Java TZDB compiler
by Marcos Passos Jan. 26, 2019

Jan. 26, 2019

Hello, The Java TZDB compiler models transitions in terms of historical transitions and transition rules. All transition rules start one year after the latest year among the unbounded rules in the TZDB database for a given zone. Reading the docs, I found the following explanation about that extra year: Also add one more year to avoid weird case where penultimate year has odd > offset. Does anyone know what does it mean and in which cases does it occur? - Marcos

How long will the rearguard formats continue be provided?
by Pramoth Murali Jan. 25, 2019

Jan. 25, 2019

Hello! Our team utilizes a custom version of tzcode and a calendar utility that don't support negative DST offsets that was brought back in 2018e nor the 2018f fallback transactions Japan rules that were at 25:00 hour. We utilized 2018i rearguard-format version and we were able to utilize 2018i with our parsers. The 2018i announcement mentions that the rearguard is intended to be a temporary transition aid; that raises fear if we have to patch one of the upcoming tzdata releases that don't provide a rearguard with similar fixes. While we are planning to work on fixes for our timezone parsers; in order to ensure we have enough leeway for our new solutions, we would be curious to know how long will these rearguard versions (with no negative offsets) continue to be provided?

Hello. The Metlakatla community in Alaska has decided not to change its clock back an hour starting on November 4th, 2018 (day before yesterday). They will be gmtoff=-28800 year-round. I'm told this is the list to send this information to. Any assistance or advice on getting this updated in the database is appreciated. https://www.facebook.com/141055983004923/photos/pb.141055983004923.-2207520… [image: MIC time change.jpg] - Ryan _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ AKTechOps <http://serrc.org/techops> | techops(a)serrc.org | *(907) 523-7290* *| Brian 523-7248 | Michaela 523-7258 | Nate 523-7275 | Nick 523-7291 | Ryan 523-7272 | SERRC 586-6806 |*

There is a checksum in the file, but it only covers the non-comment digits in the file. (so white space changes are OK) The payload lines must start on column 1 - no leading white space. -- These are my opinions. I hate spam.

Conrad Maldives Rangali Island resort
by Deborah Goldsmith Jan. 20, 2019

Jan. 20, 2019

Apparently, this resort in the Maldives has its own time zone and observes GMT+06 year round, unlike Male at GMT+05. It looks like we’d need a new zone for this. Source: Internal reports and: http://conradglobalmediacenter.com/assets/CNRD/docs/FactSheets/ConradMaldiv… (search for “Local Time”) I wasn’t able to find any source contradicting this information. Apparently it’s a known issue that Maldives resort islands have their own (unofficial) time zones: https://www.timeanddate.com/time/zone/maldives At the moment, users need to find a time zone that has the same GMT offset (in this case Indian/Chagos works) and use that instead. Thanks, Debbie

Some rules in tz specification files seem to be applied (by zic) outside of their declared period of applicability
by Parsifal Herzog Jan. 19, 2019

Jan. 19, 2019

In the example shown below, copied from from tzdata2018i Africa file, the last Zone line, referencing the Namibia rule, should start at 1990 March 21 2:00 am. There are no Namibia transitions defined from that start, until 1994. However zic does create a transition using the second Namibia rule at the start time, as shown in the zdump output below. There are many other cases like this, where an UNTIL specification ends well before the next applicable rule of the following zone line. I am trying to read the zic manual page as a specification, and I do not understand why zic inserts that transition. It seems to me that either the last Zone line (SAST) would remain in effect until 1994, as there is no other transition defined, or that period is in an undefined state, as the SAST transition is not in effect after1990 March 21. Can someone correct my understanding? ------- Specification extract # RULE NAME FROM TO TYPE IN ON AT SAVE LETTER/S # Vanguard section, for zic and other parsers that support negative DST.

Brasil DST changes
by Dedeco Balaco Jan. 15, 2019

Jan. 15, 2019

Hello, last year, the DST automatic adjust for my recently installed system was wrong. It is a Debian 9 install. I adjusted it manually in the start and end or the period. It was not done according to what was defined by our State sometime before. Please note that it was not something done close to the change date. My friends and I looked around a bit, and we found that this change should have passed here somehow. Next year, I do not know how it will be. Who is responsible for this kind of information or update?

Notice Lead Time Tracking
by Brian Inglis Jan. 13, 2019

Jan. 13, 2019

Given some recent last minute end of year announcements, could I please suggest creating a new document to formally track metadata about every time change notice's lead time from 2019, as a basis for stats, info, distributor/vendor additions and enhancements, walls of shame, etc. as this has never yet been suggested AFAIR. I could see vendors like Apple, Google, Microsoft, Oracle dev groups adding columns to local copies to track their own responses, and using those to prod government officials to do better. The document could be a text file containing an HTML document with a table tracking: CC, announcement date[/time], effective date[/time], lead time in years-months-days [hours:minutes:seconds], tzdb release date[/time], tzdb release lead time +/- in years-months-days [hours:minutes:seconds], whether change affects STD, whether change affects DST, number of zones impacted, list of zones impacted, comments about missing details etc.; with dates[/times] in ISO formats (and perhaps also Unix format metadata attributes, allowing for JS HTML text display customization and sorting by third party users); times only specified when useful or notice is days, and times are available and accurate. If anyone has been doing this already, perhaps they could contribute their data; and anyone with interest and time could backfill data from mailing list posts. -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada This email may be disturbing to some readers as it contains too much technical detail. Reader discretion is advised.

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
