Western Sahara
by Gwillim Law Oct. 23, 2013

Oct. 23, 2013

A correspondent who is usually well informed about time zone matters sent me a correction to my time zone data for Western Sahara. He says that Western Sahara observes daylight saving time, just as Morocco does. The tz database shows it as Africa/El_Aaiun with no DST. The status of Western Sahara is disputed, but Morocco has de facto control over some 80% of the territory, including El Aaiun (a.k.a. Laâyoune). It seems logical that the clocks would be set to the same time as Morocco. For what it's worth, the CIA World Factbook says that in Western Sahara, DST "begins last Sunday in April; ends last Sunday in September." If it can be confirmed that El Aaiun's time is the same as Morocco's, the Zone info for Africa/El_Aaiun should be changed to match Africa/Casablanca, at least after 1991-09-06 (the date of the cease-fire that ended the Western Sahara War), and possibly as far back as 1976-02-20 (the date when Spain abandoned its possessions there).

[PATCH 1/2] zdump: remove unportable assumption about sscanf and overflow

Oct. 20, 2013

* zdump.c (strtoimax) [!INTMAX_MAX]: Define like private.h does. (SCNdMAX): Remove; no longer used.

Acre, Brazil time zone change passed in Senate, waiting for President
by Steffen Thorsen Oct. 17, 2013

Oct. 17, 2013

According to multiple news sources, Acre and some western parts of Amazonas will probably change time zone later this year, going one hour back. The change has been approved in the senate, but the president could veto it, but that is unlikely to happen. The date for the change is not yet announced. Some sources in Portuguese: http://g1.globo.com/ac/acre/noticia/2013/10/senado-aprova-mudanca-de-fuso-h… http://agenciabrasil.ebc.com.br/noticia/2013-10-08/senado-aprova-projeto-qu… http://www.oriobranco.net/concursos/34175-acre-e-uma-parte-do-amazonas-deve… Our short summary, in English: http://www.timeanddate.com/news/time/acre-amazonas-change-time-zone.html Best regards, Steffen Thorsen - timeanddate.com

Antarctica/McMurdo
by Wolfgang Pausch Oct. 16, 2013

Oct. 16, 2013

Hello, in my application, I used Antarctica/McMurdo in some test case. In version 2013d, file antarctica contained an entry # # # McMurdo, Ross Island, since 1955-12 # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Antarctica/McMurdo 0 - zzz 1956 12:00 NZAQ NZ%sT which is gone in version 2013g. However, McMurdo is still referenced both in australasia in a link, and in the zone.tab file: ~/tmp/tzdata$ grep McMurdo * antarctica:# "in the US Camp (East Camp) we have been on New Zealand (McMurdo) antarctica:# McMurdo Station, Ross Island, since 1955-12 antarctica:# as supplies for the station were coming from McMurdo Sound, antarctica:# We use the same time as McMurdo does. antarctica:# See 'australasia' for Antarctica/McMurdo. australasia:Link Pacific/Auckland Antarctica/McMurdo zone.tab:AQ -7750+16636 Antarctica/McMurdo McMurdo, South Pole, Scott (New Zealand time) ~/tmp/tzdata$ I guess this is a inconsistency in the tzdata files...?

Hi Paul, thanks for referencing this, I hadn't spotted it until now. I assume Mike Douglass and Cyrus Daboo subscribe to this list? Great work - at first read the only thought I had was that JSONP should be supported.

[PATCH 0/4] Make tzselect more portable
by Patrick 'P. J.' McDermott Oct. 6, 2013

Oct. 6, 2013

These patches allow tzselect to run on almost any Bourne-compatible shell (tested: bash, BusyBox ash, dash, ksh93, mksh, pdksh, posh, yash, and zsh) and fix an issue with older versions of BusyBox awk (and makes the setting of FS more consistent throughout tzselect). The prompts are identical to those printed by ksh or bash, except that the final prompt now gives a more generic error message than the old "Please enter 1 for Yes, or 2 for No." message. I hereby disclaim copyright interest in these changes. -- Patrick "P. J." McDermott http://www.pehjota.net/ Lead Developer, ProteanOS http://www.proteanos.com/
