Chile time changed early?
by Matt Johnson May 13, 2016

May 13, 2016

http://www.wsj.com/articles/what-time-is-it-in-chile-theres-no-telling-1463… Since the change isn't scheduled until Sunday, the only way I can think that this happened is that the cell towers were updated prematurely. Can anyone confirm or comment? -Matt

America/ Santiago possible Correction
by Gretchen Gottsacker May 12, 2016

May 12, 2016

Greetings, I noticed there may be a discrepancy for the time zone America/ Santiago. As mentioned in the document NEWS "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." I believe is an incorrect statement as the link provided on the southamerica document provides these two links http://www.diariooficial.interior.gob.cl/versiones-anteriores/do/20160318/ and http://www.leychile.cl/Navegar?idNorma=1088502 which states that "as amended by Presidential Decree Nº106, 2015, both the Ministry of the Interior and Public Security, will be extended, as regards the year 2016, until 24 pm the second Saturday of May. Also, starting from the 24 hours of the second Saturday in August 2016 and until 24 pm the second Saturday in May 2017, the official time will advance in 60 minutes" Meaning daylight savings is not active until August 2016.

TZ Changing in Chile on May, 14th.
by Luis Martinez Villa May 3, 2016

May 3, 2016

Dear IANA TZ, Since the last time change Chile has been in GMT-3 (i.e. Chile is right now in GMT-3). Chile is going to GMT-4 in May,14th midnight and returning to GMT-3 in August, 13th midnight. That means clocks will go back 1 hour at 00:00 May 15th (jumping back to May 14th); and will go forward by 1 hour on 00:00, August 14th. In tzdata2016c I can see this new rules for Chile: # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Chile 2016 max - May Sun>=9 3:00u 0 - Rule Chile 2016 max - Aug Sun>=9 4:00u 1:00 S And I can see this Chile zone definition: # 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 But with these two information I'm not sure that in the midnight of May, 14th this tzdata2016c will change the TZ of Chile from GMT-3 to GMT-4. Can you please explain me how these structures in tzdata2016c work to accomplish the necessary TZ change in Chile. Thank you very much, best regards. Luis

Programmatic way of determining the latest release number?
by Jon Skeet April 30, 2016

April 30, 2016

Hi folks, I'm aware of the ability to use ftp://ftp.iana.org/tz/tzcode-latest.tar.gz and the similar data URL to get the latest actual files, but is there a URL which either serves an HTTP redirect to the latest version, or gives the latest version number in some other easily-retrievable machine-readable format? I could parse the content of http://www.iana.org/time-zones, but that doesn't feel like a very robust approach :) Presumably this might all drop out of the tzdist work, but I was wondering whether there was a low-tech way at the moment.

Re: [tz] Issue in Time Zone Database for Kazakhstan's zones

I'm not familiar with TZ files, but I suppose this > changes are the reason of incompatibility for some apps. > Yes, I think that's relevant to the Plasma Digital Clock bug. I found what appears to be a related bug in the way that Qt handles data from tz 2016b, so the problem is not limited to tz 2016d. I can reproduce the problem by using just the Qt base, without involving KDE or Plasma. The Qt base parses tz data directly (!), and appears to do so incorrectly. I have filed a Qt bug report here: https://bugreports.qt.io/browse/QTBUG-53071 zic.c already has workarounds for buggy programs that misparse tzdata files containing time stamps far in the past, by putting in a no-change transition before the Big Bang. Perhaps there could be a similar workaround for this Qt bug, as Qt appears to mishandle tzdata files where the predicted future uses a POSIX TZ string that assumes POSIX.1-2001 or later. That is, perhaps we can work around the Qt bug by appending to the binary data some sort of no-change transition far enough in the future that we can expect Qt to be fixed in the field before most users care about those future time stamps. The year 2116, say?

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 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
