United States Senate reintroduced Sunshine Protection Act, enabling Permanent DST
by Phake Nick Nov. 14, 2022

Nov. 14, 2022

I don't quite understand the legal text of the bill itself [2], but according to my reading, it seems like the bill will end DST across the entire US by shifting the standard time forward an hour, except in states/territories/area that currently doesn't enact DST, which they can choose to follow the new standard time or old standard time? 1: https://www.rubio.senate.gov/public/index.cfm/2021/3/rubio-colleagues-reint… 2: https://www.rubio.senate.gov/public/_cache/files/d34c77c0-acea-4074-bc57-14…

Kyiv not Kiev error

Wrong behaviour with truncated TZif files
by Almaz Mingaleev June 1, 2022

June 1, 2022

Hi Paul, I've built TZif files with following commands: mkdir /tmp/zic cd /tmp/zic git clone https://github.com/eggert/tz.git . make -C . zic make -C . NDATA= rearguard.zi mkdir data # Truncate at 1 Jan 2100. ./zic -b fat -r "/@4102444800" -d ./data rearguard.zi make TZDIR="./data" all Then I've compiled attached file: g++ mktime_test.cpp localtime.o Test tries to find epoch timestamp for 2 Jul 1980 midnight at America/Los_Angeles. With a truncated TZif file it prints 331344000. With non-truncated one it prints 331372800. The latter is the right answer. Also, date command is wrong on certain time zones: make TZDIR="./data" date TZ=Antarctica/Palmer ./date -r -631152000 prints "Sat Dec 31 20:00:00 -04 1949" even though 1 Jan 1950 offset should be zero <https://github.com/eggert/tz/blob/df4699ddfc9caf6f875f1e38703dd0ef41826175/…> .

The correct name of the capital city of Ukraine is Kyiv. Kiev is English language, as every other name in the db, not russian. It is only a coincidence that the English name is more similar to russian than to Ukrainian.

Re: [tz] Change Request: Europe/Kiev to Europe/Kyiv
by John Hawkinson March 18, 2022

March 18, 2022

I do not think we have handled this well; we have not given Victor Perov a good answer. Indeed, to some extent we've made it a "runaround." We can do better. We should take the time to write up a good lengthy explanation of the issues ("boilerplate"), because this a really important issue of concern to many people in the world and the project has indeed thought about it pretty carefully. Dismissing the inquiries because they are repetitive makes it seem like we haven't, and that unnecessarily upsets peopl. Victor Perev: I don't have time for a full write-up right now, but please consult the archives of the tz list (http://mm.icann.org/pipermail/tz/ or perhaps https://www.google.com/search?q=site%3Amm.icann.org%2Fpipermail%2Ftz%2F+kyiv which returns 203 results). The tz project is very conservative in its judgment for when the predominant English spelling of a city has changed, and so far the project has judged that Kiev is still preferred. We discussed it when major English newspapers and style guides changed from Kiev to Kyiv last year (prompted by the US presidential impeachment, which lead to a lot of discussion about Kyiv in America), and we will probably continue to discuss it as time goes on. But we've thought about it and discussed it a lot. The answers you got don't explain that, and that means we have not done a good a job as we should have. Sorry about that. In particular, I think Brian Inglis's answer was actually incorrect in a way that really matters ("Kiev is the correct English spelling"). There are multiple correct English spellings. It used to be that Kiev was the only one, but Kyiv is gaining popularity more and more. Paul Eggert <eggert(a)cs.ucla.edu> wrote on Sat, 15 Aug 2020 at 18:19:08 EDT in <cefc7f01-a3e9-f2a4-9ab9-5288147f994a(a)cs.ucla.edu>: > Thanks for bringing that to the mailing list (if I could shut off GitHub > pull requests I would). Although you cannot do so, we can handle them a little bit better. Please see https://docs.github.com/en/github/building-a-strong-community/creating-a-pu… You can create a template that explains to a would-be pull request submitter than pull requests will be closed and the project uses the mailing list for development discussions. ("I understand that the tz project does not use pull requests on github, and that if I enter a pull request here, it will be closed and I will be directed to send email to tz(a)iana.org.") For the particular case of regular, recurring issues, it may be worth while to keep one of #15, #26, and #27 open and mark the others as a duplicate of it, so that it is easier for newcomers to understand that this issue has been carefully considered and is not a simple oversight. https://github.com/eggert/tz/pulls?q=kiev Also, not to pick on Brian (again), but if the project policy is not to use github pull requests, it's not great to respond to pull requests on their substance, because it bifurcates the discussion and makes it seem like we actually do use pull requests ("except when we don't"). So what seems like a helpful thing may not be. -- jhawk(a)alum.mit.edu John Hawkinson

Jordan summer time zone is not updated in IANA database
by Abugharbieh, Raghad March 2, 2022

March 2, 2022

Hello I’m sure if you’re already aware of this or not , but in Jordan the timezone was changed on Thursday to meet summer changes. So currently , time zone in IANA database is behind the real time in Jordan by 1 hour . this is causing some time issues in websites that use IANA database. I’m sending this to check if there’s anything I can do to update the timezone for Jordan in the database to fix the root cause instead of handling the issues we have in a hacky way . Best regards , Raghad Abugharbieh

backzone Africa/Lubumbashi
by Alois Treindl Feb. 28, 2022

Feb. 28, 2022

In file backzone there is an entry for Africa/Lubumbashi # Democratic Republic of the Congo (east) Zone Africa/Lubumbashi 1:49:52 - LMT 1897 Nov 9 2:00 - CAT There are scarce sources for time zones of former Belgian Congo. My main source for its time zone history is Henri le Corre, Régimes horaires pour l'Europe et l'Afrique. He has for the eastern provinces of Zaire GMT + 1 between 1897 Nov 9 GMT + 2 since 1920 Apr 25. Shanks follows le Corre. As does Francoise Schneider Gauquelin in he book Problèmes de l'heure resolus pout le monde entier. I think this is sufficient reason to change the zone into Zone Africa/Lubumbashi 1:49:52 - LMT 1897 Nov 9 1:00 - WAT 1920 Apr 25 2:00 - CAT For the province of Kisangani, formerly Stanleyville, le Corre gives a transition from GMT +1 to GMT + 2 on 1935 Jun 14. But as this agrees with Lubumbashi after 1970, I do not expect the creation of another backzone entry for that. This task will be left for my private pre-1970 TZ extensions.

proposed change to Europe/Kaliningrad in 1945
by Alois Treindl Feb. 21, 2022

Feb. 21, 2022

Currently the zone Europe/Kaliningrad has Zone Europe/Kaliningrad 1:22:00 - LMT 1893 Apr 1:00 C-Eur CE%sT 1945 Apr 10 2:00 Poland EE%sT 1946 Apr 7 3:00 Russia MSK/MSD 1989 Mar 26 2:00s 2:00 Russia EE%sT 2011 Mar 27 2:00s 3:00 - +03 2014 Oct 26 2:00s 2:00 - EET I wonder on which source this line is based: 2:00 Poland EE%sT 1946 Apr 7 It implies these time changes: 29 April 1945 from 2:00 to 3:00 like Poland DST 1 November 1945 from 3:00 back to 2:00 Russia took control of Königsberg/Kaliningrad in East Prussia on 10 April 1045. As a general rule, Russia imposed timezone 2:00 on occupied German territory in 1945, which is the same as German DST already in force from 2 April 1945. On 24 May 1945 Russia imposed double DST, making the effective time 3:00 east, until 24 Sept 1945, when it went back to 2:00 and then back to 1:00 (CET) on 18 Nov 1945. Now what happened in Königsberg? The Potsdam agreement of 2 August 1945 : (quote from Wikipedia) > The Conference has agreed in principle to the proposal of the Soviet > Government concerning the ultimate transfer to the Soviet Union of the > City of Koenigsberg and the area adjacent to it as described above > subject to expert examination of the actual frontier. Russia annexed the area on 17 October 1945, and integrated into the republic of Russia on 7 April 1946. Poland had no role to play in this matter. Regarding time regime, I would assume that the transition from 2:00 to 1:00 of 18 Nov 1945, for occupied Germany, did not happen in Kaliningrad. It was already annexed. It remained at 2:00 until 7 April 1946, when it was integrated and went to Moscow time. This transition on 7 April 1946 is also found in Shanks. Shanks does not have the double DST from 24 May to 24 September 1945, but I think he is wrong there. Why should the Russians have treated East Prussia from the rest of the occupied German territory in May 1945. That would make the zone table like this ( I marked the difference in red) Zone Europe/Russia/Kaliningrad 1:22:00 - LMT 1893 Apr 1:00 C-Eur CE%sT 1945 Apr 10 1:00 1:00 CEST 1945 May 24 2:00 1:00 2:00 CEMT 1945 Sep 24 3:00 1:00 1:00 CEST 1945 Oct 17 2:00 - EET 1946 Apr 7 3:00 Russia MSK/MSD 1989 Mar 26 2:00s 2:00 Russia EE%sT 2011 Mar 27 2:00s 3:00 - +03 2014 Oct 26 2:00s 2:00 - EET I have tried to simplify Zone Europe/Russia/Kaliningrad 1:22:00 - LMT 1893 Apr 1:00 C-Eur CE%sT 1945 Apr 10 1:00 SovietZone CE%sT 1945 Oct 17 2:00 - EET 1946 Apr 7 3:00 Russia MSK/MSD 1989 Mar 26 2:00s 2:00 Russia EE%sT 2011 Mar 27 2:00s 3:00 - +03 2014 Oct 26 2:00s 2:00 - EET but get an error: can't determine time zone abbreviation to use just after until time at this line in tzdata.zi 1 So CE%sT 1945 O 17 This is why I made the changes implied by rule SovietZone explicit

Maryland permanent DST
by Arthur David Olson Feb. 21, 2022

Feb. 21, 2022

A permanent-DST bill has been approved by the Maryland House of Delegates on a third-and-final 108-24 vote; it now goes to the state senate. Text of the bill is available at... https://mgaleg.maryland.gov/2022RS/bills/hb/hb0126T.pdf …and status of the bill at... https://mgaleg.maryland.gov/mgawebsite/Legislation/Details/hb0126 There are contigencies: (1) enacting of a similar act by Delaware, the District of Columbia, Pennsylvania, Virginia, and West Virginia; and (2) 15 U.S.C. § 260a being amended to allow the states or a state, individually, to observe a year–round standard time that is consistent with Eastern Daylight Time Alas, if the contingencies are met there may be short lead time before a change: Section 1 of this Act shall take effect on the earlier of the second Sunday of March or the first Sunday of November after the [contigencies have been met]… Alas further, the senate (unlike the house) has returned to in-person hearings; written communications can be sent. One suggestion I’ve thought of making is to change “the earlier of” to “the later of” for kick-in; that would buy at least a few guaranteed months of lead time. I’d welcome any better suggestions; I’d also welcome any Marylander with more political weight than I have (read: anyone) to weigh in. --ado

Issues about parts of Europe/Moscow in 1981/1982
by Alois Treindl Feb. 21, 2022

Feb. 21, 2022

I have the impression that some of the comments in the Russia section in file 'europe' have not been followed through in the actual zone tables. I refer to the lines beginning here # From Stepan Golosunov (2016-03-07): # 11. Regions-violators, 1981-1982. # Wikipedia refers to # http://maps.monetonos.ru/maps/raznoe/Old_Maps/Old_Maps/Articles/022/3_1981.… # http://besp.narod.ru/nauka_1981_3.htm ... until # 12. Udmurtia Also the Russian wikipedia page https://ru.wikipedia.org/wiki/%D0%9C%D0%BE%D1%81%D0%BA%D0%BE%D0%B2%D1%81%D0… contains the sentence (in Google translation) > In the autumn of 1981, Arkhangelsk, Vologda, Yaroslavl, Ivanovo, > Vladimir, Ryazan, Lipetsk, Voronezh, Rostov-on-Don, Krasnodar and > regions to the east of those named (about 30 in total) parted ways > with Moscow time.However, the convenience of common time with Moscow > turned out to be decisive - in 1982, these regions again switched to > Moscow time. Shanks International atlas has similar information, and also the Russian book Zaitsev A., Kutalev D. A new astrologer's reference book. Coordinates of cities and time corrections, - The World of Urania, 2012 Russian: Зайцев А., Куталёв Д., Новый справочник астролога. Координаты городов и временные поправки To me it seems that an extra zone is needed, which starts with LMT util 1919, later follows Moscow since 1930, but deviates from it between 1 October 1981 until 1 April 1982. I suggest to call this zone Europe/Yaroslavl, because Yaroslavl with a population of 608'000 seems to be largest city in the deviating area.
