Thanks for reporting that. I installed the attached patch into the experimental tz version on github <https://github.com/eggert/tz>, with the intent that this fix propagate into the next tz release and thus into glibc etc.

Problem with tzselect and Dominica
by Owen Leibman May 12, 2015

May 12, 2015

Using a freshly downloaded version of tzelect, and choosing 2 (Americas) followed by 18 (Dominica), the following results: ./tzselect: line 469: /usr/share/zoneinfo/ America/Port_of_Spain: No such file or directory ./tzselect: time zone files are not set up correctly I believe that is because Dominica's abbreviation (DM) is actually found in some comments near the head of the file. To avoid this problem, I believe he awk statement at line 463: $1 ~ cc && $4 == region { print $3 } needs to be changed thus to exclude comment lines: $0 !~ /^#/ && $1 ~ cc && $4 == region { print $3 }

Re: [tz] Kyiv time zone
by sam.ua April 29, 2015

April 29, 2015

Dear Florian. perhaps you are not aware of the history between Ukraine and Russia. Let me remind you that Moscow has pursued the destruction of Ukraine, Ukrainians and the Ukrainian language and culture for many centuries. This ethnic cleansing continues today with the Russification of Ukraine. Once you destroy a nation's identity --their language, culture and history, it's quite easy to convert them into mindless robots, who are easy prey for the imperialist. Even in 1991, as we achieved our long overdue independence , Ukrane was over 80-90% pro-Russian. after two plus decades those same people, who were once slaves to the empire, have been schooled on the true history of Ukraine and understand just how devious Moscow was in it's ethnic cleansing of the Ukrainian people. Little over a year ago we got rid of the last remaining remnant of that Soviet-Russian past - the Putin puppet Yanykovych. Our cities are nearly rid of Lenin and Stalin - two monsters that murdered tens of millions of Ukrainians, but as the links you provided show, that past is still a part of the present. We are gradually getting rid of it. The issue of Kyiv vs Kiev is precisely the past vs the present. Kyiv is today, it's also what it was in the old Ruthenian-Ukrainian chronicles that date back to the 9th century. It became Kiev under Russian rule and now it's once again Kyiv. The war in Eastern Ukraine - the invasion by Russia, is a last attempt too keep Ukraine under Russia's orbit. we don't want that. My generation doesn't want that. Once again Kyiv vs Kiev is a part of that ugly past. I can promise you that all of our sites will one day be Kyiv and that the term will be the one used wide-spread and worldwide. But we need to do this one step at a time and wikipedia is a big part of this. This has to be corrected and the general population will then become familiar and accept the new word, it's very easy to spell and pronounce. I kindly ask that you respect our history, our past and what is currently happening in eastern Ukraine. it's no accident that where the Russian population - 15% of Ukraine's population. lives and breathes, there is a war. the same way Stalin killed my forefathers and replaced them with Russians from Russia, we are battling for the existence of our own unique identity. Kyiv is and will always be the proper transliterated version of our capital. there is no argument today that can supercede that. Thank you kindly, Simon Kostenko ---- On сб, 28 бер 2015 11:27:35 +0200 Florian Weimer<fw(a)deneb.enyo.de> wrote ---- * Simon: >> Many government web sites in the Ukraine still use the “Kiev” >> transliteration > For example? “While the Obama administration has publicly acknowledged it is considering supplying Kiev with arms, backed by hardline EU countries like Poland and Lithuania, German Chancellor Angela Merkel has vehemently opposed the move.” <http://www.kmu.gov.ua/control/en/publish/article?art_id=248025420>

Database and Code compatibility

Hi, I would like to know the compatibility constraints between the code and the datebase. Is the code forward and backward compatible with the database binaries? I.e can code read older and newer version of database binaries? Or do the code and the database need to be version sync with each other? Thanks Thomas Karlsson

Micronations?
by Matt Johnson April 24, 2015

April 24, 2015

I read an article today about a newly formed country:http://www.businessinsider.com/liberland-this-newly-declared-microc… Which got me thinking - What is the rule/guideline for tzdb treatment of micronations? According to it's wikipedia article (http://en.wikipedia.org/wiki/Liberland) it's currently following CET/CEST. It's on the Croatia/Serbia border, so if modeled in the TZDB it would probably be something simple like: Link Europe/Belgrade Europe/Liberpolis # Liberland Now, I'm not suggesting we add this now - but just wondering at what point we would recognize a micronation? If they were granted an ISO3166 country code, would they show up in zone.tab/zone1970.tab? If they changed their time zone or DST rules, should they get their own zone entry? What if they were never recongnized broadly, but still changed their time conventions? Do we have a policy on this? For that matter - is there a list of general policies documented anywhere?

Egypt cancels DST permanently
by Paul Eggert April 24, 2015

April 24, 2015

Yesterday the office of Egyptian President El-Sisi announced his decision to abandon DST permanently. This increases the likelihood of the correctness of our guess in 2015d for no DST in Africa/Cairo after 2015. Although the proposed patch (attached) was too late to make the cutoff for 2015d, it affects only commentary.

[tz-announce] 2015d release of tz code and data available
by Paul Eggert April 24, 2015

April 24, 2015

The 2015d 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: Changes affecting future time stamps Egypt will not observe DST in 2015 and will consider canceling it permanently. For now, assume no DST indefinitely. (Thanks to Ahmed Nazmy and Tim Parenti.) Changes affecting past time stamps America/Whitehorse switched from UTC-9 to UTC-8 on 1967-05-28, not 1966-07-01. Also, Yukon's time zone history is documented better. (Thanks to Brian Inglis and Dennis Ferguson.) Change affecting past and future time zone abbreviations The abbreviations for Hawaii-Aleutian standard and daylight times have been changed from HAST/HADT to HST/HDT, as per US Government Printing Office style. This affects only America/Adak since 1983, as America/Honolulu was already using the new style. Changes affecting code zic has some minor performance improvements.

Yukon time history updates with references containing some Canadian and global data
by Brian Inglis April 18, 2015

April 18, 2015

It seemed unlikely to me that the statement about the Yukon in line 1844 below "This is still valid;" was still valid, except in the sense that Yukon standard time may still be defined as GMT-9, although standard time in Yukon has not had that offset, and the name has not been used with that meaning, except in some historical sense, since 1973. So I tried to trace the history of Yukon time and found the following regulations, giving the reference title and URL if found, regulation name, and relevant quote if available. Each regulation specifically revokes its predecessor. The final reference is to the current Interpretation Act authorizing and resulting from these regulatory changes. Only recent regulations were retrievable via Yukon government site search or index, and only some via Canadian legal sources. Other sources used include articles titled "Standard Time and Time Zones in Canada" from JRASC via ADS Abstracts, cited by ADO for 1932 in northamerica:1456, and updated versions from 1958 and 1970 quoted below; each article includes current extracts from provincial and territorial ST and DST regulations at the end, summaries and details of standard times and daylight saving time at many locations across Canada, with time zone maps, tables and calculations for Canadian Sunrise, Sunset, and LMST; they also cover many countries and global locations, with a chart and table showing current Universal Time offsets, and may be useful as another source of information for 1970 and earlier. The coordinator should decide how much Yukon time history should change, relative to that currently documented at: northamerica:1838:# Northwest Territories, Nunavut, Yukon northamerica-1839- northamerica-1840-# From Paul Eggert (2006-03-22): northamerica-1841-# Dawson switched to PST in 1973.

Hawaii-Aleutian Standard Time
by Hank W. April 17, 2015

April 17, 2015

I happened to notice that the U.S. Code of Federal Regulations, Title 49, Subtitle A, Part 71, Section 71.12 states "...the Hawaii-Aleutian standard time zone, includes the entire State of Hawaii and, in the State of Alaska, that part of the Aleutian Islands that is west of 169 degrees 30 minutes west longitude." The America/Adak Zone data include this change, but the Pacific/Honolulu Zone data do not. Hank Wisniewski, Austin, Texas, U.S.A.

Samoa Standard Time
by Hank W. April 16, 2015

April 16, 2015

FYI: I sent the following message to my U.S. Senators and my U.S. Representative: Whereas there exists a country which has been named Samoa since July 1997, Whereas Samoa is entirely separate from the Territory of American Samoa, Whereas Samoa and American Samoa have had standard times since 1911, Whereas the standard time in Samoa has differed from the standard time in American Samoa since the 30th of December 2011 (in addition to the period from 1911 to 1950, when the time in Western Samoa was known as Samoa Time and the time in American Samoa was known as Nome Standard Time), and Whereas the standard times in both locations continue to be known as Samoa Standard Time, Despite the report in the Samoa Wikipedia article that American Samoans protested Samoa's name change and continue to call it Western Samoa, and Despite the difference between the abbreviations of Samoa's Samoa Standard Time (WSST) and American Samoa's Samoa Standard Time (SST), which is due to the fact that the ISO-3166 international standard abbreviation of Samoa is still WS, In the interest of reducing international confusion, I recommend that the Code of Federal Regulations, Title 49, Subtitle A, Part 71, Section 71.13 and the United States Code, Title 15, Chapter 6, Subchapter IX, Section 263 be amended to change the name of the standard time in American Samoa from Samoa standard time to American Samoa standard time. Although I hope they make the change, I'm not holding my breath. I sent a similar message last year to the U.S. Department of Transportation, the Executive Department in charge of U.S. time zones, but received no reply. Besides, if we were interested in reducing international confusion, we would have switched to the metric system. Hank Wisniewski, Austin, Texas, U.S.A.

Belarus is listed in MSK timezone
by Dzmitry Kazimirchyk April 14, 2015

April 14, 2015

I am in Belarus and I have recently noticed that my local timezone is displayed as MSK (Moscow Time) instead of FET (Further Eastearn European Time). Belarus has not made any changes to its timezone (daylight saving) policies recently, so I guess the reasoning behind this is that Russia have changed its time effectively putting its internal MSK timezone into the same time Belarus already had. However this doesn't cancel out the fact that Belarus is an independent country and it is very strange for a country to be listed under an internal timezone of some other country... Could anyone please shed some light on the reasoning behind putting Belarus into MSK timezone and if we can get our FET timezone back or at least have MSK changed to something neutral. Best regards, Dzmitry Kazimirchyk

timeanddate.com reported that Luhansk and Donetsk, the two easternmost Ukrainian regions, did not switch back to EET with the rest of Ukraine on 26 Oct 2014 but are now "permanently" on MSK. However, the 2015b europe data file does not seem to reflect that. Hank Wisniewski, Austin, Texas, U.S.A.

[tz-announce] 2015c release of tz code and data available
by Paul Eggert April 14, 2015

April 14, 2015

The 2015c 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. Although this release is based on the best information we had when it was made, the daylight-saving situation in Egypt seems to be fluid, and we may need to generate another release soon. Changes affecting future time stamps Egypt's spring-forward transition is at 24:00 on April's last Thursday, not 00:00 on April's last Friday. 2015's transition will therefore be on Thursday, April 30 at 24:00, not Friday, April 24 at 00:00. Similar fixes apply to 2026, 2037, 2043, etc. (Thanks to Steffen Thorsen.) Changes affecting past time stamps The following changes affect some pre-1991 Chile-related time stamps in America/Santiago, Antarctica/Palmer, and Pacific/Easter. The 1910 transition was January 10, not January 1. The 1918 transition was September 10, not September 1. The UTC-4 time observed from 1932 to 1942 is now considered to be standard time, not year-round DST. Santiago observed DST (UTC-3) from 1946-07-15 through 1946-08-31, then reverted to standard time, then switched its time zone to UTC-5 on 1947-04-01. Assume transitions before 1968 were at 00:00, since we have no data saying otherwise. The spring 1988 transition was 1988-10-09, not 1988-10-02. The fall 1990 transition was 1990-03-11, not 1990-03-18. Assume no UTC offset change for Pacific/Easter on 1890-01-01, and omit all transitions on Pacific/Easter from 1942 through 1946 since we have no data suggesting that they existed. One more zone has been turned into a link, as it differed from an existing zone only for older time stamps. As usual, this change affects UTC offsets in pre-1970 time stamps only. The zone's old contents have been moved to the 'backzone' file. The affected zone is America/Montreal. Changes affecting commentary Mention the TZUpdater tool. Mention "The Time Now".
