by Paul Eggert Jan. 5, 2019

Jan. 5, 2019

The 2018i release of the tz code and data is available. It reflects the following change, which was circulated on the tz mailing list: Briefly: São Tomé and Príncipe switches from +01 to +00 on 2019-01-01. Changes to future timestamps Due to a change in government, São Tomé and Príncipe switches back from +01 to +00 on 2019-01-01 at 02:00. (Thanks to Vadim Nasardinov and Michael Deckers.)

São Tomé and Príncipe tz change (Jan 1, 2019)
by Vadim Nasardinov Dec. 30, 2018

Dec. 30, 2018

São Tomé and Príncipe is about to do the following on Jan 1, 2019: http://www.stp-press.st/2018/12/05/governo-jesus-ja-decidiu-repor-hora-lega… “O Conselho de Ministros, relativamente a hora legal de São Tomé e Príncipe, decidiu que a partir de 1 de Janeiro de 2019 será reposta a nossa hora secular” I don't read Portuguese but this sounds like a change. Old news? I don't see any discussion of this in https://mm.icann.org/pipermail/tz/2018-December/thread.html

[tz-announce] 2018h release of tz code and data available
by Paul Eggert Dec. 29, 2018

Dec. 29, 2018

The 2018h 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: Qyzylorda, Kazakhstan moved from +06 to +05 on 2018-12-21. New zone Asia/Qostanay because Qostanay, Kazakhstan didn't move. Metlakatla, Alaska observes PST this winter only. Guess Morocco will continue to adjust clocks around Ramadan. Add predictions for Iran from 2038 through 2090. Changes to future timestamps Guess that Morocco will continue to fall back just before and spring forward just after Ramadan, the practice since 2012. (Thanks to Maamar Abdelkader.) This means Morocco will observe negative DST during Ramadan in main and vanguard formats, and in rearguard format it stays in the +00 timezone and observes ordinary DST in all months other than Ramadan. As before, extend this guesswork to the year 2037. As a consequence, Morocco is scheduled to observe three DST transitions in some Gregorian years (e.g., 2033) due to the mismatch between the Gregorian and Islamic calendars. The table of exact transitions for Iranian DST has been extended. It formerly cut off before the year 2038 in a nod to 32-bit time_t. It now cuts off before 2091 as there is doubt about how the Persian calendar will treat 2091. This change predicts DST transitions in 2038-9, 2042-3, and 2046-7 to occur one day later than previously predicted. As before, post-cutoff transitions are approximated. Changes to past and future timestamps Qyzylorda (aka Kyzylorda) oblast in Kazakhstan moved from +06 to +05 on 2018-12-21. This is a zone split as Qostanay (aka Kostanay) did not switch, so create a zone Asia/Qostanay. Metlakatla moved from Alaska to Pacific standard time on 2018-11-04. It did not change clocks that day and remains on -08 this winter. (Thanks to Ryan Stanley.) It will revert to the usual Alaska rules next spring, so this change affects only timestamps from 2018-11-04 through 2019-03-10. Change to past timestamps Kwajalein's 1993-08-20 transition from -12 to +12 was at 24:00, not 00:00. I transcribed the time incorrectly from Shanks. (Thanks to Phake Nick.) Nauru's 1979 transition was on 02-10 at 02:00, not 05-01 at 00:00. (Thanks to Phake Nick.) Guam observed DST irregularly from 1959 through 1977. (Thanks to Phake Nick.) Hong Kong observed DST in 1941 starting 06-15 (not 04-01), then on 10-01 changed standard time to +08:30 (not +08). Its transition back to +08 after WWII was on 1945-09-15, not the previous day. Its 1904-10-30 change took effect at 01:00 +08 (not 00:00 LMT). (Thanks to Phake Nick, Steve Allen, and Joseph Myers.) Also, its 1952 fallback was on 11-02 (not 10-25). This release contains many changes to timestamps before 1946 due to Japanese possession or occupation of Pacific/Chuuk, Pacific/Guam, Pacific/Kosrae, Pacific/Kwajalein, Pacific/Majuro, Pacific/Nauru, Pacific/Palau, and Pacific/Pohnpei. (Thanks to Phake Nick.) Assume that the Spanish East Indies was like the Philippines and observed American time until the end of 1844. This affects Pacific/Chuuk, Pacific/Kosrae, Pacific/Palau, and Pacific/Pohnpei. Changes to past tm_isdst flags For the recent Morocco change, the tm_isdst flag should be 1 from 2018-10-27 00:00 to 2018-10-28 03:00. (Thanks to Michael Deckers.) Give a URL to the official decree.

America/Mexico_City incorrect DST end time for 2018.
by demxic Dec. 28, 2018

Dec. 28, 2018

I would like to draw your attention to the fact that Mexico's City Daylight time ended on October 28 2018 03:00 AM local time. That is the exact moment when clocks moved backward to 02:00 AM. Somehow your database marks DST end at 02:00 AM moving clocks backward to 01:00 AM. Please note that this is incorrect. Is it possible to correct for this? -- *My country is the world and my religion is to do good. *Thomas Paine

1932 IAU Commission on Time: abolish Summer Time
by Steve Allen Dec. 28, 2018

Dec. 28, 2018

Bulletin Horaire, vol. 4, no. 70 has a synopsis of time-related activities at the 4th General Assembly of the IAU at Cambridge Massachusetts in 1932. Page 399 has the end of the Commission 31 (Time) meeting where Kiyofuso Sotome, director of Tokyo Astronomical Observatory, proposed two items not on the printed agenda. Item 2 was "Immediate abolition of the Summer Time." The commission deemed that it could not take any action on this. http://adsbit.harvard.edu//full/1932BuBIH...4..391./0000427.000.html The same text is found in Transactions of the IAU vol. 4 page 253. -- Steve Allen <sla(a)ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB 260 Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m
