Thanks Deborah! Is theee any way you could get Apple to post this somewhere official? Preferably there would be a page somewhere with each OS version and corresponding tzdb version, that gets maintained.

Acknowledged. Thanks for the clarification. -Matt ________________________________ From: Paul Eggert<mailto:eggert@cs.ucla.edu> Sent: ‎10/‎27/‎2015 10:31 AM To: Matt Johnson<mailto:mj1856@hotmail.com> Cc: Time Zone Mailing List<mailto:tz@iana.org> Subject: Re: [tz] America/Santa_Isabel Matt Johnson wrote: > there is a corresponding entry in Windows, "Pacific Standard Time (Mexico) |(UTC-08:00) Baja California" I'm afraid this will have to be adjusted on the Microsoft end. There needs to be a procedure for removing time zones that turn out to be mistakes. America/Santa_Isabel is a mistake, and I suppose we can view this as an opportunity for ironing out any procedural glitches while removing it. We do have a backward compatibility link on the tzdata side; perhaps that will help for the Microsoft side. > Also, there's a chance that San Quintin could indeed start using Mexican DST rules in 2017, We can create a zone America/San_Quintin if that happens.

News: Alaska modifies SB 6, holds working session
by Ray at the Time Zone Report Oct. 31, 2015

Oct. 31, 2015

Just when I thought all DST bills for the 2015 US state legislatures were way past their shelf life. Alaska is revising its SB 6 and holding a working session this morning pm the bill. Details from the AK legislature web site here: http://www.legis.state.ak.us/basis/get_complete_bill.asp?session=29 <http://www.legis.state.ak.us/basis/get_complete_bill.asp?session=29&bill=SB 6> &bill=SB6 There appear to be two provisions of SB 6: 1. Exempt the entire state from DST, regardless of time zone boundaries 2. Petition the US Department of Transportation to move all of Alaska into the Pacific time zone. The effective date listed is January 1, 2017. Plenty of time - if this goes through.

News article: Turkey’s plan to ignore daylight saving time has been foiled by smartphones
by Philip Newton Oct. 31, 2015

Oct. 31, 2015

http://qz.com/533126/turkeys-plan-to-ignore-daylight-saving-time-has-been-f… Turkey, like other countries on Eastern European Time (EET), was supposed to turn its clocks back by one hour on Sunday (Oct. 25) for the annual end of daylight saving time—or, as it’s known in Europe, “summer time.” But this year, the Turkish government told citizens to wait until Nov. 1 to allow more hours of light for voting in the nation’s upcoming parliamentary elections, reports the BBC. However, anyone who uses internet- or radio-connected mobile devices or computers to tell time knows that those clocks sync automatically to international standards. Today, Oct. 26, many people in Turkey with the latest Apple, Android, and Windows devices woke up with their clocks an hour slower than the government’s. The hashtag #saatkac (“what’s the time”) is trending among Twitter users in the country. The government has done this before for national elections and university entrance exams, in each case delaying the clock changes by one day. This year, however, Turkey has asked citizens to wait 14 days before turning their clocks back. For the next two weeks, then, the country is on “Erdogan Time,” a national joke and a nod to president Recep Tayyip Erdogan’s paternalistic reputation.

Re: [tz] timezone change for antarctica\casey [SEC=UNCLASSIFIED]
by Michael Chinn Oct. 31, 2015

| Can we now assume, do you think, that Casey will be switching back and forth between +0800 and +1100 in accordance with Australian summer time shifts for the forseeable future (that 3 hour offset change will break assumptions made in some code I expect!) The TZ changes, particularly at Casey, are highly variable, they are based around resupply and flights. They will rarely line up with DST changes, this year there were early flights (leaving tomorrow) and an early insertion of ground crew into Wilkins | What's useful to know is when it was first founded/settled, what times were in use locally, when they altered (as accurately as possible) and what the prediction is for the future. I will endeavour to go through the database and pull out the TZ changes, should be able to get 3-4 years. Regarding predictions, sometimes there are only a couple of days notice on changes much to the anguish of a few wintering expiditioners. All changes are visible live on the external site (it's the same database) ___________________________________________________________________________ Australian Antarctic Division - Commonwealth of Australia IMPORTANT: This transmission is intended for the addressee only.

timezone database isn't everywhere yet
by Arthur David Olson Oct. 30, 2015

Oct. 30, 2015

I serve on the board of elections for Takoma Park, Maryland, USA.. Early voting in our city election started on 2015-10-28; election day is 2015-11-03. The city uses county-provided electronic poll books to track who has voted. Two were in use on the 28th. I noticed that they were showing times that differed by an hour. I inquired about it; I was told it was deliberate, and was because daylight saving time was in effect when voting started whereas standard time will be in effect when voting ends. If only we had a way for gizmos to automatically switch the clock when daylight saving time ends.-S @dashdashado

tzdata isstd question
by Ken Murchison Oct. 30, 2015

Oct. 30, 2015

All, Given the following zone: Zone America/Atikokan -6:06:28 - LMT 1895 -6:00 Canada C%sT 1940 Sep 29 -6:00 1:00 CDT 1942 Feb 9 2:00s -6:00 Canada C%sT 1945 Sep 30 2:00 -5:00 - EST I'm wondering why the transition on Feb 9, 1942 isn't flagged as being observed at standard time in the compiled tzfile. Does the time suffix in UNTIL not get applied to the following transition? -- Kenneth Murchison Principal Systems Software Engineer Carnegie Mellon University

include implementations of str{f,p}time{,_l} in tzcode
by christos＠zoulas.com Oct. 30, 2015

Oct. 30, 2015

Hello, I think that it is an omission for those functions not to be included in tzcode. They are tightly bound to the rest of the time code implementation and although standardized, the implementations that the most popular operating systems provide vary in behavior. Yes, I understand that there are portability considerations (locale for example) that need to be handled, but not including them is taking the easy way out. Best, christos

Hi, Im not too sure on the correct formatting for submitting changes to tzdata, or if the Antarctic tzdata is still being maintained? There is a change for the Australian Antarctic zone Antarctica/Casey went to +1100 for Summer operations on Sunday 04 October at 2am. Source: http://www.antarctica.gov.au/living-and-working/stations/weather and internal emails Also, there is an location for Wilkins Aerodrome that technically can have its own timeone separate from Casey. If it is useful I can get some historical dates?

Official definition and origin of the term "Central European Time"
by Even Scharning Oct. 29, 2015

Oct. 29, 2015

Is there an official definition of the term "Central European Time" (CET), specifically which UTC offset(s) it refers to? If there is no official definition, where did the term originate from? I asked the information desk at the EU (Europe Direct) to help me find links to relevant legislature, but their reply was that term CET is "not regulated at a EU level, but internationally". All credible sources I have found, say that CET is a constant UTC+1. The closest thing I have found to an authoritative document, is the German Time Act from 1978. It says: "Legal time is Central European Time. It is defined as Coordinated Universal Time plus one hour." There is no reference to the origin of this definition, and no information of whether anyone other than the Germans agree on this definition. http://www.cl.cam.ac.uk/~mgk25/time/zeitgesetz.en.html On the EU's web pages (for instance http://europa.eu/contact/index_en.htm) times are usually given in CET, not CEST (Central European Summer Time), even though daylight saving time is currently observed. Google gives a few hundred thousand results for CET on europa.eu, and numerous of these results are hits on dates in the daylight saving time period. I think it makes more sense to define CET as alternating between UTC+1 (standard time) and UTC+2 (when DST is observed). (See http://time.is/CET for a more elaborate definition.) This is in line with for instance the US time zones Pacific Time and Eastern Time, which refer to the time currently observed, whether it is standard time or daylight saving time.
