+
+ 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 VulaÅ? 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.)
+

+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).
