More Russian Changes
by Matt Johnson Nov. 25, 2015

Nov. 25, 2015

FYI - Two draft bills are posted on the Russian government's web site: http://government.ru/activities/20702/ http://government.ru/activities/20703/ If approved, the effect would be to move the Astrakhan region from UTC+3 to UTC+4, and to move the Trans-Baikal region from UTC+8 to UTC+9. Neither bill mentions an effective date. It's not clear whether the Trans-Baikal region refers to the entire area of Zabaykalsky Krai or some subset. Zabaykalsk Krai is currently managed by the Asia/Chita time zone, which I assume would remain intact and just get a new row in its zone entry. Also, assuming by Astrakhan region they mean the Astrakhan Oblast, then I think this change would require a new time zone. I suggest Europe/Astrakan for the city of the same name in this region. This is split from the Europe/Volograd time zone. -Matt

zoneinfo vs zoneinfo-leaps
by Ken Murchison Nov. 17, 2015

Nov. 17, 2015

Maybe this is a FAQ but I haven't found the answer. Having studied up the tzfile(5) format and written some code to produce these files, I'm wondering why the files in zoneinfo-leaps include the leap records AND adjust the transition times by the appropriate number of leap seconds. This seems redundant to me. If the file includes the leap second records, why not let the consumer adjust the transitions? -- Kenneth Murchison Principal Systems Software Engineer Carnegie Mellon University

America/Metlakatla now follows Alaska
by Steffen Thorsen Nov. 13, 2015

Nov. 13, 2015

It seems Metlakatla did go off PST on Sunday, November 1, changing their time to AKST and are going to follow Alaska's DST, switching between AKST and AKDT from now on. Based on: http://www.krbd.org/2015/10/30/annette-island-times-they-are-a-changing/ Best regards, Steffen Thorsen - timeanddate.com

A discussion on POSIX on new timezone related C APIs
by Random832 Nov. 12, 2015

Nov. 12, 2015

http://austingroupbugs.net/view.php?id=1005 The proposals seem to be: 1. Something involving integrating timezone information into locale_t 2. Something along the lines of NetBSD's _z/_rz functions The fact that no-one seems to have a reference C implementation of localizing time zone names/abbreviations also came up. I don't know how open they are to outsiders sticking their noses into the process though, just thought some people here might be interested. Also proposed is the addition of "tm_nsec" to struct tm, and the new APIs in one of the proposals use a struct timespec rather than time_t.

There is another - Tsay Keh Deme, about 86km to the south (56.892014, -124.963373). Population 245. I imagine it also observes Vancouver time. I have tried to reach out to the RCMP detachment office there via the "contact us" thingy on the RCMP website, but have not received any response. I didn't feel like making an international call. Their detachment webpage is: www.rcmp-grc.gc.ca/detach/en/d/212. If it's a free call for you, it may be worth giving them a ring. There area of coverage is basically the whole western part of the PRRD. I imagine they could speak with some authority about whatever time zone observances may be practiced throughout the area. But it has to be Pacific time - nothing else makes sense regardless of the opinion of the GIS folks at the PRRD. Their primary economic ties will be outside the PRRD to their south and west.
