Release 2020f - 2020-12-29 00:17:46 -0800 Change to build procedure 'make rearguard_tarballs' no longer generates a bad rearguard.zi, fixing a 2020e bug. (Problem reported by Deborah Goldsmith.)

Briefly: Volgograd switches to Moscow time on 2020-12-27 at 02:00. Changes to future timestamps Volgograd changes time zone from +04 to +03 on 2020-12-27 at 02:00. (Thanks to Alexander Krivenyshev and Stepan Golosunov.) Changes to past timestamps Correct many pre-1986 transitions, fixing entries originally derived from Shanks. The fixes include: - Australia: several 1917 through 1971 transitions - Bahamas: several 1941 through 1945 transitions - Bermuda: several 1917 through 1956 transitions - Belize: several 1942 through 1968 transitions - Ghana: several 1915 through 1956 transitions - Israel and Palestine: several 1940 through 1985 transitions - Kenya and adjacent: several 1908 through 1960 transitions - Nigeria and adjacent: correcting LMT in Lagos, and several 1905 through 1919 transitions - Seychelles: the introduction of standard time in 1907, not 1906 - Vanuatu: DST in 1973-1974, and a corrected 1984 transition (Thanks to P Chan.) Because of the Australia change, Australia/Currie (King Island) is no longer needed, as it is identical to Australia/Hobart for all timestamps since 1970 and was therefore created by mistake. Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file. Changes to past time zone abbreviations and DST flags To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01. (Thanks to P Chan.) Changes to documentation The zic man page now documents zic's coalescing of transitions when a zone falls back just before DST springs forward.

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). (From OE-Core rev: bbbb985808e5c301cdb7fdb1ff677706e99b4785) Signed-off-by: Armin Kuster Signed-off-by: Richard Purdie

timezone: update to 2019a

2019-03-29T08:28:53+00:00

The 2019a release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Briefly: Palestine "springs forward" on 2019-03-30 instead of 2019-03-23. Metlakatla "fell back" to rejoin Alaska Time on 2019-01-20 at 02:00. Changes to past and future timestamps Palestine will not start DST until 2019-03-30, instead of 2019-03-23 as previously predicted. Adjust our prediction by guessing that spring transitions will be between 24 and 30 March, which matches recent practice since 2016. (Thanks to Even Scharning and Tim Parenti.) Metlakatla ended its observance of Pacific standard time, rejoining Alaska Time, on 2019-01-20 at 02:00. (Thanks to Ryan Stanley and Tim Parenti.) Changes to past timestamps Israel observed DST in 1980 (08-02/09-13) and 1984 (05-05/08-25). (Thanks to Alois Treindl and Isaac Starkman.) Changes to time zone abbreviations Etc/UCT is now a backward-compatibility link to Etc/UTC, instead of being a separate zone that generates the abbreviation "UCT", which nowadays is typically a typo. (Problem reported by Isiah Meadows.) Changes to code zic now has an -r option to limit the time range of output data. For example, 'zic -r @1000000000' limits the output data to timestamps starting 1000000000 seconds after the Epoch. This helps shrink output size and can be useful for applications not needing the full timestamp history, such as TZDIST truncation; see Internet RFC 8536 section 5.1. (Inspired by a feature request from Christopher Wong, helped along by bug reports from Wong and from Tim Parenti.) Changes to documentation Mention Internet RFC 8536 (February 2019), which documents TZif. tz-link.html now cites tzdata-meta .
