proposed time zone package changes (Samoa, Factory, et al.)
by Arthur David Olson 28 Aug '19

28 Aug '19

Below find proposed time zone package changes; the executive summary: * Makefile Change LOCALTIME default from "Factory" to "GMT"; do not compile "factory" file (but keep it in the distribution). * Theory Remove reference to "Factory" zone. * australasia Change end of DST in Samoa in 2011 from 2011-04-03 0:00 to 2011-04-03 1:00 (thanks to Raymond Hughes for a reference). * localtime.c Initialize ttinfo structures filled by tzparse (thanks to Ravindra for reporting a valgrind warning). * zic.c Fix generation of POSIX strings for zones with rules using "weekday<=n" forms of dates (thanks to Lei Liu for finding the problem). Also, limit output for non-POSIX-specificable zones defined to follow the same rules every year. (Note that no zones of either of the above types appear in the distribution; these changes cater to add-on zones). If no problems are found, 2010n will appear on 2010-10-25. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Mon Sep 27 09:24:25 2010 --- new/Makefile Tue Oct 12 12:36:50 2010 *************** *** 1,5 **** # <pre> ! # @(#)Makefile 8.8 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)Makefile 8.9 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 12,18 **** # make zonenames # to get a list of the values you can use for LOCALTIME. !

Jeopardy! category on time zones 2019-05-28
by Tim Parenti 24 Jun '19

24 Jun '19

Apparently there is a category on time zones on the US version of *Jeopardy!* tonight (Tuesday 28 May). I'll avoid any spoilers for now — due to the vagaries of US broadcast syndication and, well, time zones — for anyone stateside who might be as captivated by the performance of the current champion, James Holzhauer, as my friends. I'll try to send over the clues tomorrow. -- Tim Parenti

UTC calculation for March 12, 3001 [IANA #1143241], [PR 9419866]
by Lasher, Beth 10 Jun '19

10 Jun '19

In the year 3001, Daylight Savings time is applied on Sunday March 9, 3001 as expected. (Eastern Standard time). BUT on the following Thursday, March 12, 3001 at 3 am, it seems that another Daylight Savings Time change is applied. After March 12, 3001, the UTC time zone offset for Eastern Daylight Savings Time is 3 hours (not 4) and remains that way until the year 9999. Is this correct? What is the cause of this second time offset change?

Fwd: Historical timezone data for Bonin Islands (Ogasawara)
by Phake Nick 29 May '19

29 May '19

Hello all, I have recently received some new information about timezone history of Bonin Islands, Japan as detailed in the attached message. Because their last time change to return to Japanese time when they return to Japanese rule was right before 1970, it mean per the current tz database rule, the information doesn't warrant creation of a new timezone for Bonin Islands itself and is thus as an anecdotal note for interest purpose only. However, in the attached link, it described some special timekeeping phenomenon regarding Marcus island, another remote island currently owned by Japanese in the same administrative unit as Bonin Islands. Many reports claim that the American coastal guard on the American quarter of the island use its own coastal guard time, and most sources describe the time as UTC+11, being two hours faster than JST used by some Japanese personnel on the island. Some sites describe it as same as Wake Island/Guam time although it would be incorrect to be same as Guam. And then in a few Japanese governmental report from 1980s (from National Institute of Information and Communications Technology) regarding the construction of VLBI facility on the Marcus Island, it claimed that there're three time standard being used on the island at the time which include not just JST (UTC+9) or [US]CG time (UTC+11) but also a JMSDF time (UTC+10) (Japan Maritime Self-Defense Force). Unfortunately there are no other sources that mentioned such time and there are also no information on things like how the tine was used. ---------- Forwarded message --------- From: Wakaba Date: 2019-1-28 Mon 13:48 Subject: Re: Question related to the page 昭和のサマータイム on suikawiki To: Phake Nick >> Hello, I see that there're a lot of information about DST at the time in Japan on Suikawiki, but a special area that's not mentioned in the page os Ogasawara 小笠原諸島 (Bonin Islands) which seems to have its own different history of governance. Do you know where can information related to timezone of the islands can be found? > Unfortunately we have no reliable source on time in US-controlled Ogasawara Islands at the moment. It turns out that National Diet Library of Japan has several reports by Japanese Government officers that describe the time used in islands when they visited there. According to them (and other sources such as newspapers), standard time UTC + 10 (JST + 1) and DST UTC + 11 (JST + 2) was used until its return to Japan at 1968-06-26 00:00 JST. The exact periods of DST are still unknown. I guessed Guam, Mariana, and Bonin and Marcus districts might have synchronized their DST periods, but reports imply they had their own decisions, i.e. there were three or more different time zones.

If it's that important for newlib perhaps we should just make it the default, under the argument that a POSIX-compatible prediction, even if wrong during Ramadan, is better than no prediction at all (as that will cause these clients to be wrong the whole year).
