Issue in Time Zone Database for Kazakhstan's zones
by Zhanibek Adilbekov April 28, 2016

April 28, 2016

After upgrading tzdata to 2016d version some of applications unable to determine right timezone for all zones which belong to Kazakhstan. I personally use Asia/Almaty (which is +06:00 and no DST) on my machine (Arch Linux with Plasma 5.6), and it leads some programs to produce unexpected results. E.g.: Digital Clock applet shows -12 hours from current time and Plasma Lockscreen shows time in UTC. I tried downgrade to 2016c and it works just fine. Please fix the issue, or at least return to previous state (which worked fine). Thanks! -- Best regards, Zhanibek Adilbekov.

Montreal timezone
by Vincent Tourneyrie April 23, 2016

April 23, 2016

Dear Sir, Madam, I discovered that you are at the origin of the removal of the Montreal/America timezone and it's integration within Toronto. The problem is that this move to a secondary timezone leads to tons of problems and hours of corrections and explanation (mainly due to quick and dirty implementations of TZ but I cannot blame half of the developers of the planet). The fact that PHP uses this list expose this timezone list to the public. I got many angry comments on this change from French speaking people and Europeans because Toronto is less recognized and known (not to mention loved) than Montreal. We have 8 millions of Quebec people which will drag their feet to adopt (in fact most of them put NY) and probably half of 220 millions francophone who have no idea where Toronto is (like many people know where Geneva is but have no idea where Zurich is). It looks that you do not get that end users use this. I understand the willing of normalization but Toronto will never be significant as TZ name for all Eastern Time in Canada. I think this change has to be reversed, -- Vincent Tourneyrie Vinceti 514 907 9124 Visitez www.vinceti.ca[1] -------- [1] http://www.vinceti.ca

[tz-announce] 2016d release of tz code and data available
by Paul Eggert April 18, 2016

April 18, 2016

The 2016d 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 America/Caracas switches from -0430 to -04 on 2016-05-01 at 02:30. (Thanks to Alexander Krivenyshev for the heads-up.) Asia/Magadan switches from +10 to +11 on 2016-04-24 at 02:00. (Thanks to Alexander Krivenyshev and Matt Johnson.) New zone Asia/Tomsk, split off from Asia/Novosibirsk. It covers Tomsk Oblast, Russia, which switches from +06 to +07 on 2016-05-29 at 02:00. (Thanks to Stepan Golosunov.) Changes affecting past time stamps New zone Europe/Kirov, split off from Europe/Volgograd. It covers Kirov Oblast, Russia, which switched from +04/+05 to +03/+04 on 1989-03-26 at 02:00, roughly a year after Europe/Volgograd made the same change. (Thanks to Stepan Golosunov.) Russia and nearby locations had daylight-saving transitions on 1992-03-29 at 02:00 and 1992-09-27 at 03:00, instead of on 1992-03-28 at 23:00 and 1992-09-26 at 23:00. (Thanks to Stepan Golosunov.) Many corrections to historical time in Kazakhstan from 1991 through 2005. (Thanks to Stepan Golosunov.) Replace Kazakhstan's invented time zone abbreviations with numeric abbreviations.

Magadan (Russia) may change it time zone on April 24, 2016
by Alexander Krivenyshev April 14, 2016

April 14, 2016

Just to reconfirm that 6 Russian regions: Astrakhan Oblast (Astrakhan), Ulyanovsk Oblast (Ulyanovsk), Altai Krai (Barnaul), Altai republic (Gorno- Altaysk), Zabaykalsky Krai (Chita), Sakhalin Oblast (Yuzhno-Sakhalinsk) changed their time zones on March 27, 2016. See new time zones map of Russia: http://www.worldtimezone.com/time-russia12.php or http://www.worldtimezone.com/time-russia24.php Seems that 7th region (Magadan Oblast / Magadan) which have submitted draft bill 948300-6 to change its time zone from UTC+10 to UTC+11 as of March 23, 2016 passed its 3rd reading by the State Duma and if approved by the Federation Council, will take into effect as the Federal Law on April 24, 2016 at at 2 o'clock 00 minutes.

Russian Legislation Status
by Matt Johnson April 13, 2016

April 13, 2016

I'm watching the Russian bills very closely. Current status: Transbaikal and Astrakhan have both been signed into law by the president and published. Sakhalin, Ulyanovsk, Altai Republic, and Altai Krai have all been approved by both legislative bodies, and are awaiting signature by the president. Magadan has no approvals yet. It is on the agenda for discussion for March 15th, per the meeting notices published at http://asozd2.duma.gov.ru It seems unlikely to me that it will pass with a March 27th effective date as currently written, but that's just my opinion. Another two bills were found for the Tomsk region. One has a date of March 8th, the other has a date of May 29th. I'm not quite sure of the difference between the two, but neither have approvals yet or are on the agenda.

Sri Lanka Standard Time
by Matt Johnson April 12, 2016

April 12, 2016

Sri Lanka and India are both on UTC+05:30, but it would appear that Sri Lankans may be using the term "Sri Lanka Standard Time", abbreviated SLST. The Asia/Colombo zone currently shows IST for the abbreviation. Some research I uncovered: https://en.wikipedia.org/wiki/Sri_Lanka_Standard_Time http://www.priu.gov.lk/news_update/Current_Affairs/ca201104/20110412standar… http://www.infolanka.com/news/IL/1474.htm It appears that on April 11th, 2011, the President of Sri Lanka declared SLST as the official time of Sri Lanka. The official site at http://sltime.org appears to be down at the moment, but archive.org shows it clearly using SLST when it was up.

Re: [tz] Regarding new Time Zone and DST for Chile 2016 - Possible corrections on tzdata2016c.tar.gz
by Carlos Huenchullan April 8, 2016

April 8, 2016

Hello all, Regarding the last Time Zone Data, two possible corrections could be applied for Chile rules (southamerica file) 1. Rules are pointed to Zone America/Santiago and Pacific/Easter. But it missing the links to Chile/Continental and Chile/EasterIsland. We tested in a Solaris 10 server with TZ=Chile/Continental and the new rules were not applied. So the following two lines should be applied at the end of Chile section: Link America/Santiago Chile/Continental Link Pacific/Easter Chile/EasterIsland 2. The following suggestion is about how it is defined the Time Zone for Chile and if it applies DST or not. This change is to keep an accurate time zone defined, CLT or CLST, this year. Before May 15th the Time Zone is CLT (UTC -3). If we applied the new rules now, the time zone will be CLST (UTC -3) until May 15th. The time will be fine, but the timezone is not ok. My suggestion is to add the following lines marked in green in the Zone section: # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Santiago -4:42:46 - LMT 1890 -4:42:46 - SMT 1910 Jan 10 # Santiago Mean Time -5:00 - CLT 1916 Jul 1 # Chile Time -4:42:46 - SMT 1918 Sep 10 -4:00 - CLT 1919 Jul 1 -4:42:46 - SMT 1927 Sep 1 -5:00 Chile CL%sT 1932 Sep 1 -4:00 - CLT 1942 Jun 1 -5:00 - CLT 1942 Aug 1 -4:00 - CLT 1946 Jul 15 -4:00 1:00 CLST 1946 Sep 1 # central Chile -4:00 - CLT 1947 Apr 1 -5:00 - CLT 1947 May 21 23:00 -4:00 Chile CL%sT 2015 Apr 26 3:00u -3:00 - CLT 2016 May 15 3:00u -4:00 Chile CL%sT Zone Pacific/Easter -7:17:28 - LMT 1890 -7:17:28 - EMT 1932 Sep # Easter Mean Time -7:00 Chile EAS%sT 1982 Mar 14 3:00u # Easter Time -6:00 Chile EAS%sT 2015 Apr 26 3:00u -5:00 - EAST 2016 May 15 3:00u -6:00 Chile EAS%sT Regards, Carlos Huenchullán

2016c on illumos - problems with new Russia entries
by Dan McDonald April 8, 2016

April 8, 2016

I was about to bump TZ on illumos (the open-source inheritor of what was OpenSolaris) but I encountered these when building: "europe", line 2551: warning: time zone abbreviation differs from POSIX standard (+03) "europe", line 2552: warning: time zone abbreviation differs from POSIX standard (+05) (rule from "europe", line 599) "europe", line 2552: warning: time zone abbreviation differs from POSIX standard (+04) (rule from "europe", line 600) "europe", line 2627: warning: time zone abbreviation differs from POSIX standard (+03) "europe", line 2628: warning: time zone abbreviation differs from POSIX standard (+05) (rule from "europe", line 599) "europe", line 2628: warning: time zone abbreviation differs from POSIX standard (+04) (rule from "europe", line 600) "europe", line 2630: warning: time zone abbreviation differs from POSIX standard (+02) (rule from "europe", line 603) "europe", line 2711: warning: time zone abbreviation differs from POSIX standard (+06) "europe", line 2712: warning: time zone abbreviation differs from POSIX standard (+08) (rule from "europe", line 599) "europe", line 2712: warning: time zone abbreviation differs from POSIX standard (+07) (rule from "europe", line 600) Now it is possible that the zic(1) utility for illumos needs some updating. OTOH, I've never had a problem until this specific update. The entries in question are (with markings): Zone Europe/Astrakhan 3:12:12 - LMT 1924 May **HERE*** 3:00 - +03 1930 Jun 21 **HERE*** 4:00 Russia +04/+05 1989 Mar 26 2:00s 3:00 Russia +03/+04 1991 Mar 31 2:00s 4:00 - +04 1992 Mar 29 2:00s 3:00 Russia +03/+04 2011 Mar 27 2:00s 4:00 - +04 2014 Oct 26 2:00s 3:00 - +03 2016 Mar 27 2:00s 4:00 - +04 Zone Europe/Ulyanovsk 3:13:36 - LMT 1919 Jul 1 2:00 **HERE*** 3:00 - +03 1930 Jun 21 **HERE*** 4:00 Russia +04/+05 1989 Mar 26 2:00s 3:00 Russia +03/+04 1991 Mar 31 2:00s **HERE*** 2:00 Russia +02/+03 1992 Jan 19 2:00s 3:00 Russia +03/+04 2011 Mar 27 2:00s 4:00 - +04 2014 Oct 26 2:00s 3:00 - +03 2016 Mar 27 2:00s 4:00 - +04 Zone Asia/Barnaul 5:35:00 - LMT 1919 Dec 10 **HERE*** 6:00 - +06 1930 Jun 21 **HERE*** 7:00 Russia +07/+08 1991 Mar 31 2:00s 6:00 Russia +06/+07 1992 Jan 19 2:00s 7:00 Russia +07/+08 1995 May 28 6:00 Russia +06/+07 2011 Mar 27 2:00s 7:00 - +07 2014 Oct 26 2:00s 6:00 - +06 2016 Mar 27 2:00s 7:00 - +07 I checked the mailing list archives quickly, but didn't see anything about Astrakhan, so I figured nobody else has seen this yet. I'm no expert in these... I just happen to update the illumos ones for the community every time my distro (OmniOS) gets ready to ship an update. Thanks, Dan McDonald -- OmniOS Engineering

by Bogdan Denkovych April 1, 2016

April 1, 2016

I see mistake in Time Zone name 'Europe/Kiev'. Must be 'Europe/Kyiv'. Word 'Kiev' translated from Russian language, this is not correct for Ukrainian. 'Kyiv' is correct! It is translated from Ukrainian language. it limits/mocks for the Ukrainian language and people. Could you please change it? thanks! - Bogdan bogdanvlviv(a)gmail.com

Kazakhstan, 1991-2005; Russia and RussiaAsia, 1992
by Stepan Golosunov March 27, 2016

March 27, 2016

Hi! While searching for the text of the 1988 act "about a change in calculation of time on the territories of Volgograd and Saratov oblasts" I ran into a similarly titled document from 1992 Kazakhstan. Review of the linked documents from http://adilet.zan.kz/ produced the following data for post-1991 Kazakhstan: 0. Act of the Cabinet of Ministers of the USSR from 04.02.1991 N 20 http://pravo.gov.ru/proxy/ips/?docbody=&nd=102010545 removed the extra hour ("decree time") on the territory of the USSR starting with the last Sunday of March 1991. It also allowed (but not mandated) Kazakh SSR, Kirghiz SSR, Tajik SSR, Turkmen SSR and Uzbek SSR to not have "summer" time. The 13.01.1992 act also refers to the act of the Cabinet of Ministers of the Kazakh SSR from 20.03.1991 N 170 "About the act of the Cabinet of Ministers of the USSR from 04.02.1991 N 20" but I didn't found its text. According to Izvestia newspaper № 68 (23334) from 1991-03-20 (page 6; available at http://libinfo.org/newsr/newsr2574.djvu via http://libinfo.org/index.php?id=58564) on 1991-03-31 at 2:00 during transition to "summer" time: Republic of Georgia, Latvian SSR, Lithuanian SSR, SSR Moldova, Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug were to move clocks 1 hour forward. Kazakh SSR (excluding Uralsk oblast); Republic of Kyrgyzstan, Tajik SSR; Andijan, Jizzakh, Namangan, Sirdarya, Tashkent, Fergana oblasts of the Uzbek SSR were to move clocks 1 hour backwards. Other territories were to not move clocks. When the "summer" time would end on 1991-09-29, clocks were to be moved 1 hour backwards on the territory of the USSR excluding Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan. Apparently there were last minute changes. Apparently Kazakh act N 170 was one of such changes. https://ru.wikipedia.org/wiki/%D0%94%D0%B5%D0%BA%D1%80%D0%B5%D1%82%D0%BD%D0… claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast) were to not move clocks and Uralsk oblast was to move clocks forward; on 1991-09-29 Kazakhstan was to move clocks backwards. (Probably there were changes even after that publication. There is an article claiming that Kaliningrad oblast decided on 1991-03-29 to not move clocks.) This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06 to +04/+05. It's unclear how Kzyl-Orda oblast moved into the fifth time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?) Currently tzdata says that all Kazakh zones remained on +04, +05 or +06 during the whole 1991 year. This is inconsistent (except for Asia/Qyzylorda) with the 1992 documents. 1. Act of the Cabinet of Ministers of the Republic of Kazakhstan from 13.01.1992 N 28 http://adilet.zan.kz/rus/docs/P920000028_ (text includes modification from the 1996 act) introduced new rules for calculation of time, mirroring Russian 08.01.1992 act. It specified that time would be calculated according to time belts plus extra hour ("decree time"), moved clocks on the whole territory of Kazakhstan 1 hour forward on 1992-01-19 at 2:00, specified DST rules. It acknowledged that Kazakhstan was located in the fourth and the fifth time belts and specified the border between them to be located east of Kustanay and Aktyubinsk oblasts (notably including Turgai and Kzyl-Orda oblasts into the fifth time belt). This means switch on 1992-01-19 at 2:00 from +04/+05 to +05/+06 for Asia/Aqtau, Asia/Aqtobe, Asia/Oral, Atyrau and Kustanay oblasts; from +05/+06 to +06/+07 for Asia/Almaty and Asia/Qyzylorda (and Arkalyk). Currently tzdata contains only Asia/Qyzylorda change. 2. Act of the Cabinet of Ministers of the Republic of Kazakhstan from 27.03.1992 N 284 http://adilet.zan.kz/rus/docs/P920000284_ cancels extra hour ("decree time") for Uralsk and Kzyl-Orda oblasts since the last Sunday of March 1992, while keeping them in the fourth and the fifth time belts respectively. This means change from +05/+06 to +04/+05 for Asia/Oral and from +06/+07 to +05/+06 for Asia/Qyzylorda on 1992-03-29. 3. Order of the Prime Minister of the Republic of Kazakhstan from 23.09.1994 N 384 http://adilet.zan.kz/rus/docs/R940000384_ cancels the extra hour ("decree time") on the territory of Mangystau oblast since the last Sunday of September 1994 (saying that time on the territory would correspond to the third time belt as a result). This means change from +05/+06 to +04/+05 for Asia/Aqtau. Current tzdata guesses the change was done in 1995: # Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time # IATA SSIM mentions a third time zone in Kazakhstan. 5:00 RussiaAsia AQT%sT 1995 Mar lastSun 2:00 # Aqtau Time 4:00 RussiaAsia AQT%sT 2005 Mar 15 4. Act of the Government of the Republic of Kazakhstan from 08.05.1996 N 575 http://adilet.zan.kz/rus/docs/P960000575_ amends the 13.01.1992 act to end summer time in October instead of September, mirroring identical Russian change from 23.04.1996 act. 5. Act of the Government of the Republic of Kazakhstan from 26.03.1999 N 305 http://adilet.zan.kz/rus/docs/P990000305_ cancels the extra hour ("decree time") for Atyrau oblast since the last Sunday of March 1999 while retaining the oblast in the fourth time belt. This means change from +05/+06 to +04/+05. There is no zone for Atyrau currently (listed under Asia/Aqtau in zone1970.tab). 6. Act of the Government of the Republic of Kazakhstan from 23.11.2000 N 1749 http://adilet.zan.kz/rus/archive/docs/P000001749_/23.11.2000 replaces the previous five documents. The only changes I noticed are in definition of the border between the fourth and the fifth time belts. They account for changes in spelling and administrative division (splitting of Turgai oblast in 1997 probably changed time in territories incorporated into Kostanay oblast (including Arkalyk) from +06/+07 to +05/+06) and move Kyzylorda oblast from being in the fifth time belt and not using decree time into the fourth time belt (no change in practice). 7. Act of the Government of the Republic of Kazakhstan from 29.12.2003 N 1342 http://adilet.zan.kz/rus/docs/P030001342_ modified the 23.11.2000 act. No relevant changes, apparently. 8. Act of the Government of the Republic of Kazakhstan from 20.07.2004 N 775 http://adilet.zan.kz/rus/archive/docs/P040000775_/20.07.2004 modified the 23.11.2000 act to move Kostanay and Kyzylorda oblasts into the fifth time belt and add Aktobe oblast to the list of regions not using extra hour ("decree time"), leaving Kazakhstan with only 2 time zones (+04/+05 and +06/+07). The changes were to be implemented during DST transitions in 2004 and 2005 but the acts got radically amended before implementation happened. 9. Act of the Government of the Republic of Kazakhstan from 15.09.2004 N 1059 http://adilet.zan.kz/rus/docs/P040001059_ modified the 23.11.2000 act to remove exceptions from the "decree time" (leaving Kazakhstan in +05/+06 and +06/+07 zones), amended the 20.07.2004 act to implement changes for Atyrau, West Kazakhstan, Kostanay, Kyzylorda and Mangystau oblasts by not moving clocks during the 2014 transition to "winter" time. This means transition from +04/+05 to +05/+06 for Atyrau oblast (no zone currently), Asia/Oral, Asia/Aqtau and transition from +05/+06 to +06/+07 for Kostanay oblast (Kostanay and Arkalyk, no zones currently) and Asia/Qyzylorda on 2004-10-31 at 3:00. Currently tzdata has some of these transitions on 2015-03-15. 10. Act of the Government of the Republic of Kazakhstan from 15.03.2005 N 231 http://adilet.zan.kz/rus/docs/P050000231_ removes DST provisions from the 23.11.2000 act, removes most of the (already implemented) provisions from the 20.07.2004 and 15.09.2004 acts, comes into effect 10 days after official publication. The only practical effect seems to be the abolition of the summer time. Current tzdata says the change was on 2005-03-15 but the act was not supposed to come into effect until at least 10 days later. It would be simpler to use the 2004-10-31 date. Unamended version of the act of the Government of the Russian Federation N 23 from 08.01.1992 http://pravo.gov.ru/proxy/ips/?docbody=&nd=102014034&rdk=0 says that every year clocks were to be moved forward on last Sunday of March at 2 hours and moved backwards on last Sunday of September at 3 hours. It was amended in 1996 to replace September with October. Kazakh 13.01.1992 act appears to provide the same rules and 27.03.1992 act was to be enacted on the last Sunday of March 1992. Is there any reason why tzdata contains exception for 1992? Rule Russia 1992 only - Mar lastSat 23:00 1:00 S Rule Russia 1992 only - Sep lastSat 23:00 0 - Rule RussiaAsia 1992 only - Mar lastSat 23:00 1:00 S Rule RussiaAsia 1992 only - Sep lastSat 23:00 0 - (Hmm. Was the source for the 1992 transitions providing data for Moscow in UTC?)

Due to the Government`s decision daylight saving time adjustment will not be in Azerbaijan - Java
by Anar Qocayev March 24, 2016

March 24, 2016

Dear IANA Due to the Government`s decision daylight saving time adjustment will not be in Azerbaijan. So we need Java(JDK) system in Yapi Kredi Azerbaijan not to adjust the time automatically. Could you please work on it ?. If it takes to pass to the private patch and our support during process we are ready to work parallel. Because of limited time we need your urgent help. It looks like this decision was just made last week, March 17th which is two days after the latest tzdata file has been released by the TimeZone Standards body ICANN/IANA. http://www.azernews.az/azerbaijan/94137.html http://en.trend.az/azerbaijan/society/2508394.html http://www.contact.az/docs/2016/Social/031700150154en.htm#.VvGf_kZQ0Xg Investigating this decision about Azerbaijan DST decision.

[tz-announce] 2016c release of tz code and data available
by Paul Eggert March 23, 2016

March 23, 2016

The 2016c release of the tz code and data is available. Its most urgent change is for Asia/Baku, where the update takes effect this weekend. This release 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 Azerbaijan no longer observes DST. (Thanks to Steffen Thorsen.) Chile reverts from permanent to seasonal DST. (Thanks to Juan Correa for the heads-up, and to Tim Parenti for corrections.) Guess that future transitions are August's and May's second Saturdays at 24:00 mainland time. Also, call the period from 2014-09-07 through 2016-05-14 daylight saving time instead of standard time, as that seems more appropriate now. Changes affecting past time stamps Europe/Kaliningrad and Europe/Vilnius changed from +03/+04 to +02/+03 on 1989-03-26, not 1991-03-31. Europe/Volgograd changed from +04/+05 to +03/+04 on 1988-03-27, not 1989-03-26. (Thanks to Stepan Golosunov.) Changes to commentary Several updates and URLs for historical and proposed Russian changes. (Thanks to Stepan Golosunov, Matt Johnson, and Alexander Krivenyshev.) Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2016c.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2016c.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2016c.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2016c.tar.gz As usual, links to the latest release files are here: http://www.iana.org/time-zones/repository/tzcode-latest.tar.gz http://www.iana.org/time-zones/repository/tzdata-latest.tar.gz ftp://ftp.iana.org/tz/tzcode-latest.tar.gz ftp://ftp.iana.org/tz/tzdata-latest.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs.

DST reestablished in Chile
by Mauricio Ubilla March 23, 2016

March 23, 2016

Dear Paul Eggert, IANA community. The chilean government recently reestablished DST for Chile, for a period of 3 months, "from the second saturday of May to the second saturday of August. This change is starting this year, in May 14th. Here's the official link to the decree law 253 published on March 16th, stating this change: http://www.leychile.cl/Navegar?idNorma=1088502 I would like to know if this has been previously informed (I just joined the mailing list) and if is scheduled to be fixed in the next update to the TZ Database. Thanks in advance. -- Mauricio Ubilla Carvajal
