temporary timezone database home ...
by Robert Elz Oct. 21, 2011

Oct. 21, 2011

First, I am assuming this copy of the list is actually functioning, (and I've just received jhawk's message which demonstrates that it is) I don't believe it has been used for actual messages before that one, but as ado has indicated that the list at elsie has been (for now anyway) terminated - and given the plan was to migrate from it eventually anyway, may never return, we can but hope this version of the list is functional. Some of you who receive this message may have been removed from the elsie version of the list recently, or altered your subscription details - if that applies to you, use the iana.org message sent on the 1st of this month to all subscribers to their list for instructions on how to modify or delete your subscription. Don't send requests to me (or anyone else on the list) there's nothing I (or we) can do about it - and most certainly, do not send requests to the list itself asking to be removed. Unfortunately, there are probably a few people who were added to the elsie list since it was cloned at iana.org but there's nothing much we can do about that - if anyone is contacted by anyone who believes they should be on the list, but is no longer receiving messages, direct them to the iana website for list subscriptions. Next, while elsie's ftp server is shut down, munnari.oz.au isn't, and the tz database & code remains available from here. Further, I will not respond to requests from (almost) anyone to cease making those files available (including Arthur and Paul - but by all means feel free to try if you need to to satisfy some obligation to cease making the data available - I'll ignore you, but you will at least have used every reasonable effort...) Second, regardless of this, the world's governments continue to adjust their view of their local timezones & summer time adjustments, so we need to continue updating the database (at least). There are several updates that will be needed soon. For now, until someone else volunteers, I'm prepared to make the updates, in much the same way that Arthur did, and then make new releases available from munnari's ftp server. I suspect that it is unlikely that either Arthur or Paul will be able to assist much with this in the coming months, so I'm hoping that others will assist where possible. For now, I'm aware of changes needed for Armenia, Fiji, Bolivia, Brazil, and of course, the changes that (might be) needed for Russia. If there's anything else I missed, please let me know. Unfortunately, I don't have the sccs (or is it rcs or something these days) master files, so I won't be able to do quite the same job that Arthur did, but I can keep all versions so they can be checked into a version control system later. It would be good if a few others, especially people in jurisdictions that tend not to simply bow down to US court rulings, would keep copies of the code and data, and make them publicly available via ftp or http (this is not of huge public interest, the resources needed to provide this service should not be very noticeable). All I know of the lawsuit is what jhawk's message indicated - eventually I assume we'll find out what trademark or patent that someone believes is being infringed (a little hard to believe either, but who knows...) The URL's of the current versions of the files from munnari.oz.au are ... ftp://munnari.oz.au/pub/tzcode2011i.tar.gz ftp://munnari.oz.au/pub/tzdata2011k.tar.gz and of course, the historical files (most versions that were ever previously released) are in ftp://munnari.oz.au/pub/oldtz/ kre

I hate to throw a spanner in the works, and I do think KRE is right for the job, but are we all certain he even wants this greatness thrust upon him?

Although the draft (it will be published as a RFC) discusses the role and responsibilities, it is more about the TZ community using its best judgement to keep up the good work that was started by Ado. Robert commented on the current work ( http://mm.icann.org/pipermail/tz/2011-October/008093.html ). I think that the message at http://mm.icann.org/pipermail/tz/2011-October/007993.html summaries the tone to expect from the TZ community. Regards, -sm

time zone suggestions
by Steven Abner Oct. 20, 2011

Oct. 20, 2011

Hi Not sure if I should contact the organization or Zefram. But it looks like the new management might be open to some queries and/or options from outside sources. This information pertains to northamerica, and one was accepted by you already, where Mr. Olson implied it was correct, so you may have to alter the information I am supplying. They are suggestions only, and were done to aid parsing of the tz data, different parser with more strict rules for converting. Feel free to ignore, or pick out what you feel relevant, as only the Sitka change was of any real importance. The Anchorage one was to keep the northamerica rules from needing the translation unit of the europe file rules, which I altered to follow the majority of your data files. This is one of the patches I use to set your data to my data. Sorry to intrude, Steve

Ukraine to keep winter time after all
by Philip.Pizzey＠sita.aero Oct. 18, 2011

Oct. 18, 2011

Hi there, I've been following the recent discussions on this list about the timezone changes in Ukraine, Russia and Belarus. Today my Ukrainian colleagues have informed me that the Ukrainian parliament have decided that they will go to winter time this year after all. Please see the following link: http://portal.rada.gov.ua/rada/control/en/publish/article/info_left?art_id=… > > The Verkhovna Rada of Ukraine Resolution "On changing the Order of Computation of Time in the Territory of Ukraine" No. 3755-VI of September 20, 2011 was declared invalid. > Cheers, Phil.

Short notice: Ukraine invalidates law to introduce permanent DST
by udo.schwedt＠obi.de Oct. 18, 2011

Oct. 18, 2011

As far as I understand, the recent change to the Ukranian time zone (Europe/Kiev) to introduce permanent daylight saving time (similar to Russia) was reverted today: http://portal.rada.gov.ua/rada/control/en/publish/article/info_left?art_id=… AFAICS, this means that the current Kiev time zone (UTC/GMT +3 hours) will be changed back to former Ukrainian standard time (UTC/GMT +2 hours) by the end of this month (October 2011). Thus the original DST rules (that were changed with tzinfo2011k) will have to be restored. I don't know how such near-term situations are usually handled (I'm fairly new to this list), but I'd like to bring this to your attention and propose a change at short notice.

Proposed time zone package changes (Fiji, Bahia Brazil, West Bank(Hebron))
by Robert Elz Oct. 17, 2011

Oct. 17, 2011

Here are proposed changes to the time zone package. I'm releasing these changes now as the change to Bahia, Brazil, is due to take effect next Sunday week (8 or 9 days away, or something), so getting at least that change distributed now is urgent. The executive summary asia Changed the end date for Summer Time for this year (2011) to match reality reported by Steffen Thorsen. northamerica Corrected typo in (ancient) LMT zone offset as detected by Zefram. southamerica Resume Summer Time in Bahia, Brazil (following the standard Brazil algorithm, which causes Summer time to start Oct 16 this year, which matches the report.) australasia Adjust the end date for Summer time in Fiji in 2012 (Feb) as reported by Steffen Thorsen. That Bolivia will not start Summer time this year seems fortuitous as apparently we had no idea that it had been intended. Armenia's plan to abolish Summer Time can wait until it has ceased being a plan and become reality. As with Arthur's last update, any changes needed for Russia are deferred, mostly because I haven't been able to fathom what those changes need to be... (I wasn't paying that much attention to all the messages about this, as I didn't expect any of that to directly affect me - if someone who knows what is happening could send a proposed diff, that would help). One proposal that Arthur, Paul, and I had kicked around a little (very little) off list that might affect things there, was to abandon attempts to invent new time zone abbreviations for places that don't have one already in use, and instead just insert LST as a place holder (Local Standard/Summer Time). Anywhere that cares what the abbreviation is can have their preferred abbreviation, as always, other places, where we had been inventing strings just because we thought it was a good idea, will get LST instead. There was no plan to go back and change all the currently established invented abbreviations though, or not unless there's a request to remove a particularly poor choice, if we have any of those. And yes, we know that LST already exists with another interpretation (which can remain), we don't care. None of this is in this update, so feel free to express opinions on the advisability of adopting this policy for future new zones. The tzdata diff follows. I plan on releasing this next Monday (October 10) if there are no detected problems (and will almost certainly release whatever part of this is correct then). Note that I life in a timezone far east of Arthur, his Monday updates got to me on my Tuesday, so my Monday update will get to many of you on your Sunday.... kre *** asia 2011/10/07 06:09:10 1.1 --- asia 2011/10/07 06:54:28 *************** *** 2269,2275 **** 2:00 Palestine EE%sT 2011 Apr 1 12:01 2:00 1:00 EEST 2011 Aug 1 2:00 - EET 2011 Aug 30 ! 2:00 1:00 EEST 2011 Oct 3 3:00 2:00 - EET # Paracel Is --- 2269,2275 ---- 2:00 Palestine EE%sT 2011 Apr 1 12:01 2:00 1:00 EEST 2011 Aug 1 2:00 - EET 2011 Aug 30 ! 2:00 1:00 EEST 2011 Sep 30 3:00 2:00 - EET # Paracel Is *** australasia 2011/10/07 06:09:10 1.1 --- australasia 2011/10/07 06:21:11 *************** *** 303,308 **** --- 303,310 ---- Rule Fiji 2010 only - Mar lastSun 3:00 0 - Rule Fiji 2010 only - Oct 24 2:00 1:00 S Rule Fiji 2011 only - Mar Sun>=1 3:00 0 - + Rule Fiji 2011 only - Oct 23 2:00 1:00 S + Rule Fiji 2012 only - Feb 26 3:00 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Pacific/Fiji 11:53:40 - LMT 1915 Oct 26 # Suva 12:00 Fiji FJ%sT # Fiji Time *** northamerica 2011/10/07 06:09:10 1.1 --- northamerica 2011/10/07 06:13:35 *************** *** 483,489 **** -8:00 US P%sT 1983 Oct 30 2:00 -9:00 US Y%sT 1983 Nov 30 -9:00 US AK%sT !

Irish time...
by Kevin Lyda Oct. 17, 2011

Oct. 17, 2011

The first entry in the europe zone file for Ireland is as follows: Rule GB-Eire 1916 only - May 21 2:00s 1:00 BST However I don't think it's correct. I'm not sure how far back we want to go, but apparently from 1880 up until October, 1916, Dublin was 25 minutes off from London. When the clocks were set back in October 1916, they were set back 35 minutes - which would seem to cast doubt on the second line for GB-Eire: Rule GB-Eire 1916 only - Oct 1 2:00s 0 GMT And 25 minutes, as noted in the file was an oversimplification. A web page with more detail is here (I've cc'd Dave who might have more info): http://www.maths.tcd.ie/~dwmalone/time/dunsink.html And apparently there were places in Ireland observing the Dunsink based "Dublin Mean Time" up to the 1940s: http://historical-debates.oireachtas.ie/D/0079/D.0079.194003050027.html In addition, Belfast seems to have had yet another timezone.
