Troll and zic warnings
by Arthur David Olson March 25, 2014

March 25, 2014

It may be useful to have zic warn when producing a binary with more than 1200 transition times; one possibility is attached (and appears below with tabs mangled). To make room for the new code, a warning about pre-1998 versions of zic has been removed.-) @dashdashado *** tz2014braw/zic.c 2014-03-20 23:21:43.000000000 -0400 --- tz2014bcooked/zic.c 2014-03-25 10:19:28.470390300 -0400 *************** *** 962,969 **** error(_("time overflow")); return 0; } - if (noise && hh == HOURSPERDAY && mm == 0 && ss == 0) - warning(_("24:00 not handled by pre-1998 versions of zic")); if (noise && (hh > HOURSPERDAY || (hh == HOURSPERDAY && (mm != 0 || ss != 0)))) warning(_("values over 24 hours not handled by pre-2007 versions of zic")); --- 962,967 ---- *************** *** 1503,1508 **** --- 1501,1508 ---- } timecnt = toi; } + if (noise && timecnt > 1200) + warning(_("pre-2014 clients may mishandle more than 1200 transition times")); /* ** Transfer. */

[tz-announce] 2014b release of tz code and data available
by Paul Eggert March 25, 2014

March 25, 2014

The 2014b 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 near-future time stamps Crimea switches to Moscow time on 2014-03-30 at 02:00 local time. (Thanks to Alexander Krivenyshev.) Move its zone.tab entry from UA to RU. New entry for Troll station, Antarctica. (Thanks to Paul-Inge Flakstad and Bengt-Inge Larsson.) This is currently an approximation; a better version will require the zic and localtime fixes mentioned below, and the plan is to wait for a while until at least the zic fixes propagate. Changes affecting code 'zic' and 'localtime' no longer reject locations needing four transitions per year for the forseeable future. (Thanks to Andrew Main (Zefram).) Also, 'zic' avoids some unlikely failures due to integer overflow. Changes affecting build procedure 'make check' now detects Rule lines defined but never used. The NZAQ rules, an instance of this problem, have been removed. Changes affecting commentary and documentation Fix Tuesday/Thursday typo in description of time in Israel. (Thanks to Bert Katz via Pavel Kharitonov and Mike Frysinger.) Microsoft Windows 8.1 doesn't support tz database names. (Thanks to Donald MacQueen.) Instead, the Microsoft Windows Store app library supports them. Add comments about Johnston Island time in the 1960s. (Thanks to Lyle McElhaney.) Morocco's 2014 DST start will be as predicted. (Thanks to Sebastien Willemijns.) Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2014b.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2014b.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2014b.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2014b.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs.

Macao vs Macau in tzdata2014a/iso3166.tab
by Tomas Klacko March 23, 2014

March 23, 2014

Hi, the tzdata2014a/iso3166.tab lists "MO Macau". It used to be "MO Macao", for instance in tzdata2013d. Looking at: http://www.iso.org/iso/home/standards/country_codes/updates_on_iso_3166.htm it shows "MO Macao" (via the OBP link on page 14). I would like to check, is the "MO Macau" entry in tzdata2014a/iso3166.tab correct? Thank you, Tomas

Time zone in Troll station
by Bengt-Inge Larsson March 21, 2014

March 21, 2014

Hello IANA! I have noticed that a number of research stations in Antarctica are listed in the tz database, but none in the UTC-1 to UTC+1 range, even if there should be such stations. One such station is the Troll station, which is operated year-around and belongs to Norway. I had a mail conversation with the responsible authority, the Norwegian Polar Institute, about which time zone the Troll station actually uses. The Troll station station officially uses UTC+0. During the dark season March-October, when no air or overland travel is done, it uses Norwegian summertime UTC+2 to simplify communication. So I suggest you add a new zone called Antarctica/Troll You may confirm this through Paul-Inge Flakstad at the Norwegian Polar Institute ( flakstad(a)npolar.no ) Yours Sincerely Bengt-Inge Larsson Sweden From: Paul-Inge Flakstad Sent: Monday, February 03, 2014 12:49 PM To: Bengt-Inge Larsson Cc: Nettredaktør Subject: RE: Time zone in Troll station Hi again Bengt-Inge, I can now confirm that Troll is indeed at UTC/GMT 0. Furthermore - should it be of interest to you - our overwintering team follow Norwegian time (including summer time) during the period they are alone at Troll (March-October). This practice is in place simply to make communication with the head office in Norway more convenient. Thank you for asking us about this. Questions like this and feedback in general are important factors in identifying weak spots in our information channels. In this case, we will update our website with more correct information about the Troll station. Best regards, Paul-Inge Flakstad From: Paul-Inge Flakstad Sent: 3. februar 2014 11:04 To: 'Bengt-Inge Larsson' Cc: Nettredaktør Subject: RE: Time zone in Troll station Hi again Bengt, I see now that my initial reply might have been misleading. Our website page about Troll (where I pulled the info from) states that "Troll is 2 hours after Norwegian time". With Norway in GMT +1, this would implicitly place Troll in GMT -1. However, I believe this is wrong, and that you are correct; Several reliable(ish) sources place Troll in GMT 0, and I assume they base this on geographical coordinates. This also fits nicely into the "2 hours behind"-info on our website, provided one is comparing to Norwegian summer time. I have sent an e-mail to our Antarctica department, asking for verification, and will come back to you with a definite answer as soon as I receive their reply. Best regards, Paul-Inge Flakstad From: Bengt-Inge Larsson [mailto:bengt-inge@tele2.se] Sent: 31. januar 2014 17:33 To: Paul-Inge Flakstad Subject: Re: Time zone in Troll station That has to be 2 hours behind Norwegian Summer time, because I see that the clock on the web camera photos are one hour behind the Central European Winter time. And some other source, unchecked reliability, says there is Greenwich Time in the Troll area. Or is it ? Bengt-Inge Larsson From: Paul-Inge Flakstad Sent: Wednesday, January 29, 2014 10:34 PM To: Nettredaktør ; Bengt-Inge Larsson Subject: SV: Time zone in Troll station Hi Bengt, Troll is 2 hours behind Norwegian time. Best regards,Paul-Inge FlakstadWeb developer, Norwegian Polar Instituteflakstad(a)npolar.no Bengt-Inge Larsson <bengt-inge(a)tele2.se>: Hello! Which time zone is kept at the Troll research station in Antarctica (what are the clocks there set at)? Or what is the time difference to Norway ? I ask since the time zone database used for computers contains some stations in Antarctica, only belonging to English speaking countries, USA; UK and Australia. But not Troll, and it seems that Troll is in some other time zone, since it is not located near those listed bases. Bengt Larsson Göteborg Sweden

Yes, I would, which suggests that a 'disputed' country is a bad idea, but that putting the zones in each country works better. It is important to NOT choose.

Would you mark "disputed" no matter who makes the claim of dispute? If yes, you would end up with so many entries that it becomes pointless. If no, then you're choosing authorities - those whose marking you would accept. Is South Korea disputed? Kim III would probably say it is. Is Taiwan disputed? Crimea?

Ukraine 1990, PS
by Bogdan Krusiński March 16, 2014

March 16, 2014

google translator gone mad - translates ukrainian word 'bes' ("without") as 's' ("with") (i tried both translating into polish and eglish, both translations are opposite to what was in orginal). The decree from june 1990 do not mentions previous zone - just states that country moves to zone +2 GMT without addition of one hour (without DST) ie +2 GMT. with best regards Bogdan Krusiński
