Release 20198 - 2019-03-25 22:01:33 -0700
Release 2019c - 2019-09-11 08:59:48 -0700
Briefly:
Fiji observes DST from 2019-11-10 to 2020-01-12.
Norfolk Island starts observing Australian-style DST.
Changes to future timestamps
Fiji's next DST transitions will be 2019-11-10 and 2020-01-12
instead of 2019-11-03 and 2020-01-19. (Thanks to Raymond Kumar.)
Adjust future guesses accordingly.
Norfolk Island will observe Australian-style DST starting in
spring 2019. The first transition is on 2019-10-06. (Thanks to
Kyle Czech and Michael Deckers.)
Changes to past timestamps
Many corrections to time in Turkey from 1940 through 1985.
(Thanks to Oya Vulaş via Alois Treindl, and to Kıvanç Yazan.)
The Norfolk Island 1975-03-02 transition was at 02:00 standard
time, not 02:00 DST. (Thanks to Michael Deckers.)
South Korea observed DST from 1948 through 1951. Although this
info was supposed to appear in release 2014j, a typo inadvertently
suppressed the change. (Thanks to Alois Treindl.)
Detroit observed DST in 1967 and 1968 following the US DST rules,
except that its 1967 DST began on June 14 at 00:01. (Thanks to
Alois Treindl for pointing out that the old data entries were
probably wrong.)
Fix several errors in pre-1970 transitions in Perry County, IN.
(Thanks to Alois Triendl for pointing out the 1967/9 errors.)
Edmonton did not observe DST in 1967 or 1969. In 1946 Vancouver
ended DST on 09-29 not 10-13, and Vienna ended DST on 10-07 not
10-06. In 1945 Königsberg (now Kaliningrad) switched from +01/+02
to +02/+03 on 04-10 not 01-01, and its +02/+03 is abbreviated
EET/EEST, not CET/CEST. (Thanks to Alois Triendl.) In 1946
Königsberg switched to +03 on 04-07 not 01-01.
In 1946 Louisville switched from CST to CDT on 04-28 at 00:01, not
01-01 at 00:00. (Thanks to Alois Treindl and Michael Deckers.)
Also, it switched from CST to CDT on 1950-04-30, not 1947-04-27.
The 1892-05-01 transition in Brussels was at 00:17:30, not at noon.
(Thanks to Michael Deckers.)
Changes to past time zone abbreviations and DST flags
Hong Kong Winter Time, observed from 1941-10-01 to 1941-12-25,
is now flagged as DST and is abbreviated HKWT not HKT.
Changes to code
leapseconds.awk now relies only on its input data, rather than
also relying on its comments. (Inspired by code from Dennis
Ferguson and Chris Woodbury.)
The code now defends against CRLFs in leap-seconds.list.
(Thanks to Brian Inglis and Chris Woodbury.)
Changes to documentation and commentary
theory.html discusses leap seconds. (Thanks to Steve Summit.)
Nashville's newspapers dueled about the time of day in the 1950s.
(Thanks to John Seigenthaler.)
Liechtenstein observed Swiss DST in 1941/2.
(Thanks to Alois Treindl.)
Release 2019b - 2019-07-01 00:09:53 -0700
Briefly:
Brazil no longer observes DST.
'zic -b slim' outputs smaller TZif files; please try it out.
Palestine's 2019 spring-forward transition was on 03-29, not 03-30.
Changes to future timestamps
Brazil has canceled DST and will stay on standard time indefinitely.
(Thanks to Steffen Thorsen, Marcus Diniz, and Daniel Soares de
Oliveira.)
Predictions for Morocco now go through 2087 instead of 2037, to
work around a problem on newlib when using TZif files output by
zic 2019a or earlier. (Problem reported by David Gauchard.)
Changes to past and future timestamps
Palestine's 2019 spring transition was 03-29 at 00:00, not 03-30
at 01:00. (Thanks to Sharef Mustafa and Even Scharning.) Guess
future transitions to be March's last Friday at 00:00.
Changes to past timestamps
Hong Kong's 1941-06-15 spring-forward transition was at 03:00, not
03:30. Its 1945 transition from JST to HKT was on 11-18 at 02:00,
not 09-15 at 00:00. In 1946 its spring-forward transition was on
04-21 at 00:00, not the previous day at 03:30. From 1946 through
1952 its fall-back transitions occurred at 04:30, not at 03:30.
In 1947 its fall-back transition was on 11-30, not 12-30.
(Thanks to P Chan.)
Changes to past time zone abbreviations
Italy's 1866 transition to Rome Mean Time was on December 12, not
September 22. This affects only the time zone abbreviation for
Europe/Rome between those dates. (Thanks to Stephen Trainor and
Luigi Rosa.)
Changes affecting metadata only
Add info about the Crimea situation in zone1970.tab and zone.tab.
(Problem reported by Serhii Demediuk.)
Changes to code
zic's new -b option supports a way to control data bloat and to
test for year-2038 bugs in software that reads TZif files.
'zic -b fat' and 'zic -b slim' generate larger and smaller output;
for example, changing from fat to slim shrinks the Europe/London
file from 3648 to 1599 bytes, saving about 56%. Fat and slim
files represent the same set of timestamps and use the same TZif
format as documented in tzfile(5) and in Internet RFC 8536.
Fat format attempts to work around bugs or incompatibilities in
older software, notably software that mishandles 64-bit TZif data
or uses obsolete TZ strings like "EET-2EEST" that lack DST rules.
Slim format is more efficient and does not work around 64-bit bugs
or obsolete TZ strings. Currently zic defaults to fat format
unless you compile with -DZIC_BLOAT_DEFAULT=\"slim\"; this
out-of-the-box default is intended to change in future releases
as the buggy software often mishandles timestamps anyway.
zic no longer treats a set of rules ending in 2037 specially.
Previously, zic assumed that such a ruleset meant that future
timestamps could not be predicted, and therefore omitted a
POSIX-like TZ string in the TZif output. The old behavior is no
longer needed for current tzdata, and caused problems with newlib
when used with older tzdata (reported by David Gauchard).
zic no longer generates some artifact transitions. For example,
Europe/London no longer has a no-op transition in January 1996.
Changes to build procedure
tzdata.zi now assumes zic 2017c or later. This shrinks tzdata.zi
by a percent or so.
Changes to documentation and commentary
The Makefile now documents the POSIXRULES macro as being obsolete,
and similarly, zic's -p POSIXRULES option is now documented as
being obsolete. Although the POSIXRULES feature still exists and
works as before, in practice it is rarely used for its intended
purpose, and it does not work either in the default reference
implementation (for timestamps after 2037) or in common
implementations such as GNU/Linux (for contemporary timestamps).
Since POSIXRULES was designed primarily as a temporary transition
facility for System V platforms that died off decades ago, it is
being decommissioned rather than institutionalized.
New info on Bonin Islands and Marcus (thanks to Wakaba and Phake Nick).

# Bonin (Ogasawara) Islands and Marcus Island (Minami-Tori-shima)
# From Wakaba (2019-01-28) via Phake Nick:
# National Diet Library of Japan has several reports by Japanese Government
# officers that describe the time used in islands when they visited there.
# According to them (and other sources such as newspapers), standard time UTC
# + 10 (JST + 1) and DST UTC + 11 (JST + 2) was used until its return to Japan
# at 1968-06-26 00:00 JST. The exact periods of DST are still unknown.
# I guessed Guam, Mariana, and Bonin and Marcus districts might have
# synchronized their DST periods, but reports imply they had their own
# decisions, i.e. there were three or more different time zones....
#
# https://wiki.suikawiki.org/n/小笠原諸島の標準時
# From Phake Nick (2019-02-12):
# Because their last time change to return to Japanese time when they returned
# to Japanese rule was right before 1970, ... per the current tz database
# rule, the information doesn't warrant creation of a new timezone for Bonin
# Islands itself and is thus as an anecdotal note for interest purpose only.
# ... [The abovementioned link] described some special timekeeping phenomenon
# regarding Marcus island, another remote island currently owned by Japanese

# See Asia/Ho_Chi_Minh for the source for most of this data. Also, guess
# (1) Cambodia reverted to UT +07 on 1945-09-02, when Vietnam did, and
# (2) they also reverted to +07 on 1953-11-09, the date of independence.
# These guesses are probably wrong but they're better than guessing no
# transitions there.
# From an adoptive daughter of the late Cambodian ruler Prince Sihanouk,
# via Alois Treindl (2019-08-08):
#
# King Sihanouk said that, during the Japanese occupation, starting with
# what historians refer to as "le coup de force du 9 mars 1945", Cambodia,
# like the entire French Indochina, used Tokyo time zone. After Japan
# surrendered, 2 September 1945, Cambodia fell under French rule again and
# adopted Hanoi time zone again.
#
# However, on 7 January 1946, Sihanouk and Tioulong managed to obtain a
# status of "internal autonomy" from the government of Charles de Gaulle.
# Although many fields remained under the administration of the French
# (customs, taxes, justice, defence, foreign affairs, etc.), the Cambodian
# administration was responsible for religious matters and traditional
# celebrations, which included our calendar and time. The time zone was GMT
# + 7 and _no_ DST was applied.
#
# After Sihanouk and Tioulong achieved full independence, on 9 November 1953,
# GMT + 7 was maintained.

# In early November 1914, the Germans imposed the time zone used in central
# Europe and forced the inhabitants to set their watches and public clocks
# sixty minutes ahead. Many were reluctant to accept "German time" and
# continued to use "Belgian time" among themselves. Reflecting the spirit of
# resistance that arose in the population, a song made fun of this change....
# The song ended:
# Putting your clock forward
# Will but hasten the happy hour
# When we kick out the Boches!

# This decision changes the default longitude for Turkish time zone from 30

# to +3. This is published & applied on 1978-06-29. At that time, Turkey was
# already on summer time (already on 45E). Hence, this new law just meant an
# "continuous summer time". Note that this was reversed in a few years.

# Assume this practice predates 1970, so Fort Pierre can use America/Chicago.
# From Paul Eggert (2015-04-06):
# In 1950s Nashville a public clock had dueling faces, one for conservatives
# and the other for liberals; the two sides didn't agree about the time of day.
# I haven't found a photo of this clock, nor have I tracked down the TIME
# magazine report cited below, but here's the story as told by the late
# American journalist John Seigenthaler, who was there:
#
# "The two [newspaper] owners held strongly contrasting political and
# ideological views. Evans was a New South liberal, Stahlman an Old South
# conservative, and their two papers frequently clashed editorially, often on
# the same day.... In the 1950s as the state legislature was grappling with
# the question of whether to approve daylight saving time for the entire state,
# TIME magazine reported:
#
# "'The Nashville Banner and The Nashville Tennessean rarely agree on anything
# but the time of day - and last week they couldn't agree on that.'
#
# "It was all too true. The clock on the front of the building had two faces -
# The Tennessean side of the building facing west, the other, east. When it
# was high noon Banner time, it was 11 a.m. Tennessean time."
#
# Seigenthaler J. For 100 years, Tennessean had it covered.

# one hour in 1914." This change is not in Shanks. We have no more
# info, so omit this for now.
#
# From Paul Eggert (2017-07-26):
# Although Shanks says Detroit observed DST in 1967 from 06-14 00:01
# until 10-29 00:01, I now see multiple reports that this is incorrect.
# For example, according to a 50-year anniversary report about the 1967
# Detroit riots and a major-league doubleheader on 1967-07-23, "By the time
# the last fly ball of the doubleheader settled into the glove of leftfielder
# Lenny Green, it was after 7 p.m. Detroit did not observe daylight saving
# time, so light was already starting to fail. Twilight was made even deeper
# by billowing columns of smoke that ascended in an unbroken wall north of the
# ballpark." See: Dow B. Detroit '67: As violence unfolded, Tigers played two
# at home vs. Yankees. Detroit Free Press 2017-07-23.
# https://www.freep.com/story/sports/mlb/tigers/2017/07/23/detroit-tigers-1967-riot-new-york-yankees/499951001/
# From Paul Eggert (2019-07-06):
# Due to a complicated set of legal maneuvers, in 1967 Michigan did
# not start daylight saving time when the rest of the US did.
# Instead, it began DST on Jun 14 at 00:01. This was big news:
# the Detroit Free Press reported it at the top of Page 1 on
# 1967-06-14, in an article "State Adjusting to Switch to Fast Time"
# by Gary Blonston, above an article about Thurgood Marshall's
# confirmation to the US Supreme Court. Although Shanks says Detroit
# observed DST until 1967-10-29 00:01, that time of day seems to be
# incorrect, as the Free Press later said DST ended in Michigan at the
# same time as the rest of the US. Also, although Shanks reports no DST in
# Detroit in 1968, it did observe DST that year; in the November 1968
# election Michigan voters narrowly repealed DST, effective 1969.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.

# There was no DST in Alberta in 1967... Calgary Herald, 29 April 1967.
# 1969, no DST, from Edmonton Journal 18 April 1969

# From Paul Eggert (2019-07-25):
# Pearce's book says that Alberta's 1948 Daylight Saving Act required
# Mountain Standard Time without DST, and that "anyone who broke that law
# could be fined up to $25 and costs". There seems to be no record of
# anybody paying the fine. The law was not changed until an August 1971
# plebiscite reinstituted DST in 1972. This story is also mentioned in:

<h2 id="leapsec">Leap seconds</h2>
<p>
The <code><abbr>tz</abbr></code> code and data can account for leap seconds,
thanks to code contributed by Bradley White.
However, the leap second support of this package is rarely used directly
because POSIX requires leap seconds to be excluded and many
software packages would mishandle leap seconds if they were present.
Instead, leap seconds are more commonly handled by occasionally adjusting
the operating system kernel clock as described in
<a href="tz-link.html#precision">Precision timekeeping</a>,
and this package by default installs a <samp>leapseconds</samp> file
commonly used by
<a href="http://www.ntp.org"><abbr title="Network Time Protocol">NTP</abbr></a>
software that adjusts the kernel clock.
However, kernel-clock twiddling approximates UTC only roughly,
and systems needing more-precise UTC can use this package's leap
second support directly.
</p>
<p>
The directly-supported mechanism assumes that <code>time_t</code>
counts of seconds since the POSIX epoch normally include leap seconds,
as opposed to POSIX <code>time_t</code> counts which exclude leap seconds.
This modified timescale is converted to <abbr>UTC</abbr>
at the same point that time zone and DST adjustments are applied &ndash;
namely, at calls to <code>localtime</code> and analogous functions &ndash;
and the process is driven by leap second information
stored in alternate versions of the <abbr>TZif</abbr> files.
Because a leap second adjustment may be needed even
if no time zone correction is desired,
calls to <code>gmtime</code>-like functions
also need to consult a <abbr>TZif</abbr> file,
conventionally named <samp><abbr>GMT</abbr></samp>,
to see whether leap second corrections are needed.
To convert an application's <code>time_t</code> timestamps to or from
POSIX <code>time_t</code> timestamps (for use when, say,
embedding or interpreting timestamps in portable
<a href="https://en.wikipedia.org/wiki/Tar_(computing)"><code>tar</code></a>
files),
the application can call the utility functions
<code>time2posix</code> and <code>posix2time</code>
included with this package.
</p>
<p>
If the POSIX-compatible <abbr>TZif</abbr> file set is installed
in a directory whose basename is <samp>zoneinfo</samp>, the
leap-second-aware file set is by default installed in a separate
directory <samp>zoneinfo-leaps</samp>.
Although each process can have its own time zone by setting
its <code>TZ</code> environment variable, there is no support for some
processes being leap-second aware while other processes are
POSIX-compatible; the leap-second choice is system-wide.
So if you configure your kernel to count leap seconds, you should also
discard <samp>zoneinfo</samp> and rename <samp>zoneinfo-leaps</samp>
to <samp>zoneinfo</samp>.
Alternatively, you can install just one set of <abbr>TZif</abbr> files
in the first place; see the <code>REDO</code> variable in this package's
<a href="https://en.wikipedia.org/wiki/Makefile">makefile</a>.
