# On older platforms you may need to scrounge for a POSIX-conforming 'make'.
# For example, on Solaris 10 (2005), use /usr/sfw/bin/gmake or
# /usr/xpg4/bin/make, not /usr/ccs/bin/make.
# To affect how this Makefile works, you can run a shell script like this:

News for the tz database
Release 2023d - 2023-12-21 20:02:24 -0800
Briefly:
Ittoqqortoormiit, Greenland changes time zones on 2024-03-31.
Vostok, Antarctica changed time zones on 2023-12-18.
Casey, Antarctica changed time zones five times since 2020.
Code and data fixes for Palestine timestamps starting in 2072.
A new data file zonenow.tab for timestamps starting now.
Changes to future timestamps
Ittoqqortoormiit, Greenland (America/Scoresbysund) joins most of
the rest of Greenland's timekeeping practice on 2024-03-31, by
changing its time zone from -01/+00 to -02/-01 at the same moment
as the spring-forward transition. Its clocks will therefore not
spring forward as previously scheduled. The time zone change
reverts to its common practice before 1981.
Fix predictions for DST transitions in Palestine in 2072-2075,
correcting a typo introduced in 2023a.
Changes to past and future timestamps
Vostok, Antarctica changed to +05 on 2023-12-18. It had been at
+07 (not +06) for years. (Thanks to Zakhary V. Akulov.)
Change data for Casey, Antarctica to agree with timeanddate.com,
by adding five time zone changes since 2020. Casey is now at +08
instead of +11.
Changes to past tm_isdst flags
Much of Greenland, represented by America/Nuuk, changed its
standard time from -03 to -02 on 2023-03-25, not on 2023-10-28.
This does not affect UTC offsets, only the tm_isdst flag.
(Thanks to Thomas M. Steenholdt.)
New data file
A new data file zonenow.tab helps configure applications that use
timestamps dated from now on. This simplifies configuration,
since users choose from a smaller Zone set. The file's format is
experimental and subject to change.
Changes to code
localtime.c no longer mishandles TZif files that contain a single
transition into a DST regime. Previously, it incorrectly assumed
DST was in effect before the transition too. (Thanks to Alois
Treindl for debugging help.)
localtime.c's timeoff no longer collides with OpenBSD 7.4.
The C code now uses _Generic only if __STDC_VERSION__ says the
compiler is C11 or later.
tzselect now optionally reads zonenow.tab, to simplify when
configuring only for timestamps dated from now on.
tzselect no longer creates temporary files.
tzselect no longer mishandles the following:
Spaces and most other special characters in BUGEMAIL, PACKAGE,
TZDIR, and VERSION.
TZ strings when using mawk 1.4.3, which mishandles regular
expressions of the form /X{2,}/.
ISO 6709 coordinates when using an awk that lacks the GNU
extension of newlines in -v option-arguments.
Non UTF-8 locales when using an iconv command that lacks the GNU
//TRANSLIT extension.
zic no longer mishandles data for Palestine after the year 2075.
Previously, it incorrectly omitted post-2075 transitions that are
predicted for just before and just after Ramadan. (Thanks to Ken
Murchison for debugging help.)
zic now works again on Linux 2.6.16 and 2.6.17 (2006).
(Problem reported by Rune Torgersen.)
Changes to build procedure
The Makefile is now more compatible with POSIX:
* It no longer defines AR, CC, CFLAGS, LDFLAGS, and SHELL.
* It no longer uses its own 'cc' in place of CC.
* It now uses ARFLAGS, with default specified by POSIX.
* It does not use LFLAGS incompatibly with POSIX.
* It uses the special .POSIX target.
* It quotes special characters more carefully.
* It no longer mishandles builds in an ISO 8859 locale.
Due to the CC changes, TZDIR is now #defined in a file tzfile.h
built by 'make', not in a $(CC) -D option. Also, TZDEFAULT is
now treated like TZDIR as they have similar roles.
Changes to commentary
Limitations and hazards of the optional support for obsolescent
C89 platforms are documented better, along with a tentative
schedule for removing this support.
Release 2023c - 2023-03-28 12:42:14 -0700
Changes to past and future timestamps
Model Lebanon's DST chaos by reverting data to tzdb 2023a.
(Thanks to Rany Hany for the heads-up.)
Release 2023b - 2023-03-23 19:50:38 -0700
Changes to future timestamps
This year Lebanon springs forward April 20/21 not March 25/26.
(Thanks to Saadallah Itani.) [This was reverted in 2023c.]
Release 2023a - 2023-03-22 12:39:33 -0700
Briefly:
Egypt now uses DST again, from April through October.
This year Morocco springs forward April 23, not April 30.
Palestine delays the start of DST this year.
Much of Greenland still uses DST from 2024 on.
America/Yellowknife now links to America/Edmonton.
tzselect can now use current time to help infer timezone.
The code now defaults to C99 or later.
Fix use of C23 attributes.
Changes to future timestamps
Starting in 2023, Egypt will observe DST from April's last Friday
through October's last Thursday. (Thanks to Ahmad ElDardiry.)
Assume the transition times are 00:00 and 24:00, respectively.
In 2023 Morocco's spring-forward transition after Ramadan
will occur April 23, not April 30. (Thanks to Milamber.)
Adjust predictions for future years accordingly. This affects
predictions for 2023, 2031, 2038, and later years.
This year Palestine will delay its spring forward from
March 25 to April 29 due to Ramadan. (Thanks to Heba Hamad.)
Make guesses for future Ramadans too.
Much of Greenland, represented by America/Nuuk, will continue to
observe DST using European Union rules. When combined with
Greenland's decision not to change the clocks in fall 2023,
America/Nuuk therefore changes from -03/-02 to -02/-01 effective
2023-10-29 at 01:00 UTC. (Thanks to Thomas M. Steenholdt.)
This change from 2022g doesn't affect timestamps until 2024-03-30,
and doesn't affect tm_isdst until 2023-03-25.
Changes to past timestamps
America/Yellowknife has changed from a Zone to a backward
compatibility Link, as it no longer differs from America/Edmonton
since 1970. (Thanks to Almaz Mingaleev.) This affects some
pre-1948 timestamps. The old data are now in 'backzone'.
Changes to past time zone abbreviations
When observing Moscow time, Europe/Kirov and Europe/Volgograd now
use the abbreviations MSK/MSD instead of numeric abbreviations,
for consistency with other timezones observing Moscow time.
Changes to code
You can now tell tzselect local time, to simplify later choices.
Select the 'time' option in its first prompt.
You can now compile with -DTZNAME_MAXIMUM=N to limit time zone
abbreviations to N bytes (default 255). The reference runtime
library now rejects POSIX-style TZ strings that contain longer
abbreviations, treating them as UTC. Previously the limit was
platform dependent and abbreviations were silently truncated to
16 bytes even when the limit was greater than 16.
The code by default is now designed for C99 or later. To build on
a mostly-C89 platform, compile with -DPORT_TO_C89; this should
work on C89 platforms that also support C99 'long long' and
perhaps a few other extensions to C89. To support C89 callers of
tzcode's library, compile with -DSUPPORT_C89; however, this could
trigger latent bugs in C99-or-later callers. The two new macros
are transitional aids planned to be removed in a future version
(say, in 2029), when C99 or later will be required.
The code now builds again on pre-C99 platforms, if you compile
with -DPORT_TO_C89. This fixes a bug introduced in 2022f.
On C23-compatible platforms tzcode no longer uses syntax like
'static [[noreturn]] void usage(void);'. Instead, it uses
'[[noreturn]] static void usage(void);' as strict C23 requires.
(Problem reported by Houge Langley.)
The code's functions now constrain their arguments with the C
'restrict' keyword consistently with their documentation.
This may allow future optimizations.
zdump again builds standalone with ckdadd and without setenv,
fixing a bug introduced in 2022g. (Problem reported by panic.)
leapseconds.awk can now process a leap seconds file that never
expires; this might be useful if leap seconds are discontinued.
Changes to commentary
tz-link.html has a new section "Coordinating with governments and
distributors". (Thanks to Neil Fuller for some of the text.)
To improve tzselect diagnostics, zone1970.tab's comments column is
now limited to countries that have multiple timezones.
Note that leap seconds are planned to be discontinued by 2035.
Release 2022g - 2022-11-29 08:58:31 -0800
Briefly:
The northern edge of Chihuahua changes to US timekeeping.
Much of Greenland stops changing clocks after March 2023.
Fix some pre-1996 timestamps in northern Canada.
C89 is now deprecated; please use C99 or later.
Portability fixes for AIX, libintl, MS-Windows, musl, z/OS
In C code, use more C23 features if available.
C23 timegm now supported by default
Fixes for unlikely integer overflows
Changes to future timestamps
In the Mexican state of Chihuahua, the border strip near the US
will change to agree with nearby US locations on 2022-11-30.
The strip's western part, represented by Ciudad Juárez, switches
from -06 all year to -07/-06 with US DST rules, like El Paso, TX.
The eastern part, represented by Ojinaga, will observe US DST next
year, like Presidio, TX. (Thanks to Heitor David Pinto.)
A new Zone America/Ciudad_Juarez splits from America/Ojinaga.
Much of Greenland, represented by America/Nuuk, stops observing
winter time after March 2023, so its daylight saving time becomes
standard time. (Thanks to Jonas Nyrup and Jürgen Appel.)
Changes to past timestamps
Changes for pre-1996 northern Canada (thanks to Chris Walton):
Merge America/Iqaluit and America/Pangnirtung into the former,
with a backward compatibility link for the latter name.
There is no good evidence the two locations differ since 1970.
This change affects pre-1996 America/Pangnirtung timestamps.
Cambridge Bay, Inuvik, Iqaluit, Rankin Inlet, Resolute and
Yellowknife did not observe DST in 1965, and did observe DST
from 1972 through 1979.
Whitehorse moved from -09 to -08 on 1966-02-27, not 1967-05-28.
Colombia's 1993 fallback was 02-06 24:00, not 04-04 00:00.
(Thanks to Alois Treindl.)
Singapore's 1981-12-31 change was at 16:00 UTC (23:30 local time),
not 24:00 local time. (Thanks to Geoff Clare via Robert Elz.)
Changes to code
Although tzcode still works with C89, bugs found in recent routine
maintenance indicate that bitrot has set in and that in practice
C89 is no longer used to build tzcode. As it is a maintenance
burden, support for C89 is planned to be removed soon. Instead,
please use compilers compatible with C99, C11, C17, or C23.
timegm, which tzcode implemented in 1989, will finally be
standardized 34 years later as part of C23, so timegm is now
supported even if STD_INSPIRED is not defined.
Fix bug in zdump's tzalloc emulation on hosts that lack tm_zone.
(Problem reported by Đoàn Trần Công Danh.)
Fix bug in zic on hosts where malloc(0) yields NULL on success.
(Problem reported by Tim McBrayer for AIX 6.1.)
Fix zic configuration to avoid linkage failures on some platforms.
(Problems reported by Gilmore Davidson and Igor Ivanov.)
Work around MS-Windows nmake incompatibility with POSIX.
(Problem reported by Manuela Friedrich.)
Port mktime and strftime to debugging platforms where accessing
uninitialized data has undefined behavior (strftime problem
reported by Robert Elz).
Check more carefully for unlikely integer overflows, preferring
C23 <stdckdint.h> to overflow checking by hand, as the latter has
had obscure bugs.
Changes to build procedure
New Makefile rule check_mild that skips checking whether Link
lines are in the file 'backward'. (Inspired by a suggestion from
Stephen Colebourne.)
Release 2022f - 2022-10-28 18:04:57 -0700
Briefly:
Mexico will no longer observe DST except near the US border.
Chihuahua moves to year-round -06 on 2022-10-30.
Fiji no longer observes DST.
Move links to 'backward'.
In vanguard form, GMT is now a Zone and Etc/GMT a link.
zic now supports links to links, and vanguard form uses this.
Simplify four Ontario zones.
Fix a Y2438 bug when reading TZif data.
Enable 64-bit time_t on 32-bit glibc platforms.
Omit large-file support when no longer needed.
In C code, use some C23 features if available.
Remove no-longer-needed workaround for Qt bug 53071.
Changes to future timestamps
Mexico will no longer observe DST after 2022, except for areas
near the US border that continue to observe US DST rules.
On 2022-10-30 at 02:00 the Mexican state of Chihuahua moves
from -07 (-06 with DST) to year-round -06, thus not changing
its clocks that day. The new law states that Chihuahua
near the US border no longer observes US DST.
(Thanks to gera for the heads-up about Chihuahua.)
Fiji will not observe DST in 2022/3. (Thanks to Shalvin Narayan.)
For now, assume DST is suspended indefinitely.
Changes to data
Move links to 'backward' to ease and simplify link maintenance.
This affects generated data only if you use 'make BACKWARD='.
GMT is now a Zone and Etc/GMT a link instead of vice versa,
as GMT is needed for leap second support whereas Etc/GMT is not.
However, this change exposes a bug in TZUpdater 2.3.2 so it is
present only in vanguard form for now.
Vanguard form now uses links to links, as zic now supports this.
Changes to past timestamps
Simplify four Ontario zones, as most of the post-1970 differences
seem to have been imaginary. (Problem reported by Chris Walton.)
Move America/Nipigon, America/Rainy_River, and America/Thunder_Bay
to 'backzone'; backward-compatibility links still work, albeit

Changes to code
zic now supports links to links regardless of input line order.
For example, if Australia/Sydney is a Zone, the lines
Link Australia/Canberra Australia/ACT
Link Australia/Sydney Australia/Canberra
now work correctly, even though the shell commands
ln Australia/Canberra Australia/ACT
ln Australia/Sydney Australia/Canberra
would fail because the first command attempts to use a link
Australia/Canberra that does not exist until after the second
command is executed. Previously, zic had unspecified behavior if
a Link line's target was another link, and zic often misbehaved if
a Link line's target was a later Link line.
Fix line number in zic's diagnostic for a link to a link.
Fix a bug that caused localtime to mishandle timestamps starting
in the year 2438 when reading data generated by 'zic -b fat' when
distant-future DST transitions occur at times given in standard
time or in UT, not the usual case of local time. This occurs when
the corresponding .zi Rule lines specify DST transitions with TO
columns of 'max' and AT columns that end in 's' or 'u'. The
number 2438 comes from the 32-bit limit in the year 2038, plus the
400-year Gregorian cycle. (Problem reported by Bradley White.)
On glibc 2.34 and later, which optionally supports 64-bit time_t
on platforms like x86 where time_t was traditionally 32 bits,
default time_t to 64 instead of 32 bits. This lets functions like
localtime support timestamps after the year 2038, and fixes
year-2038 problems in zic when accessing files dated after 2038.
To continue to limit time_t to 32 bits on these platforms, use
"make CFLAGS='-D_TIME_BITS=32'".
In C code, do not enable large-file support on platforms like AIX
and macOS that no longer need it now that tzcode does not use
off_t or related functions like 'stat'. Large-file support is
still enabled by default on GNU/Linux, as it is needed for 64-bit
time_t support.
In C code, prefer C23 keywords to pre-C23 macros for alignof,
bool, false, and true. Also, use the following C23 features if
available: __has_include, unreachable.
zic no longer works around Qt bug 53071, as the relevant Qt
releases have been out of support since 2019. This change affects
only fat TZif files, as thin files never had the workaround.
zdump no longer modifies the environ vector when compiled on
platforms lacking tm_zone or when compiled with -DUSE_LTZ=0.
This avoid undefined behavior on POSIX platforms.

# Vostok, which is one of the Russian stations, is set on the same
# time as Moscow, Russia.
#
# From Lee Hotz (2001-03-08):
# I queried the folks at Columbia who spent the summer at Vostok and this is
# what they had to say about time there:
# "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
# of GMT). This is a time zone I think two hours east of Moscow. The
# natural time zone is in between the two: 8 hours ahead of GMT."
#
# From Paul Eggert (2001-05-04):
# This seems to be hopelessly confusing, so I asked Lee Hotz about it
# in person. He said that some Antarctic locations set their local
# time so that noon is the warmest part of the day, and that this
# changes during the year and does not necessarily correspond to mean
# solar noon. So the Vostok time might have been whatever the clocks
# happened to be during their visit. So we still don't really know what time
# it is at Vostok.
#
# From Zakhary V. Akulov (2023-12-17 22:00:48 +0700):
# ... from December, 18, 2023 00:00 by my decision the local time of
# the Antarctic research base Vostok will correspond to UTC+5.
# (2023-12-19): We constantly interact with Progress base, with company who
# builds new wintering station, with sledge convoys, with aviation - they all
# use UTC+5. Besides, difference between Moscow time is just 2 hours now, not 4.
# (2023-12-19, in response to the question "Has local time at Vostok
# been UTC+6 ever since 1957, or has it changed before?"): No. At least
# since my antarctic career start, 10 years ago, Vostok base has UTC+7.
# (In response to a 2023-12-18 question "from 02:00 to 00:00 today"): This.

# From Saadallah Itani (2023-03-23):
# Lebanon ... announced today delay of Spring forward from March 25 to April 20.
#
# From Paul Eggert (2023-03-27):
# This announcement was by the Lebanese caretaker prime minister Najib Mikati.
# https://www.mtv.com.lb/en/News/Local/1352516/lebanon-postpones-daylight-saving-time-adoption
# A video was later leaked to the media of parliament speaker Nabih Berri
# asking Mikati to postpone DST to aid observance of Ramadan, Mikati objecting
# that this would cause problems such as scheduling airline flights, to which
# Berri interjected, "What flights?"
#
# The change was controversial and led to a partly-sectarian divide.
# Many Lebanese institutions, including the education ministry, the Maronite
# church, and two news channels LCBI and MTV, ignored the announcement and
# went ahead with the long-scheduled spring-forward on March 25/26, some
# arguing that the prime minister had not followed the law because the change
# had not been approved by the cabinet. Google went with the announcement;
# Apple ignored it. At least one bank followed the announcement for its doors,
# but ignored the announcement in internal computer systems.
# Beirut international airport listed two times for each departure.
# Dan Azzi wrote "My view is that this whole thing is a Dumb and Dumber movie."
# Eventually the prime minister backed down, said the cabinet had decided to
# stick with its 1998 decision, and that DST would begin midnight March 29/30.
# https://www.nna-leb.gov.lb/en/miscellaneous/604093/lebanon-has-two-times-of-day-amid-daylight-savings
# https://www.cnbc.com/2023/03/27/lebanon-in-two-different-time-zones-as-government-disagrees-on-daylight-savings.html
#
# Although we could model the chaos with two Zones, that would likely cause
# more trouble than it would cure. Since so many manual clocks and
# computer-based timestamps ignored the announcement, stick with official
# cabinet resolutions in the data while recording the prime minister's
# announcement as a comment. This is how we treated a similar situation in
# Rio de Janeiro in spring 1993.

# For now, guess that spring and fall transitions will normally
# continue to use 2022's rules, that during DST Palestine will switch
# to standard time at 02:00 the last Saturday before Ramadan and back
# to DST at 02:00 the first Saturday after Ramadan, and that
# if the normal spring-forward or fall-back transition occurs during
# Ramadan the former is delayed and the latter advanced.
# To implement this, I predicted Ramadan-oriented transition dates for
# 2023 through 2086 by running the following program under GNU Emacs 28.2,
# with the results integrated by hand into the table below.
# Predictions after 2086 are approximated without Ramadan.

# an international standard, there are some places on the high seas where the
# correct date is ambiguous.
# From Wikipedia <https://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
# Before 1920, all ships kept local apparent time on the high seas by setting
# their clocks at night or at the morning sight so that, given the ship's
# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
# meridian (12 o'clock = local apparent noon). During 1917, at the
# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
# ships, both military and civilian, should adopt hourly standard time zones
# on the high seas. Whenever a ship was within the territorial waters of any
# nation it would use that nation's standard time. The captain was permitted
# to change his ship's clocks at a time of his choice following his ship's
# entry into another zone time - he often chose midnight. These zones were
# adopted by all major fleets between 1920 and 1925 but not by many
# independent merchant ships until World War II.
# From Wikipedia <https://en.wikipedia.org/wiki/Nautical_time> (2023-01-23):
# The nautical time zone system is analogous to the terrestrial time zone
# system for use on high seas. Under the system time changes are required for
# changes of longitude in one-hour steps. The one-hour step corresponds to a
# time zone width of 15° longitude. The 15° gore that is offset from GMT or
# UT1 (not UTC) by twelve hours is bisected by the nautical date line into two
# 7°30' gores that differ from GMT by ±12 hours. A nautical date line is
# implied but not explicitly drawn on time zone maps. It follows the 180th
# meridian except where it is interrupted by territorial waters adjacent to
# land, forming gaps: it is a pole-to-pole dashed line.
# From Paul Eggert, using references suggested by Oscar van Vlijmen
# (2005-03-20):
#
# The American Practical Navigator (2002)
# http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187
# talks only about the 180-degree meridian with respect to ships in
# international waters; it ignores the international date line.
# From Paul Eggert (2023-01-23):
# The American Practical Navigator <https://msi.nga.mil/Publications/APN>,
# 2019 edition, merely says that the International Date Line
# "coincides with the 180th meridian over most of its length."

# This has made for an interesting situation there, which warranted the news.
# No one there that I spoke with seems concerned, or has plans to

# really interfere with any activities or make things difficult locally.
# They plan to celebrate New Year's turn-over twice, one hour apart,

# 2. The shift *from* DST in 2023 happens as normal, but coincides with the

# From Steffen Thorsen (2001-05-01):
# Although I could not find it explicitly, it seems that Jan Mayen and

# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan

# <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
# for normal/standard time in Norway is from 1894-06-29 no 1 (came

# part of this law since 1925/1930. (From
# <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
# able to find if Jan Mayen used a different time zone (e.g. -0100)
# before 1930. Jan Mayen has only been "inhabited" since 1921 by
# Norwegian meteorologists and maybe used the same time as Norway ever
# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
# before 1895, and therefore probably changed the local time somewhere
# between 1895 and 1925 (inclusive).
# From Paul Eggert (2013-09-04):

# From Paul Eggert (2023-09-06):
# This file contains a table of two-letter country codes. Columns are
# separated by a single tab. Lines beginning with '#' are comments.
# All text uses UTF-8 encoding. The columns of the table are as follows:
#
# 1. ISO 3166-1 alpha-2 country code, current as of
# ISO 3166-1 N976 (2018-11-06). See: Updates on ISO 3166-1
# https://isotc.iso.org/livelink/livelink/Open/16944257
# 2. The usual English name for the coded region,
# chosen so that alphabetic sorting of subsets produces helpful lists.
# This is not the same as the English name in the ISO 3166 tables.
# ISO/TC 46 N1108 (2023-04-05). See: ISO/TC 46 Documents
# https://www.iso.org/committee/48750.html?view=documents
# 2. The usual English name for the coded region. This sometimes
# departs from ISO-listed names, sometimes so that sorted subsets
# of names are useful (e.g., "Samoa (American)" and "Samoa
# (western)" rather than "American Samoa" and "Samoa"),
# sometimes to avoid confusion among non-experts (e.g.,
# "Czech Republic" and "Turkey" rather than "Czechia" and "Türkiye"),
# and sometimes to omit needless detail or churn (e.g., "Netherlands"
# rather than "Netherlands (the)" or "Netherlands (Kingdom of the)").
#
# The table is sorted by country code.

# tzdb timezone descriptions, for users who do not care about old timestamps
#
# This file is in the public domain.
#
# From Paul Eggert (2023-12-18):
# This file contains a table where each row stands for a timezone
# where civil timestamps are predicted to agree from now on.
# This file is like zone1970.tab (see zone1970.tab's coments),
# but with the following changes:
#
# 1. Each timezone corresponds to a set of clocks that are planned
# to agree from now on. This is a larger set of clocks than in
# zone1970.tab, where each timezone's clocks must agree from 1970 on.
# 2. The first column is irrelevant and ignored.
# 3. The table is sorted in a different way:
# first by standard time UTC offset;
# then, if DST is used, by daylight saving UTC offset;
# then by time zone abbreviation.
# 4. Every timezone has a nonempty comments column, with wording
# distinguishing the timezone only from other timezones with the
# same UTC offset at some point during the year.
#
# The format of this table is experimental, and may change in future versions.
#
# This table is intended as an aid for users, to help them select timezones
# appropriate for their practical needs. It is not intended to take or
# endorse any position on legal or territorial claims.
