Egypt observes DST starting May 15. (Thanks to Ahmad El-Dardiry.)
|
|
|
|
|
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.

zic now generates transitions for minimum time values, eliminating guesswork

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.
|
|

'zic' and 'localtime' no longer reject locations needing four transitions
|
|

|
per year for the forseeable future. (Thanks to Andrew Main (Zefram).)
|
|
|
|
|
Also, 'zic' avoids some unlikely failures due to integer overflow.

Microsoft Windows 8.1 doesn't support tz database names. (Thanks

Turkey begins DST on 2014-03-31, not 03-30. (Thanks to Faruk Pasin for

Ukraine switched from Moscow to Eastern European time on 1990-07-01
|
|
|
|
|
(not 1992-01-01), and observed DST during the entire next winter.
|
|

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.)

|
|
instead of UTC+1 with DST. (Thanks to Even Scharning.)
|
|
|
|
|
|
|
|

Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.
|

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.

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

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
|
|
|

(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.

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.

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.

|
|
|

|
|
It now states that files are public domain unless otherwise specified.
|
|
|
|
|
(Thanks to Andrew Main (Zefram) for asking for clarifications.)

|
|
|

Jordan will likely stay at UTC+3 indefinitely, and will not fall
|
|
|
|
|
back this fall.

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.)

|
|
|
|

|
|
|
|
|
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.

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 Godthab 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 that was likely invented or that
|
|
|
|
|
differs only in LMT or transition 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 Zoulos.)
|
|
|
|
|
|
|
|
|
|
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 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
|
|
|
|
|

|
|
|
|
|
|
|
|

|
|
|

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.
|
|
|

Palestine observed DST starting March 29, 2013. (Thanks to

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 Arthor 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
|
|
|
|
|

|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
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.

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 timezone history (in 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...)

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,

overflow/underflow checks by Arthur David Olson, minus changes to

the "Theory" file about the pending addition of 64-bit data (I grow
|
|
|
|
|
less confident of the changes being accepted with each passing day,

announced leap second at the end of 2005.
|

These reflect changes to limit the length of time zone abbreviations
|
|
|
|
|
and the characters used in those abbreviations.
|
|
|
|
|
|
|
|
|
|
There are also changes to handle POSIX-style "quoted" time zone
|
|
|
|
|
environment variables.
|
|
|
|
|
|
|
|
|
|
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.

Arthur David Olson finessed the "getopt" issue by checking against

both -1 and EOF (regardless of POSIX, SunOS 4.1.1's manual says -1
|
|
|
|
|
is returned while SunOS 5.5's manual says EOF is returned).

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.)

For Canada/Central, guess that the Sun customer's ``one week too

too early. This is consistent with the rest of Canada.

|
|
|
|

Think of this as "TZ Classic"--the software has been set up not to break if

universal time shows up in its input, and the data has been left as is so as
|
|
|
|

not to break existing implementations.

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.

|
|

|
|
"leapseconds" file.

|
|
|
|
|
|
|
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.

There's 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.

|
|
|
|
|
|
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).

|
|
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 timezone 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.
