Re: [tz] Tennessee time

I think the fact that they could choose to call their resulting UTC-4 time zone "EDT" rather than "AST" probably wouldn't be in violation of the Uniform Time Act (but I'm not a lawyer either). That said, the federal Department of Transportation (which apparently has jurisdiction over such things) hasn't allowed Maine to move to Atlantic Time, so the odds that they'd allow Tennessee to do so seem rather low. (If Maine does ever manage to move its time zone, naming its zone identifier is going to be an interesting challenge for the TZDB -- since "America/Portland" is rather unfortunately ambiguous...) -- Jonathan Lennox lennox(a)cs.columbia.edu

timezone 2014 : Turkey delays DST start by one day
by Semih Sakiz Feb. 27, 2014

Feb. 27, 2014

Hello, According to Turkish government decision, there will be one-day delay in the start of DST. DST start time will be "2014 Monday, 31 March" instead of "2014 Sunday, 30 March" on Turkey. Is there a plan to update the time zone database for this change ? The latest timezone data on the URL "http://www.iana.org/time-zones" contains Time Zone Data v. 2013i and does not include the latest change in TURKEY.

Nothing official has been announced at: http://www.horaoficial.cl/cambio_hora.html A quick search of newspapers for 'horario de invierno' also turns up nothing. However, keep in mind that Chile is in the midst of a government change; the inauguration of the new government is 11 March, and IIRC if the old government does nothing, the time change reverts to the old rule (March 8). I have no idea what to do about this. I knew making the new rule permanent would cause trouble. -G.

posix timestamp compatibility library for systems using right timestamp
by Marek Behun Feb. 12, 2014

Feb. 12, 2014

Hello, I have written a small POSIX timestamp compatibility library for glibc/linux systems which use right timestamp on system clock (and also a 'right/' timezone). By executing a program with LD_PRELOAD=/path/to/time2posix.so environment variable the program can still use a 'posix/' timezone and display system time correctly (system calls for getting/setting system time are patched byt time2posix.so). I wrote this library primarily for synchronizing time from NTP servers that use UTC. This way, when using for example ntpdate to synchronize from such a server, ntpdate doesn't have to be patched to synchronize to right timestamp (instead of posix). The library could also be used on programs that cannot use 'right/' timezone (for example PostgreSQL can't handle leap seconds and therefore won't accept a 'right/' timezone in configuration). For that though more system call patches need to be implemented. The sources can be found at https://github.com/elkablo/time2posix I would like to know if I should continue developing this library or if there are other ways of synchronizing to right timestamp correctly, or if right timestamp and consequently right timezones aren't used at all.

Glibc 2.19 adds support for version 3 tz format
by Paul Eggert Feb. 12, 2014

Feb. 12, 2014

The GNU C Library version 2.19, released February 8, adds support for version-3 format tz binary files. I thought I'd give this list a heads-up, in case other C-library maintainers are lurking and want to keep up with the Joneses. As you may recall, version 3 is a minor extension to the binary format, which adds support for some less-common timekeeping practices. So far, the only tz-database timestamps affected by this change are time stamps after the year 2037 in America/Godthab with tz data 2013e or later. These time stamps cannot be described by a POSIX TZ string, so version 3 uses the quasi-POSIX string 'WGT3WGST,M3.5.0/-2,M10.5.0/-1'. The glibc 2.19 announcement is at <https://sourceware.org/ml/libc-alpha/2014-02/msg00224.html>. More details about this change can be found at <https://sourceware.org/bugzilla/show_bug.cgi?id=15968>.

question about Asia/Urumqi: why Guangdong
by Alois Treindl Feb. 3, 2014

Feb. 3, 2014

In the commentary for zone Asia/Urumqi one reads # Xin-zang Time ("Xinjiang-Tibet Time") # The Gansu counties Aksay, Anxi, Dunhuang, Subei; west Qinghai; # the Guangdong counties Xuwen, Haikang, Suixi, Lianjiang, # Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, and Xinyi; # east Tibet, including Lhasa, Chamdo, Shigaise, Jimsar, Shawan and Hutubi; # east Xinjiang, including Urumqi, Turpan, Karamay, Korla, Minfeng, Jinghe, # Wusu, Qiemo, Xinyan, Wulanwusu, Jinghe, Yumin, Tacheng, Tuoli, Emin, # Shihezi, Changji, Yanqi, Heshuo, Tuokexun, Tulufan, Shanshan, Hami, # Fukang, Kuitun, Kumukuli, Miquan, Qitai, and Turfan. Question: what is the rationale for having the Guangdong counties listed for this zone? Guangdong is the province around Hongkong, with latitude around 20n and longitude around 115e. This is geographically very far away from east Tibet and east Xinjiang, altitude around 40n and loangitude less than 82e. What is the source for listing Guangdong here? I presume that this is an error.
