|
|
The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used,
|
|
or when time_tz is defined.
|
|
|
|
When HAVE_UTMPX_H is set the 'date' command now builds on systems
|
|
whose <utmpx.h> file does not define WTMPX_FILE, and when setting
|
|
the date it updates the wtmpx file if _PATH_WTMPX is defined.
|
|
This affects GNU/Linux and similar systems.
|
|
|
|
For easier maintenance later, some C code has been simplified,
|
|
some lint has been removed, and the code has been tweaked so that
|
|
plain 'make' is more likely to work.
|
|
|
|
The C type 'bool' is now used for boolean values, instead of 'int'.
|
|
|
|
The long-obsolete LOCALE_HOME code has been removed.
|
|
|
|
The long-obsolete 'gtime' function has been removed.
|
|
|
|
Changes affecting build procedure
|
|
|
|
'zdump' no longer links in ialloc.o, as it's not needed.
|
|
|
|
'make check_time_t_alternatives' no longer assumes GNU diff.
|
|
|
|
Changes affecting distribution tarballs
|
|
|
|
The files checktab.awk and zoneinfo2tdf.pl are now distributed in
|
|
the tzdata tarball instead of the tzcode tarball, since they help
|
|
maintain the data. The NEWS and Theory files are now also
|
|
distributed in the tzdata tarball, as they're relevant for data.
|
|
(Thanks to Alan Barrett for pointing this out.) Also, the
|
|
leapseconds.awk file is no longer distributed in the tzcode
|
|
tarball, since it belongs in the tzdata tarball (where 2014f
|
|
inadvertently also distributed it).
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for
|
|
suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms
|
|
for debugging it.)
|
|
|
|
The man pages have been updated to use function prototypes,
|
|
to document thread-safe variants like localtime_r, and to document
|
|
the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and
|
|
mktime_z.
|
|
|
|
The fields in Link lines have been renamed to be more descriptive
|
|
and more like the parameters of 'ln'. LINK-FROM has become TARGET,
|
|
and LINK-TO has become LINK-NAME.
|
|
|
|
tz-link.htm mentions the IETF's tzdist working group; Windows
|
|
Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab.
|
|
|
|
Some broken URLs have been fixed in the commentary. (Thanks to
|
|
Lester Caine.)
|
|
|
|
Commentary about Philippines DST has been updated, and commentary
|
|
on pre-1970 time in India has been added.
|
|
|
|

Changes affecting future time stamps
|
|
|
|
Russia will subtract an hour from most of its time zones on 2014-10-26
|
|
at 02:00 local time. (Thanks to Alexander Krivenyshev.)
|
|
There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky
|
|
Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug
|
|
(Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast
|
|
(Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic
|
|
(Europe/Samara) are not changing their clocks. The changed zones are
|
|
Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd,
|
|
Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk,
|
|
Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga,
|
|
Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours
|
|
subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected,
|
|
but not its UTC offset. Two zones are added: Asia/Chita (split
|
|
from Asia/Yakutsk, and also with two hours subtracted) and
|
|
Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour
|
|
subtracted). (Thanks to Tim Parenti for much of the above.)
|
|
|
|
Changes affecting time zone abbreviations
|
|
|
|
Australian eastern time zone abbreviations are now AEST/AEDT not EST,
|
|
and similarly for the other Australian zones. That is, for eastern
|
|
standard and daylight saving time the abbreviations are AEST and AEDT
|
|
instead of the former EST for both; similarly, ACST/ACDT, ACWST/ACWDT,
|
|
and AWST/AWDT are now used instead of the former CST, CWST, and WST.
|
|
This change does not affect UTC offsets, only time zone abbreviations.
|
|
(Thanks to Rich Tibbett and many others.)
|
|
|
|
Asia/Novokuznetsk shifts from NOVT to KRAT (remaining on UTC+7)
|
|
effective 2014-10-26 at 02:00 local time.
|
|
|
|
The time zone abbreviation for Xinjiang Time (observed in Ürümqi)
|
|
has been changed from URUT to XJT. (Thanks to Luther Ma.)
|
|
|
|
Prefer MSK/MSD for Moscow time in Russia, even in other cities.
|
|
Similarly, prefer EET/EEST for eastern European time in Russia.
|
|
|
|
Change time zone abbreviations in (western) Samoa to use "ST" and
|
|
"DT" suffixes, as this is more likely to match common practice.
|
|
Prefix "W" to (western) Samoa time when its standard-time offset
|
|
disagrees with that of American Samoa.
|
|
|
|
America/Metlakatla now uses PST, not MeST, to abbreviate its time zone.
|
|
|
|
Time zone abbreviations have been updated for Japan's two time
|
|
zones used 1896-1937. JWST now stands for Western Standard
|
|
Time, and JCST for Central Standard Time (formerly this was CJT).
|
|
These abbreviations are now used for time in Korea, Taiwan,
|
|
and Sakhalin while controlled by Japan.
|
|
|
|
Changes affecting past time stamps
|
|
|
|
China's five zones have been simplified to two, since the post-1970
|
|
differences in the other three seem to have been imaginary. The
|
|
zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been
|
|
removed; backwards-compatibility links still work, albeit with
|
|
different behaviors for time stamps before May 1980. Asia/Urumqi's
|
|
1980 transition to UTC+8 has been removed, so that it is now at
|
|
UTC+6 and not UTC+8. (Thanks to Luther Ma and to Alois Treindl;
|
|
Treindl sent helpful translations of two papers by Guo Qingsheng.)
|
|
|
|
Some zones have been turned into links, when they differed from existing
|
|
zones only for older UTC offsets where data entries were likely invented.
|
|
These changes affect UTC offsets in pre-1970 time stamps only. This is
|
|
similar to the change in release 2013e, except this time for western
|
|
Africa. The affected zones are: Africa/Bamako, Africa/Banjul,
|
|
Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome,
|
|
Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and
|
|
Atlantic/St_Helena. This also affects the backwards-compatibility
|
|
link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne,
|
|
Tim Parenti, and David Patte for reporting problems in earlier
|
|
versions of this change.)
|
|
|
|
Asia/Shanghai's pre-standard-time UT offset has been changed from
|
|
8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its
|
|
transition to standard time has been changed from 1928 to 1901.
|
|
|
|
Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01,
|
|
then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945.
|
|
In 1946 it observed DST from 05-15 through 09-30; in 1947
|
|
from 04-15 through 10-31; and in 1979 from 07-01 through 09-30.
|
|
(Thanks to Yu-Cheng Chuang.)
|
|
|
|
Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950.
|
|
|
|
Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not
|
|
10-03 at 00:00. (Thanks to Konstantin Hyppönen.)
|
|
|
|
Pacific/Pago_Pago has been changed from UTC-11:30 to UTC-11 for the period
|
|
from 1911 to 1950.
|
|
|
|
Pacific/Chatham has been changed to New Zealand standard time plus
|
|
45 minutes for the period before 1957, reflecting a 1956 remark in
|
|
the New Zealand parliament.
|
|
|
|
Europe/Budapest has several pre-1946 corrections: in 1918 the transition
|
|
out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in
|
|
1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08
|
|
not 04-06 at 02:00; and there was no DST in 1920.
|
|
|
|
Africa/Accra is now assumed to have observed DST from 1920 through 1935.
|
|
|
|
Time in Russia before 1927 or so has been corrected by a few seconds in
|
|
the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi,
|
|
Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and
|
|
Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0
|
|
point. (Thanks to Vladimir Karpinsky for the Moscow changes.)
|
|
|
|
Changes affecting data format
|
|
|
|
A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data.
|
|
The new file's extended format allows multiple country codes per zone.
|
|
The older file is still installed but is deprecated; its format is
|
|
not changing and it will still be distributed for a while, but new
|
|
applications should use the new file.
|
|
|
|
The new file format simplifies maintenance of obscure locations.
|
|
To test this, it adds coverage for the Crozet Islands and the
|
|
Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.)
|
|
|
|
The file 'iso3166.tab' is planned to switch from ASCII to UTF-8.
|
|
It is still ASCII now, but commentary about the switch has been added.
|
|
The new file 'zone1970.tab' already uses UTF-8.
|
|
|
|
Changes affecting code
|
|
|
|
'localtime', 'mktime', etc. now use much less stack space if ALL_STATE
|
|
is defined. (Thanks to Elliott Hughes for reporting the problem.)
|
|
|
|
'zic' no longer mishandles input when ignoring case in locales that
|
|
are not compatible with English, e.g., unibyte Turkish locales when
|
|
compiled with HAVE_GETTEXT.
|
|
|
|
Error diagnostics of 'zic' and 'yearistype' have been reworded so that
|
|
they no longer use ASCII '-' as if it were a dash.
|
|
|
|
'zic' now rejects output file names that contain '.' or '..' components.
|
|
(Thanks to Tim Parenti for reporting the problem.)
|
|
|
|
'zic -v' now warns about output file names that do not follow
|
|
POSIX rules, or that contain a digit or '.'. (Thanks to Arthur
|
|
David Olson for starting the ball rolling on this.)
|
|
|
|
Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0.
|
|
|
|
Changes affecting build procedure
|
|
|
|
'zic' no longer links in localtime.o and asctime.o, as they're not needed.
|
|
(Thanks to John Cochran.)
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
The 'Theory' file documents legacy names, the longstanding
|
|
exceptions to the POSIX-inspired file name rules.
|
|
|
|
The 'zic' documentation clarifies the role of time types when
|
|
interpreting dates. (Thanks to Arthur David Olson.)
|
|
|
|
Documentation and commentary now prefer UTF-8 to US-ASCII,
|
|
allowing the use of proper accents in foreign words and names.
|
|
Code and data have not changed because of this. (Thanks to
|
|
Garrett Wollman, Ian Abbott, and Guy Harris for helping to debug
|
|
this.)
|
|
|
|
Non-HTML documentation and commentary now use plain-text URLs instead of
|
|
HTML insertions, and are more consistent about bracketing URLs when they
|
|
are not already surrounded by white space. (Thanks to suggestions by
|
|
Steffen Nurpmeso.)
|
|
|
|
There is new commentary about Xujiahui Observatory, the five time-zone
|
|
project in China from 1918 to 1949, timekeeping in Japanese-occupied
|
|
Shanghai, and Tibet Time in the 1950s. The sharp-eyed can spot the
|
|
warlord Jin Shuren in the data.
|
|
|
|
Commentary about the coverage of each Russian zone has been standardized.
|
|
(Thanks to Tim Parenti).
|
|
|
|
There is new commentary about contemporary timekeeping in Ethiopia.
|
|
|
|
Obsolete comments about a 2007 proposal for DST in Kuwait has been removed.
|
|
|
|
There is new commentary about time in Poland in 1919.
|
|
|
|
Proper credit has been given to DST inventor George Vernon Hudson.
|
|
|
|
Commentary about time in Metlakatla, AK and Resolute, NU has been
|
|
improved, with a new source for the former.
|
|
|
|
In zone.tab, Pacific/Easter no longer mentions Salas y Gómez, as it
|
|
is uninhabited.
|
|
|
|
Commentary about permanent Antarctic bases has been updated.
|
|
|
|
Several typos have been corrected. (Thanks to Tim Parenti for
|
|
contributing some of these fixes.)
|
|
|
|
tz-link.htm now mentions the JavaScript libraries Moment Timezone,
|
|
TimezoneJS.Date, Walltime-js, and Timezone. (Thanks to a heads-up
|
|
from Matt Johnson.) Also, it mentions the Go 'latlong' package.
|
|
(Thanks to a heads-up from Dirkjan Ochtman.)
|
|
|
|
The files usno1988, usno1989, usno1989a, usno1995, usno1997, and usno1998
|
|
have been removed. These obsolescent US Naval Observatory entries were no
|
|
longer helpful for maintenance. (Thanks to Tim Parenti for the suggestion.)

Egypt's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00.
|
|
(Thanks to Imed Chihi.) Guess that from 2015 on Egypt will temporarily
|
|
switch to standard time at 24:00 the last Thursday before Ramadan, and
|
|
back to DST at 00:00 the first Friday after Ramadan.
|
|
|
|
Similarly, Morocco's are June 28 at 03:00 and August 2 at 02:00. (Thanks
|
|
to Milamber Space Network.) Guess that from 2015 on Morocco will
|
|
temporarily switch to standard time at 03:00 the last Saturday before
|
|
Ramadan, and back to DST at 02:00 the first Saturday after Ramadan.
|
|
|
|
Changes affecting past time stamps
|
|
|
|
The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of
|
|
"MSD" for Moscow's double daylight time in summer 1921. Also, a typo
|
|
"VLASST" has been repaired to be "VLAST" for Vladivostok summer time
|
|
in 1991. (Thanks to Hank W. for reporting the problems.)
|
|
|
|
Changes affecting commentary
|
|
|
|
tz-link.htm now cites RFC 7265 for jCal, mentions PTP and the
|
|
draft CalDAV extension, updates URLs for TSP, TZInfo, IATA, and
|
|
removes stale pointers to World Time Explorer and WORLDTIME.

Release 2014d - 2014-05-27 21:34:40 -0700
|
|
|
|
Changes affecting code
|
|
|
|
zic no longer generates files containing time stamps before the Big Bang.
|
|
This works around GNOME bug 730332
|
|
<https://bugzilla.gnome.org/show_bug.cgi?id=730332>.
|
|
(Thanks to Leonardo Chiquitto for reporting the bug, and to
|
|
Arthur David Olson and James Cloos for suggesting improvements to the fix.)
|
|
|

Changes affecting documentation
|
|
|
|
tz-link.htm now mentions GNOME.

Changes affecting near-future time stamps
|
|
|
|
Egypt observes DST starting 2014-05-15 at 24:00.
|
|
(Thanks to Ahmad El-Dardiry and Gunther Vermier.)
|
|
Details have not been announced, except that DST will not be observed
|
|
during Ramadan. Guess that DST will stop during the same Ramadan dates as
|
|
Morocco, and that Egypt's future spring and fall transitions will be the
|
|
same as 2010 when it last observed DST, namely April's last Friday at
|
|
00:00 to September's last Thursday at 23:00 standard time. Also, guess
|
|
that Ramadan transitions will be at 00:00 standard time.
|
|
|
|
Changes affecting code
|
|
|
|
zic now generates transitions for minimum time values, eliminating guesswork
|
|
when handling low-valued time stamps. (Thanks to Arthur David Olson.)
|
|
|
|
Port to Cygwin sans glibc. (Thanks to Arthur David Olson.)
|

Changes affecting near-future time stamps
|
|
|
|
Crimea switches to Moscow time on 2014-03-30 at 02:00 local time.
|
|
(Thanks to Alexander Krivenyshev.) Move its zone.tab entry from UA to RU.
|
|
|
|
New entry for Troll station, Antarctica. (Thanks to Paul-Inge Flakstad and
|
|
Bengt-Inge Larsson.) This is currently an approximation; a better version
|
|
will require the zic and localtime fixes mentioned below, and the plan is
|
|
to wait for a while until at least the zic fixes propagate.
|
|
|
|
Changes affecting code
|
|
|
|
'zic' and 'localtime' no longer reject locations needing four transitions
|
|
per year for the foreseeable future. (Thanks to Andrew Main (Zefram).)
|
|
Also, 'zic' avoids some unlikely failures due to integer overflow.
|
|
|
|
Changes affecting build procedure
|
|
|
|
'make check' now detects Rule lines defined but never used.
|
|
The NZAQ rules, an instance of this problem, have been removed.
|
|
|
|
Changes affecting commentary and documentation
|
|
|
|
Fix Tuesday/Thursday typo in description of time in Israel.
|
|
(Thanks to Bert Katz via Pavel Kharitonov and Mike Frysinger.)
|
|
|
|
Microsoft Windows 8.1 doesn't support tz database names. (Thanks
|
|
to Donald MacQueen.) Instead, the Microsoft Windows Store app
|
|
library supports them.
|
|
|
|
Add comments about Johnston Island time in the 1960s.
|

Turkey begins DST on 2014-03-31, not 03-30. (Thanks to Faruk Pasin for
|
|
the heads-up, and to Tim Parenti for simplifying the update.)
|
|
|
|
Changes affecting past time stamps
|
|
|

Fiji ended DST on 2014-01-19 at 02:00, not the previously-scheduled 03:00.
|

(Thanks to Steffen Thorsen.)
|
|
|
|
Ukraine switched from Moscow to Eastern European time on 1990-07-01
|
|
(not 1992-01-01), and observed DST during the entire next winter.
|
|
(Thanks to Vladimir in Moscow via Alois Treindl.)
|
|
|
|
In 1988 Israel observed DST from 04-10 to 09-04, not 04-09 to 09-03.

Several changes affect tz-link.htm, the main web page.
|
|
|
|
Mention Time.is (thanks to Even Scharning) and WX-now (thanks to

Jordan switches back to standard time at 00:00 on December 20, 2013.
|
|
The 2006-2011 transition schedule is planned to resume in 2014.
|

In 2004, Cuba began DST on March 28, not April 4.
|
|
(Thanks to Steffen Thorsen.)
|
|
|
|
Changes affecting code
|
|
|
|
The compile-time flag NOSOLAR has been removed, as nowadays the
|
|
benefit of slightly shrinking runtime table size is outweighed by the
|
|
cost of disallowing potential future updates that exceed old limits.
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
The files solar87, solar88, and solar89 are no longer distributed.
|
|
They were a negative experiment - that is, a demonstration that
|
|
tz data can represent solar time only with some difficulty and error.
|
|
Their presence in the distribution caused confusion, as Riyadh
|
|
civil time was generally not solar time in those years.
|
|
|
|
tz-link.htm now mentions Noda Time. (Thanks to Matt Johnson.)
|
|
|
|
|
|
Release 2013h - 2013-10-25 15:32:32 -0700
|
|

Changes affecting current and future time stamps:
|
|
|
|
Libya has switched its time zone back to UTC+2 without DST,
|
|
instead of UTC+1 with DST. (Thanks to Even Scharning.)
|
|
|
|
Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.
|
|
(Thanks to Gwillim Law.)
|
|
|
|
Changes affecting future time stamps:
|
|
|
|
Acre and (we guess) western Amazonas will switch from UTC-4 to UTC-5
|
|
on 2013-11-10. This affects America/Rio_Branco and America/Eirunepe.
|
|
(Thanks to Steffen Thorsen.)
|
|
|
|
Add entries for DST transitions in Morocco in the year 2038.
|
|
This avoids some year-2038 glitches introduced in 2013g.
|
|
(Thanks to Yoshito Umaoka for reporting the problem.)
|
|
|
|
Changes affecting API
|
|
|
|
The 'tzselect' command no longer requires the 'select' command,
|
|
and should now work with /bin/sh on more platforms. It also works
|
|
around a bug in BusyBox awk before version 1.21.0. (Thanks to
|
|
Patrick 'P. J.' McDermott and Alan Barrett.)
|
|
|
|
Changes affecting code
|
|
|
|
Fix localtime overflow bugs with 32-bit unsigned time_t.
|
|
|
|
zdump no longer assumes sscanf returns maximal values on overflow.
|
|
|
|
Changes affecting the build procedure
|
|
|
|
The builder can specify which programs to use, if any, instead of
|
|
'ar' and 'ranlib', and libtz.a is now built locally before being
|
|
installed. (Thanks to Michael Forney.)
|
|
|
|
A dependency typo in the 'zdump' rule has been fixed.
|
|
(Thanks to Andrew Paprocki.)
|
|
|
|
The Makefile has been simplified by assuming that 'mkdir -p' and 'cp -f'
|
|
work as specified by POSIX.2-1992 or later; this is portable nowadays.
|
|
|
|
'make clean' no longer removes 'leapseconds', since it's
|
|
host-independent and is part of the distribution.
|
|
|
|
The unused makefile macros TZCSRCS, TZDSRCS, DATESRCS have been removed.
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
tz-link.htm now mentions TC TIMEZONE's draft time zone service protocol
|
|
(thanks to Mike Douglass) and TimezoneJS.Date (thanks to Jim Fehrle).
|
|
|
|
Update URLs in tz-link page. Add URLs for Microsoft Windows, since
|
|
8.1 introduces tz support. Remove URLs for Tru64 and UnixWare (no
|
|
longer maintained) and for old advisories. SOFA now does C.
|
|
|
|
Release 2013g - 2013-09-30 21:08:26 -0700
|
|
|
|
Changes affecting current and near-future time stamps
|
|
|
|
Morocco now observes DST from the last Sunday in March to the last
|
|
Sunday in October, not April to September respectively. (Thanks
|
|
to Steffen Thorsen.)
|
|
|
|
Changes affecting 'zic'
|
|
|
|
'zic' now runs on platforms that lack both hard links and symlinks.
|
|
(Thanks to Theo Veenker for reporting the problem, for MinGW.)
|
|
Also, fix some bugs on platforms that lack hard links but have symlinks.
|
|
|
|
'zic -v' again warns that Asia/Tehran has no POSIX environment variable
|
|
to predict the far future, fixing a bug introduced in 2013e.
|
|
|
|
Changes affecting the build procedure
|
|
|
|
The 'leapseconds' file is again put into the tzdata tarball.
|
|
Also, 'leapseconds.awk', so tzdata is self-contained. (Thanks to
|
|
Matt Burgess and Ian Abbott.) The timestamps of these and other
|
|
dependent files in tarballs are adjusted more consistently.
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
The README file is now part of the data tarball as well as the code.
|
|
It now states that files are public domain unless otherwise specified.
|
|
(Thanks to Andrew Main (Zefram) for asking for clarifications.)
|
|
Its details about the 1989 release moved to a place of honor near
|
|
the end of NEWS.

Changes affecting near-future time stamps
|
|
|
|
Tocantins will very likely not observe DST starting this spring.
|
|
(Thanks to Steffen Thorsen.)
|
|
|
|
Jordan will likely stay at UTC+3 indefinitely, and will not fall
|
|
back this fall.
|
|
|
|
Palestine will fall back at 00:00, not 01:00. (Thanks to Steffen Thorsen.)
|
|
|
|
Changes affecting API
|
|
|
|
The types of the global variables 'timezone' and 'altzone' (if present)
|
|
have been changed back to 'long'. This is required for 'timezone'
|
|
by POSIX, and for 'altzone' by common practice, e.g., Solaris 11.
|
|
These variables were originally 'long' in the tz code, but were
|
|
mistakenly changed to 'time_t' in 1987; nobody reported the
|
|
incompatibility until now. The difference matters on x32, where
|
|
'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.)
|
|
|
|
Changes affecting the build procedure
|
|
|
|
Avoid long strings in leapseconds.awk to work around a mawk bug.
|
|
(Thanks to Cyril Baurand.)
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
New file 'NEWS' that contains release notes like this one.
|
|
|
|
Paraguay's law does not specify DST transition time; 00:00 is customary.
|
|
(Thanks to Waldemar Villamayor-Venialbo.)
|
|
|
|
Minor capitalization fixes.
|
|
|
|
Changes affecting version-control only
|
|
|
|
The experimental GitHub repository now contains annotated and
|
|
signed tags for recent releases, e.g., '2013e' for Release 2013e.
|
|
Releases are tagged starting with 2012e; earlier releases were
|
|
done differently, and tags would either not have a simple name or
|
|
not exactly match what was released.
|
|
|
|
'make set-timestamps' is now simpler and a bit more portable.
|
|
|
|
|
|
Release 2013e - 2013-09-19 23:50:04 -0700
|
|
|
|
Changes affecting near-future time stamps
|
|
|
|
This year Fiji will start DST on October 27, not October 20.
|
|
(Thanks to David Wheeler for the heads-up.) For now, guess that
|
|
Fiji will continue to spring forward the Sunday before the fourth
|
|
Monday in October.
|
|
|
|
Changes affecting current and future time zone abbreviations
|
|
|
|
Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian
|
|
time zone abbreviations since 1932. (Thanks to George Ziegler,
|
|
Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and
|
|
Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura,
|
|
Asia/Makassar, and Asia/Pontianak.
|
|
|
|
Use ART (UTC-3, standard time), rather than WARST (also UTC-3, but
|
|
daylight saving time) for San Luis, Argentina since 2009.
|
|
|
|
Changes affecting Godthåb time stamps after 2037 if version mismatch
|
|
|
|
Allow POSIX-like TZ strings where the transition time's hour can
|
|
range from -167 through 167, instead of the POSIX-required 0
|
|
through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the
|
|
new Fiji rules. This is a more-compact way to represent
|
|
far-future time stamps for America/Godthab, America/Santiago,
|
|
Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem,
|
|
Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by
|
|
this change. (Derived from a suggestion by Arthur David Olson.)
|
|
|
|
Allow POSIX-like TZ strings where daylight saving time is in
|
|
effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western
|
|
Argentina Summer Time all year. This supports a more-compact way
|
|
to represent the 2013d data for America/Argentina/San_Luis.
|
|
Because of the change for San Luis noted above this change does not
|
|
affect the current data. (Thanks to Andrew Main (Zefram) for
|
|
suggestions that improved this change.)
|
|
|
|
Where these two TZ changes take effect, there is a minor extension
|
|
to the tz file format in that it allows new values for the
|
|
embedded TZ-format string, and the tz file format version number
|
|
has therefore been increased from 2 to 3 as a precaution.
|
|
Version-2-based client code should continue to work as before for
|
|
all time stamps before 2038. Existing version-2-based client code
|
|
(tzcode, GNU/Linux, Solaris) has been tested on version-3-format
|
|
files, and typically works in practice even for time stamps after
|
|
2037; the only known exception is America/Godthab.
|
|
|
|
Changes affecting time stamps before 1970
|
|
|
|
Pacific/Johnston is now a link to Pacific/Honolulu. This corrects
|
|
some errors before 1947.
|
|
|
|
Some zones have been turned into links, when they differ from existing
|
|
zones only in older data entries that were likely invented or that
|
|
differ only in LMT or transitions from LMT. These changes affect
|
|
only time stamps before 1943. The affected zones are:
|
|
Africa/Juba, America/Anguilla, America/Aruba, America/Dominica,
|
|
America/Grenada, America/Guadeloupe, America/Marigot,
|
|
America/Montserrat, America/St_Barthelemy, America/St_Kitts,
|
|
America/St_Lucia, America/St_Thomas, America/St_Vincent,
|
|
America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for
|
|
confirming that the old Europe/Vaduz zone was wrong and the new
|
|
link is better for WWII-era times.)
|
|
|
|
Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects
|
|
America/Cayman, America/Jamaica and America/Grand_Turk time stamps
|
|
from 1890 to 1912.
|
|
|
|
Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46.
|
|
This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks
|
|
to Alois Treindl).
|
|
|
|
Change the date of the circa-1850 Zurich transition from 1849-09-12
|
|
to 1853-07-16, overriding Shanks with data from Messerli about
|
|
postal and telegraph time in Switzerland.
|
|
|
|
Changes affecting time zone abbreviations before 1970
|
|
|
|
For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932,
|
|
as Jakarta was called Batavia back then.
|
|
|
|
Changes affecting API
|
|
|
|
The 'zic' command now outputs a dummy transition when far-future
|
|
data can't be summarized using a TZ string, and uses a 402-year
|
|
window rather than a 400-year window. For the current data, this
|
|
affects only the Asia/Tehran file. It does not affect any of the
|
|
time stamps that this file represents, so zdump outputs the same
|
|
information as before. (Thanks to Andrew Main (Zefram).)
|
|
|
|
The 'date' command has a new '-r' option, which lets you specify
|
|
the integer time to display, a la FreeBSD.
|
|
|
|
The 'tzselect' command has two new options '-c' and '-n', which lets you
|
|
select a zone based on latitude and longitude.
|
|
|
|
The 'zic' command's '-v' option now warns about constructs that
|
|
require the new version-3 binary file format. (Thanks to Arthur
|
|
David Olson for the suggestion.)
|
|
|
|
Support for floating-point time_t has been removed.
|
|
It was always dicey, and POSIX no longer requires it.
|
|
(Thanks to Eric Blake for suggesting to the POSIX committee to
|
|
remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy
|
|
Heninger, Arthur David Olson, and Alois Treindl, for reporting
|
|
bugs and elucidating some of the corners of the old floating-point
|
|
implementation.)
|
|
|
|
The signatures of 'offtime', 'timeoff', and 'gtime' have been
|
|
changed back to the old practice of using 'long' to represent UT
|
|
offsets. This had been inadvertently and mistakenly changed to
|
|
'int_fast32_t'. (Thanks to Christos Zoulas.)
|
|
|
|
The code avoids undefined behavior on integer overflow in some
|
|
more places, including gmtime, localtime, mktime and zdump.
|
|
|
|
Changes affecting the zdump utility
|
|
|
|
zdump now outputs "UT" when referring to Universal Time, not "UTC".
|
|
"UTC" does not make sense for time stamps that predate the introduction
|
|
of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen
|
|
for clarifying UT vs UTC.)
|
|
|
|
Data changes affecting behavior of tzselect and similar programs
|
|
|
|
Country code BQ is now called the more-common name "Caribbean Netherlands"
|
|
rather than the more-official "Bonaire, St Eustatius & Saba".
|
|
|
|
Remove from zone.tab the names America/Montreal, America/Shiprock,
|
|
and Antarctica/South_Pole, as they are equivalent to existing
|
|
same-country-code zones for post-1970 time stamps. The data entries for
|
|
these names are unchanged, so the names continue to work as before.
|
|
|
|
Changes affecting code internals
|
|
|
|
zic -c now runs way faster on 64-bit hosts when given large numbers.
|
|
|
|
zic now uses vfprintf to avoid allocating and freeing some memory.
|
|
|
|
tzselect now computes the list of continents from the data,
|
|
rather than have it hard-coded.
|
|
|
|
Minor changes pacify GCC 4.7.3 and GCC 4.8.1.
|
|
|
|
Changes affecting the build procedure
|
|
|
|
The 'leapseconds' file is now generated automatically from a
|
|
new file 'leap-seconds.list', which is a copy of
|
|
<ftp://time.nist.gov/pub/leap-seconds.list>.
|
|
A new source file 'leapseconds.awk' implements this.
|
|
The goal is simplification of the future maintenance of 'leapseconds'.
|
|
|
|
When building the 'posix' or 'right' subdirectories, if the
|
|
subdirectory would be a copy of the default subdirectory, it is
|
|
now made a symbolic link if that is supported. This saves about
|
|
2 MB of file system space.
|
|
|
|
The links America/Shiprock and Antarctica/South_Pole have been
|
|
moved to the 'backward' file. This affects only nondefault builds
|
|
that omit 'backward'.
|
|
|
|
Changes affecting version-control only
|
|
|
|
.gitignore now ignores 'date'.
|
|
|
|
Changes affecting documentation and commentary
|
|
|
|
Changes to the 'tzfile' man page
|
|
|
|
It now mentions that the binary file format may be extended in
|
|
future versions by appending data.
|
|
|
|
It now refers to the 'zdump' and 'zic' man pages.
|
|
|
|
Changes to the 'zic' man page
|
|
|
|
It lists conditions that elicit a warning with '-v'.
|
|
|
|
It says that the behavior is unspecified when duplicate names
|
|
are given, or if the source of one link is the target of another.
|
|
|
|
Its examples are updated to match the latest data.
|
|
|
|
The definition of white space has been clarified slightly.
|
|
(Thanks to Michael Deckers.)
|
|
|
|
Changes to the 'Theory' file
|
|
|
|
There is a new section about the accuracy of the tz database,
|
|
describing the many ways that errors can creep in, and
|
|
explaining why so many of the pre-1970 time stamps are wrong or
|
|
misleading (thanks to Steve Allen, Lester Caine, and Garrett
|
|
Wollman for discussions that contributed to this).
|
|
|
|
The 'Theory' file describes LMT better (this follows a
|
|
suggestion by Guy Harris).
|
|
|
|
It refers to the 2013 edition of POSIX rather than the 2004 edition.
|
|
|
|
It's mentioned that excluding 'backward' should not affect the
|
|
other data, and it suggests at least one zone.tab name per
|
|
inhabited country (thanks to Stephen Colebourne).
|
|
|
|
Some longstanding restrictions on names are documented, e.g.,
|
|
'America/New_York' precludes 'America/New_York/Bronx'.
|
|
|
|
It gives more reasons for the 1970 cutoff.
|
|
|
|
It now mentions which time_t variants are supported, such as
|
|
signed integer time_t. (Thanks to Paul Goyette for reporting
|
|
typos in an experimental version of this change.)
|
|
|
|
(Thanks to Philip Newton for correcting typos in these changes.)
|
|
|
|
Documentation and commentary is more careful to distinguish UT in
|
|
general from UTC in particular. (Thanks to Steve Allen.)
|
|
|
|
Add a better source for the Zurich 1894 transition.
|
|
(Thanks to Pierre-Yves Berger.)
|
|
|
|
Update shapefile citations in tz-link.htm. (Thanks to Guy Harris.)
|
|
|
|
|
|
Release 2013d - 2013-07-05 07:38:01 -0700
|
|
|
|
Changes affecting future time stamps:
|
|
|
|
Morocco's midsummer transitions this year are July 7 and August 10,
|
|
not July 9 and August 8. (Thanks to Andrew Paprocki.)
|
|
|
|
Israel now falls back on the last Sunday of October.
|
|
(Thanks to Ephraim Silverberg.)
|
|
|
|
Changes affecting past time stamps:
|
|
|
|
Specify Jerusalem's location more precisely; this changes the pre-1880
|
|
times by 2 s.
|
|
|
|
Changing affecting metadata only:
|
|
|
|
Fix typos in the entries for country codes BQ and SX.
|
|
|
|
Changes affecting code:
|
|
|
|
Rework the code to fix a bug with handling Australia/Macquarie on
|
|
32-bit hosts (thanks to Arthur David Olson).
|
|
|
|
Port to platforms like NetBSD, where time_t can be wider than long.
|
|
|
|
Add support for testing time_t types other than the system's.
|
|
Run 'make check_time_t_alternatives' to try this out.
|
|
Currently, the tests fail for unsigned time_t;
|
|
this should get fixed at some point.
|
|
|
|
Changes affecting documentation and commentary:
|
|
|
|
Deemphasize the significance of national borders.
|
|
|
|
Update the zdump man page.
|
|
|
|
Remove obsolete NOID comment (thanks to Denis Excoffier).
|
|
|
|
Update several URLs and comments in the web pages.
|
|
|
|
Spelling fixes (thanks to Kevin Lyda and Jonathan Leffler).
|
|
|
|
Update URL for CLDR Zone->Tzid table (thanks to Yoshito Umaoka).
|
|
|
|
|
|
Release 2013c - 2013-04-19 16:17:40 -0700
|
|
|
|
Changes affecting current and future time stamps:
|
|
|
|
Palestine observed DST starting March 29, 2013. (Thanks to
|
|
Steffen Thorsen.) From 2013 on, Gaza and Hebron both observe DST,
|
|
with the predicted rules being the last Thursday in March at 24:00
|
|
to the first Friday on or after September 21 at 01:00.
|
|
|
|
Assume that the recent change to Paraguay's DST rules is permanent,
|
|
by moving the end of DST to the 4th Sunday in March every year.
|
|
(Thanks to Carlos Raúl Perasso.)
|
|
|
|
Changes affecting past time stamps:
|
|
|
|
Fix some historical data for Palestine to agree with that of
|
|
timeanddate.com, as follows:
|
|
|
|
The spring 2008 change in Gaza and Hebron was on 00:00 Mar 28, not
|
|
00:00 Apr 1.
|
|
|
|
The fall 2009 change in Gaza and Hebron on Sep 4 was at 01:00, not
|
|
02:00.
|
|
|
|
The spring 2010 change in Hebron was 00:00 Mar 26, not 00:01 Mar 27.
|
|
|
|
The spring 2011 change in Gaza was 00:01 Apr 1, not 12:01 Apr 2.
|
|
|
|
The spring 2011 change in Hebron on Apr 1 was at 00:01, not 12:01.
|
|
|
|
The fall 2011 change in Hebron on Sep 30 was at 00:00, not 03:00.
|
|
|
|
Fix times of habitation for Macquarie to agree with the Tasmania
|
|
Parks & Wildlife Service history, which indicates that permanent
|
|
habitation was 1899-1919 and 1948 on.
|
|
|
|
Changing affecting metadata only:
|
|
|
|
Macquarie Island is politically part of Australia, not Antarctica.
|
|
(Thanks to Tobias Conradi.)
|
|
|
|
Sort Macquarie more-consistently with other parts of Australia.
|
|
(Thanks to Tim Parenti.)
|
|
|
|
|
|
Release 2013b - 2013-03-10 22:33:40 -0700
|
|
|
|
Changes affecting current and future time stamps:
|
|
|
|
Haiti uses US daylight-saving rules this year, and presumably future years.
|
|
This changes time stamps starting today. (Thanks to Steffen Thorsen.)
|
|
|
|
Paraguay will end DST on March 24 this year.
|
|
(Thanks to Steffen Thorsen.) For now, assume it's just this year.
|
|
|
|
Morocco does not observe DST during Ramadan;
|
|
try to predict Ramadan in Morocco as best we can.
|
|
(Thanks to Erik Homoet for the heads-up.)
|
|
|
|
Changes affecting commentary:
|
|
|
|
Update URLs in tz-link page. Add URLs for webOS, BB10, iOS.
|
|
Update URL for Solaris. Mention Internet RFC 6557.
|
|
Update Internet RFCs 2445->5545, 2822->5322.
|
|
Switch from FTP to HTTP for Internet RFCs.
|
|
|
|
|
|
Release 2013a - 2013-02-27 09:20:35 -0800
|
|
|
|
Change affecting binary data format:
|
|
|
|
The zone offset at the end of version-2-format zone files is now
|
|
allowed to be 24:00, as per POSIX.1-2008. (Thanks to Arthur David Olson.)
|
|
|
|
Changes affecting current and future time stamps:
|
|
|
|
Chile's 2013 rules, and we guess rules for 2014 and later, will be
|
|
the same as 2012, namely Apr Sun>=23 03:00 UTC to Sep Sun>=2 04:00 UTC.
|
|
(Thanks to Steffen Thorsen and Robert Elz.)
|
|
|
|
New Zones Asia/Khandyga, Asia/Ust-Nera, Europe/Busingen.
|
|
(Thanks to Tobias Conradi and Arthur David Olson.)
|
|
|
|
Many changes affect historical time stamps before 1940.
|
|
These were deduced from: Milne J. Civil time. Geogr J. 1899
|
|
Feb;13(2):173-94 <http://www.jstor.org/stable/1774359>.
|
|
|
|
Changes affecting the code:
|
|
|
|
Fix zic bug that mishandled Egypt's 2010 changes (this also affected
|
|
the data). (Thanks to Arthur David Olson.)
|
|
|
|
Fix localtime bug when time_t is unsigned and data files were generated
|
|
by a signed time_t system. (Thanks to Doug Bailey for reporting and
|
|
to Arthur David Olson for fixing.)
|
|
|
|
Allow the email address for bug reports to be set by the packager.
|
|
The default is tz@iana.org, as before. (Thanks to Joseph S. Myers.)
|
|
|
|
Update HTML checking to be compatible with Ubuntu 12.10.
|
|
|
|
Check that files are a safe subset of ASCII. At some point we may
|
|
relax this requirement to a safe subset of UTF-8. Without the
|
|
check, some non-UTF-8 encodings were leaking into the distribution.
|
|
|
|
Commentary changes:
|
|
|
|
Restore a comment about copyright notices that was inadvertently deleted.
|
|
(Thanks to Arthur David Olson.)
|
|
|
|
Improve the commentary about which districts observe what times
|
|
in Russia. (Thanks to Oscar van Vlijmen and Arthur David Olson).
|
|
|
|
Add web page links to tz.js.
|
|
|
|
Add "Run by the Monkeys" to tz-art. (Thanks to Arthur David Olson.)
|
|
|
|
|
|
Release 2012j - 2012-11-12 18:34:49 -0800
|
|
|
|
Libya moved to CET this weekend, but with DST planned next year.
|
|
(Thanks to Even Scharning, Steffen Thorsen, and Tim Parenti.)
|
|
|
|
Signatures now have the extension .asc, not .sign, as that's more
|
|
standard. (Thanks to Phil Pennock.)
|
|
|
|
The output of 'zdump --version', and of 'zic --version', now
|
|
uses a format that is more typical for --version.
|
|
(Thanks to Joseph S. Myers.)
|
|
|
|
The output of 'tzselect --help', 'zdump --help', and 'zic --help'
|
|
now uses tz@iana.org rather than the old elsie address.
|
|
|
|
zic -v now complains about abbreviations that are less than 3
|
|
or more than 6 characters, as per Posix. Formerly, it checked
|
|
for abbreviations that were more than 3.
|
|
|
|
'make public' no longer puts its temporary directory under /tmp,
|
|
and uses the just-built zic rather than the system zic.
|
|
|
|
Various fixes to documentation and commentary.
|
|
|
|
|
|
Release 2012i - 2012-11-03 12:57:09 -0700
|
|
|
|
Cuba switches from DST tomorrow at 01:00. (Thanks to Steffen Thorsen.)
|
|
|
|
Linker flags can now be specified via LDFLAGS.
|
|
AWK now defaults to 'awk', not 'nawk'.
|
|
The shell in tzselect now defaults to /bin/bash, but this can
|
|
be overridden by specifying KSHELL.
|
|
The main web page now mentions the unofficial GitHub repository.
|
|
(Thanks to Mike Frysinger.)
|
|
|
|
Tarball signatures can now be built by running 'make signatures'.
|
|
There are also new makefile rules 'tarballs', 'check_public', and
|
|
separate makefile rules for each tarball and signature file.
|
|
A few makefile rules are now more portable to strict POSIX.
|
|
|
|
The main web page now lists the canonical IANA URL.
|
|
|
|
|

|
|

|
the instances of 'register' were kept.

|
|
|
|
Palestine fall 2012. (Thanks to Steffen Thorsen.)
|
|
|
|
Assume C89.
|
|
|
|
To attack the version-number problem, this release ships the file
|
|
'Makefile' (which contains the release number) in both the tzcode and
|
|
the tzdata tarballs. The two Makefiles are identical, and should be
|
|
identical in any matching pair of tarballs, so it shouldn't matter
|
|
which order you extract the tarballs. Perhaps we can come up with a
|
|
better version-number scheme at some point; this scheme does have the
|
|
virtue of not adding more files.
|
|

Release 2012b - 2012-03-02 12:29:15 +0700
|
|
|
|
There is just one change to tzcode2012b (compared with 2012a):
|
|
the Makefile that was accidentally included with 2012a has been
|
|
replaced with the version that should have been there, which is
|
|
identical with the previous version (from tzcode2011i).
|
|
|
|
There are just two changes in tzdata2012b compared with 2012a.
|
|
|
|
Most significantly, summer time in Cuba has been delayed 3 weeks
|
|
(now starts April 1 rather than March 11). Since Mar 11 (the old start
|
|
date, as listed in 2012a) is just a little over a week away, this
|
|
change is urgent.
|
|
|
|
Less importantly, an excess tab in one of the changes in zone.tab
|
|
in 2012a has been removed.
|
|
|
|
|
|
Release 2012a - 2012-03-01 18:28:10 +0700
|
|
|
|
The changes in tzcode2012a (compared to the previous version, 2011i)
|
|
are entirely to the README and tz-art.htm and tz-link.htm files, if
|
|
none of those concern you, you can ignore the code update. The changes
|
|
reflect the changed addresses for the mailing list and the code and
|
|
data distribution points & methods (and a link to DateTime::TimeZone::Tzfile
|
|
has been added to tz-link.htm).
|
|
|
|
In tzdata2012a (compared to the previous release, which was 2011n)
|
|
the major changes are:
|
|
Chile 2011/2012 and 2012/2013 summer time date adjustments.
|
|
Falkland Islands onto permanent summer time (we're assuming for the
|
|
foreseeable future, though 2012 is all we're fairly certain of.)
|
|
Armenia has abolished Summer Time.
|
|
Tokelau jumped the International Date Line back last December
|
|
(just the same as their near neighbour, Samoa).
|
|
America/Creston is a new zone for a small area of British Columbia
|
|
There will be a leapsecond 2012-06-30 23:59:60 UTC.
|
|
|
|
Other minor changes are:
|
|
Corrections to 1918 Canadian summer time end dates.
|
|
Updated URL for UK time zone history (in comments)
|
|
A few typos in Le Corre's list of free French place names (comments)
|
|
|
|
|
|
Release data2011n - 2011-10-30 14:57:54 +0700
|
|
|
|
There are three changes of note - most urgently, Cuba (America/Havana)
|
|
has extended summer time by two weeks, now to end on Nov 13, rather than
|
|
the (already past) Oct 30. Second, the Pridnestrovian Moldavian Republic
|
|
(Europe/Tiraspol) decided not to split from the rest of Moldova after
|
|
all, and consequently that zone has been removed (again) and reinstated
|
|
in the "backward" file as a link to Europe/Chisinau. And third, the
|
|
end date for Fiji's summer time this summer was moved forward from the
|
|
earlier planned Feb 26, to Jan 22.
|
|
|
|
Apart from that, Moldova (MD) returns to a single entry in zone.tab
|
|
(and the incorrect syntax that was in the 2011m version of that file
|
|
is so fixed - it would have been fixed in a different way had this
|
|
change not happened - that's the "missing" sccs version id).
|
|
|
|
|
|
Release data2011m - 2011-10-24 21:42:16 +0700
|
|
|
|
In particular, the typos in comments in the data (2011-11-17 should have
|
|
been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that
|
|
Tim Parenti noted) have been fixed, and the change for Ukraine has been
|
|
made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to
|
|
Tim Parenti, and also Denys Gavrysh)
|
|
|
|
In addition, I added Europe/Tiraspol to zone.tab.
|
|
|
|
This time, all the files have new version numbers... (including the files
|
|
otherwise unchanged in 2011m that were changed in 2011l but didn't get new
|
|
version numbers there...)
|
|
|
|
|
|
Release data2011l - 2011-10-10 11:15:43 +0700
|
|
|
|
There are just 2 changes that cause different generated tzdata files from
|
|
zic, to Asia/Hebron and Pacific/Fiji - the possible change for Bahia, Brazil
|
|
is included, but commented out. Compared with the diff I sent out last week,
|
|
this version also includes attributions for the sources for the changes
|
|
(in much the same format as ado used, but the html tags have not been
|
|
checked, verified, or used in any way at all, so if there are errors there,
|
|
please let me know.)

The changes were circulated on the time zone mailing list; the only

change since then was the removal of a couple of minimum-length of

abbreviation checks.

changes by Paul Eggert

|
|
|
|
Release code96f-data96g - 1996-05-03 03:09:59 -0000
|
|
[tzcode96f.tar.gz + tzdata96g.tar.gz are both missing!]
|
|
|
|
The changes get us some of the way to fixing the problems noted in Paul
|
|
Eggert's letter yesterday (in addition to a few others). The approach
|
|
has been to make zic a bit smarter about figuring out what time zone
|
|
abbreviations apply just after the time specified in the "UNTIL" part
|
|
of a zone line. Putting the smarts in zic means avoiding having
|
|
transition times show up in both "Zone" lines and "Rule" lines, which
|
|
in turn avoids multiple transition time entries in time zone files.
|
|
(This also makes the zic input files such as "europe" a bit shorter and
|
|
should ease maintenance.)
|
|
|
|
|
|
Release data96f - 1996-04-19 19:20:03 -0000

|
[tzdata96f.tar.gz is missing!]

The only changes are to the "northamerica" file; the time zone
|
|
abbreviation for Denver is corrected to MST (and MDT), and the
|
|
comments for Mexico have been updated.
|
|
|
|
|
|
Release data96e - 1996-03-19 17:37:26 -0500

|
|
Release data95i - 1995-09-26 10:43:26 -0400
|
|
|
|
For Canada/Central, guess that the Sun customer's "one week too
|
|
early" was just a approximation, and the true error is one month
|
|
too early. This is consistent with the rest of Canada.
|
|
|
|
|
|
Release data95h - 1995-09-21 11:26:48 -0400

|
|
Thanks to Bradley White for forwarding news on the leap second.
|
|
|
|
|
|
Release data95d - 1995-07-03 13:26:22 -0400

|
|
|
|
|
|
Release data95c - 1995-07-02 19:19:28 -0400
|
|
|
|
changes to "asia", "backward", "europe", and "southamerica"
|
|
(read: northamericacentrics need not apply)
|
|
|
|
|
|
Release code95c - 1995-03-13 14:00:46 -0500
|
|
|
|
one-line fix for sign extension problems in detzcode
|
|
|
|
|
|
Release 95b - 1995-03-04 11:22:38 -0500
|
|
|
|
Minor changes in both:
|
|
|
|
The "code" file contains a workaround for the lack of "unistd.h" in
|
|
Microsoft C++ version 7.
|
|
|
|
The "data" file contains a fixed "Link" for America/Shiprock.
|
|
|
|
|
|
Release 94h - 1994-12-10 12:51:14 -0500
|
|
|
|
The files:
|
|
|
|
* incorporate the changes to "zdump" and "date" to make changes to
|
|
the "TZ" environment variable permanent;
|
|
|
|
* incorporate the table changes by Paul Eggert;
|
|
|
|
* include (and document) support for universal time specifications in
|
|
data files - but do not (yet) include use of this feature in the
|
|
data files.
|
|
|
|
Think of this as "TZ Classic" - the software has been set up not to break if
|
|
universal time shows up in its input, and data entries have been
|
|
left as is so as not to break existing implementations.
|
|
|
|
|
|
Release data94f - 1994-08-20 12:56:09 -0400

|
|
[tzcode94f.tar.gz is missing!]
|
|
|
|
changes to avoid overflow in difftime, as well as changes to cope
|
|
with the 52/53 challenge in strftime
|
|
|
|
|
|
Release code94e - 1994-03-30 23:32:59 -0500
|
|
|
|
change for the benefit of PCTS
|
|
|
|
|
|
Release 94d - 1994-02-24 15:42:25 -0500
|
|
|

Avoid clashes with POSIX semantics for zones such as GMT+4.
|
|

|
|
|
|
|
|
Release code94c - 1994-02-10 08:52:40 -0500
|
|
|
|
Fix bug where mkdirs was broken unless you compile with
|
|
-fwritable-strings (which is generally losing to do).
|
|
|
|
|
|
Release 94b - 1994-02-07 10:04:33 -0500
|
|
|
|
work by Paul Eggert who notes:
|
|
|
|
I found another book of time zone histories by E W Whitman; it's not
|
|
as extensive as Shanks but has a few goodies of its own. I used it
|
|
to update the tables. I also fixed some more as a result of
|
|
correspondence with Adam David and Peter Ilieve, and move some stray
|
|
links from 'europe' to 'backward'. I corrected some scanning errors
|
|
in usno1989.
|
|
|
|
As far as the code goes, I fixed zic to allow years in the range
|
|
INT_MIN to INT_MAX; this fixed a few boundary conditions around 1900.
|
|
And I cleaned up the zic documentation a little bit.
|
|
|
|
|
|
Release data94a - 1994-02-03 08:58:54 -0500
|
|
|
|
It simply incorporates the recently announced leap second into the
|
|
"leapseconds" file.
|
|
|
|
|
|
Release 93g - 1993-11-22 17:28:27 -0500
|
|
|
|
Paul Eggert has provided a good deal of historic information (based
|
|
on Shanks), and there are some code changes to deal with the buglets
|
|
that crawled out in dealing with the new information.
|
|
|
|
|
|
Release 93f - 1993-10-15 12:27:46 -0400
|
|
|
|
Paul Eggert's changes
|
|
|
|
|
|
Release 93e - 1993-09-05 21:21:44 -0400
|
|
|
|
This has updated data for Israel, England, and Kwajalein. There's
|
|
also an update to "zdump" to cope with Kwajalein's 24-hour jump.
|
|
Thanks to Paul Eggert and Peter Ilieve for the changes.
|
|
|
|
|
|
Release 93d - 1993-06-17 23:34:17 -0400
|
|
|
|
new fix and new data on Israel
|
|
|
|
|
|
Release 93c - 1993-06-06 19:31:55 -0400
|
|
|
|
[not summarized]
|
|
|
|
|
|
Release 93b - 1993-02-02 14:53:58 -0500
|
|
|
|
updated "leapseconds" file
|
|
|
|
|
|
Release 93 - 1993-01-08 07:01:06 -0500
|
|
|
|
At kre's suggestion, the package has been split in two - a code piece
|
|
(which also includes documentation) that's only of use to folks who
|
|
want to recompile things and a data piece useful to anyone who can
|
|
run "zic".
|
|
|
|
The new version has a few changes to the data files, a few
|
|
portability changes, and an off-by-one fix (with thanks to
|
|
Tom Karzes at deshaw.com for providing a description and a
|
|
solution).
|
|
|
|
|
|
Release 92c - 1992-11-21 17:35:36 -0000
|
|
[tz92c.tar.Z is missing!]
|
|
|
|
The fallout from the latest round of DST transitions.
|
|
|
|
There are changes for Portugal, Saskatchewan, and "Pacific-New";
|
|
there's also a change to "zic.c" that makes it portable to more systems.
|
|
|
|
|
|
Release 92 - 1992-04-25 18:17:03 -0000
|
|
[tz92.tar.Z is missing!]
|
|
|
|
By popular demand (well, at any rate, following a request by kre at munnari)
|
|
|
|
|
|
The 1989 update of the time zone package featured:
|
|
|
|
* POSIXization (including interpretation of POSIX-style TZ environment
|
|
variables, provided by Guy Harris),
|
|
* ANSIfication (including versions of "mktime" and "difftime"),
|
|
* SVIDulation (an "altzone" variable)
|
|
* MACHination (the "gtime" function)
|
|
* corrections to some time zone data (including corrections to the rules
|
|
for Great Britain and New Zealand)
|
|
* reference data from the United States Naval Observatory for folks who
|
|
want to do additional time zones
|
|
* and the 1989 data for Saudi Arabia.
|
|
|
|
(Since this code will be treated as "part of the implementation" in some
|
|
places and as "part of the application" in others, there's no good way to
|
|
name functions, such as timegm, that are not part of the proposed ANSI C
|
|
standard; such functions have kept their old, underscore-free names in this
|
|
update.)
|
|
|
|
And the "dysize" function has disappeared; it was present to allow
|
|
compilation of the "date" command on old BSD systems, and a version of "date"
|
|
is now provided in the package. The "date" command is not created when you
|
|
"make all" since it may lack options provided by the version distributed with
|
|
your operating system, or may not interact with the system in the same way
|
|
the native version does.
|
|
|
|
Since POSIX frowns on correct leap second handling, the default behavior of
|
|
the "zic" command (in the absence of a "-L" option) has been changed to omit
|
|
leap second information from its output files.
|
|

Notes
|
|
|
|
This file contains copies of the part of each release announcement
|
|
that talks about the changes in that release. The text has been
|
|
adapted and reformatted for the purposes of this file.
|
|
|
|
Typically a release R consists of a pair of tarball files,
|
|
tzcodeR.tar.gz and tzdataR.tar.gz. However, some releases (e.g.,
|
|
code2010a, data2012c) consist of just one or the other tarball, and a
|
|
few (e.g., code2012c-data2012d) have tarballs with mixed version
|
|
numbers.
|
|
|
|
Release time stamps are taken from the release's commit (for newer,
|
|
git releases), from the newest file in the tarball (for older
|
|
releases, where this info is available) or from the email announcing
|
|
the release (if all else fails; these are marked with a time zone of
|
|
-0000 and an "is missing!" comment).
|
|
|
|
Earlier versions of the code and data were not announced on the tz
|
|
list and are not summarized here.
