Could you name what areas you refer to, so people can search more precisely for what you want to know? Which reports do you refer to? In 2011 there were talks on the mailing list about issues with Yakutia and with Sakhalin. I myself did suggest new zones that may be needed, given the old information in the tzdb was correct: http://mm.icann.org/pipermail/tz/2011-September/008799.html > 2. In 2010 much of Russia did not turn its clocks back in the fall. Can you cite a reference for that claim? > Does > anyone know whether folks in Russia now think of themselves as being on > "permanent daylight saving time" or think of themselves as having new, > different standard times? "folks" sounds quite unspecific. Do you mean people living in areas that "did not turn its clocks back in the fall" as claimed in the first sentence? -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com

Samoa error in backward file
by Timo Kähkönen April 7, 2012

April 7, 2012

Hi, I downloaded the file ftp://ftp.iana.org/tz/tzdata-latest.tar.gz and noticed one error in a text file named "backward". Backward file has two zones, which both link to Pacific/Pago_Pago. These are the two rows: Link Pacific/Pago_Pago Pacific/Samoa Link Pacific/Pago_Pago US/Samoa I'm not sure, but I assume that the record is wrong. There are two countries: 1. Samoa (WS), which Capital is Apia. Timezone UTC+13, Summer Time UTC+14 (Note! The same offsets than in Pacific/Apia) 2. American Samoa (AS), whose capital is Pago Pago. Timezone Samoa Standard Time (SST), UTC-11 (Note! THe same offsets than in Pacific/Pago_Pago. So, I assume that the rows should be: Link Pacific/Apia Pacific/Samoa Link Pacific/Pago_Pago US/Samoa Please correct if I'm wrong. Timo Kähkönen

Paul Eggert as new coordinator?
by Arthur David Olson April 7, 2012

April 7, 2012

I've been in touch with Paul Eggert; Paul is willing to serve as time zone coordinator. Paul has been part of the time zone community since the early 1990s; folks can read the database files to see the depth of Paul's involvement. I'd appreciate reactions to Paul's offer; please respond within the next week. (I hope to have a new coordinator in place sooner rather than later.) --ado

tzdata2012c released
by Robert Elz April 2, 2012

April 2, 2012

The file ftp://munnari.oz.au/pub/tzdata2012c.tar.gz is now available. This reflects the changes circulated last week by the tz co-ordinator (Arthur David Olson). Just in case it isn't obvious, this is a data only update (no code changes) tzcode2012b remains the current code version. The executive summary of the changes: africa Summer time changes for Morocco (to start late April 2012) asia Changes for 2012 for Gaza & the West Bank (Hebron) and Syria northamerica Haiti following US/Canada rules for 2012 (and we're assuming, for now anyway, for the future). Crypto hashes using several algorithms from NetBSD's pkgsrc digest program are appended, you can use these to verify that you have successfully fetched the same file that I intended to distribute (which is a tar.gz file that ado sent me to distribute). A few words on the logistics of all of this ... my term maintaining this stuff ended when ado & Paul returned after the law suit was withdrawn. For now, Arthur is the co-ordinator again, but as you have all seen on the list, the plan is for Paul to take over soon, in accordance with Arthur's long stated plan to retire sometime this year. The files are still being distributed from munnari.oz.au as (as I understand it) elsie is no longer available for this function, and arrangements to make it convenient to use the IANA site as a distribution point will probably not be made until after Paul has taken over. I expect the file will be copied to the IANA site sometime later today. kre MD5 (tzdata2012c.tar.gz) = cfdc2710bd05c26dbd624441d57028f6 RMD160 (tzdata2012c.tar.gz) = cf38b711231e0ddba2b4c0f7be4d18658d751774 SHA1 (tzdata2012c.tar.gz) = e0cd9c2cc0ac8d90ed842133b910d4bb3bc1a6dd SHA512 (tzdata2012c.tar.gz) = c43630f0bf1973b368229c788da90965d7c8b0d6dc8aa0f4bcbfac018a8c8291e1eb21cae05282df2eba6ec9a647c53c02fd92fea91fd5cb93855808387e52b9 TIGER (tzdata2012c.tar.gz) = 75f21b8b8645630cf679fbdd37f5d5789ace4ad69ebe9f26 WHIRLPOOL (tzdata2012c.tar.gz) = 119d8076a88287eb5063bd977aa63eaf918310e33b1d1f4fc60ad9ad72ed9b1d62918345e6f5786ca0ce6d5b938db1e33d05c0bdfdf70d1bd22a10ee825cf99d

Gaza and West Bank starting DST on Friday

Lots of things happening recently... Palestinian news sources tell that both Gaza and West Bank will start DST on Friday (Thursday midnight, 2012-03-29 24:00).

In reply to: [tz] Eternal DST rules for Morocco from 2012 at last Arthur David Olson arthurdavidolson at gmail.com Wed Mar 21 11:09:40 UTC 2012 I've attached an updated proposed change for Morocco; the tabs-mangled-by-Gmail version appears below. The differences are against 2012b. --ado diff -r -c old/africa new/africa .............. etc. Reply: In Morocco DST will not be observed during the month of Ramadan. This will happen approximately from 2012-7-20 to 2012-8-18. See my posting from a couple of days ago (Mar 16). Your TZ update does not reflect this situation. Any reason why? Oscar van Vlijmen

Easy conversion to MySQL?
by Yann Gascard / VPA President March 21, 2012

March 21, 2012

Hello, I'm normally using MySQL timezone description table (http://dev.mysql.com/downloads/timezones.html) But lately they are not that reactive there. Is anybody able to help me finding a way to generate these description table easily by myself? I got to use them as hosting provider I've got is not updating PHP timezones and I need an up to date reference. I don't have a Unix system. I can access to a Mac OS X one but even this one is really out of date (even with a system up to date). So I can't generate the tables using the mysql_tzinfo_to_sql there either :(** <http://dev.mysql.com/doc/refman/5.5/en/mysql-tzinfo-to-sql.html> Thanks a lot! :) -- -- *Yann Gascard* - President Virtual Pilots Association www.virtualpilots.org <http://www.virtualpilots.org>

Let me know what you are looking for. Hi David, Thanks for responding, and sorry I have been so slow in getting back to you (work travel the past few weeks; just now catching up). The Windows app looks terrific, but my little project will need to run on a small embedded Linux board (Gumstix Overo or similar), so I think it's really the internal engine I would want to use. (And in case it matters, this is a one-off personal project I'd been thinking of doing for some time now, so it's strictly non-commercial.) Regards, --HJ

TZ from lat/lon?
by H J March 20, 2012

March 20, 2012

Hello all, Not sure if this is the best place to ask this (and if not, I would be very thankful for any suggestions), but does anyone know of a decent open source lat/lon-to-timezone package that runs _standalone_ (as opposed to querying a server somewhere)? I am aware of a few networked solutions (e.g. earthtools) and at least one commercial package (askgeo). The former won't work standalone, while the site license for the latter is too steep for my noncommercial, one-off project. Thanks very much in advance, HJ

TZ Coordinator candidate
by Zefram March 17, 2012

March 17, 2012

With ado's retirement now almost upon us, I'd like to volunteer for the role of TZ Coordinator. Although I've only been directly involved, on the mailing list, for half a year, I've been peripherally involved for much longer. I'm very comfortable working in this space, and I believe I have the right personal qualities for the job. Firstly, I have a strong and unshakeable inclination to attend to detail, a determination to be thorough, and a decisive concern for correctness. (The former, at least, is an autistic trait, one of several that turn out to be useful to engineers.) I believe these qualities have been apparent in my contributions to the mailing list in recent months. For further substantiation, see my published code and contributions to other mailing lists (links below). I have a calm temperament, which kre rightly identified (on 2009-09-04) as a vital quality for this role. This can be seen in action on the various other mailing lists that I have inhabited in recent years. Particularly see the leap seconds mailing list, where in the past couple of years many discussions have regrettably become much more heated than befits the calibre of participant, and perl5-porters, where I've occasionally dealt with a prickly CPAN author. I'm at the right point in my career to take on this sort of role, potentially for as long as ado has served. I'm mature enough to take on a long-term commitment, while still young enough to have a long term. I was born in 1977, and so am some thirty years away from pensionable age. I can't promise to actually serve for that long, but there isn't anything standing in the way of me doing so. I have, and use, network access nearly every day, so I can respond promptly to urgent issues. I read email, as it comes in, during most of my waking hours, and I'm similarly available on IRC. I tend to spend my weekends and holidays (from paid work) programming. I don't make a habit of travelling, though I presently attend an annual conference that occupies me for five consecutive days. (I haven't so far attempted to access the net while at a conference, but it is available at these conferences, and I ought to get with the times.) Although it's not strictly necessary in a TZ Coordinator, I'm technically well qualified to look after the timezone code. C was my main programming language for about ten years, 1988 to 1998. Since then my main language has been Perl, but I still regularly work in C. About half of the Perl modules that I've published are largely implemented in C, for one reason or another, and I'm a contributor to the Perl core, which is written in C. The quality of my code can be discerned by perusal of my published Perl modules. I have a deep and abiding interest in horology, and particularly in computer implementation of it. I've been on the leap seconds mailing list for some years, actively involved in many discussions there. In the Perl world much of my published code is concerned with time, and last year I gave a well-received talk about time (but not timezones) at two Perl conferences (video link below). Looking more specifically at timezones, some of my Perl code is about timezones, much of that specifically about using the TZ database. I've become intimately familiar with the database through my work on this code. As a bonus, I have some plans for how the database should develop from where it is now. Chief among them, I'd like to see it become more historically comprehensive, but there are obvious problems for users that would come from multiplying up the number of timezones on the present infrastructure. I've got some clear ideas about how to solve these problems, principally some concepts for a new tzfile format that would let zones share representation. I'm confident of the feasibility, and I'd like to develop in this direction with a view to supplanting the present implementation, applying all due caution for stability issues. It's not necessary for me to be the TZ Coordinator in order to proceed with such a project, and I hope to do so anyway, but there's some level of convenience in the roles being colocated. In the spirit of openness, I'll now also list potential downsides of me as TZ Coordinator. Most obviously, I haven't been on the TZ mailing list very long. I tend to pick things up quickly, but this is a defect in the experience I'd bring to the role. Secondly, I have a bit of a concern that my existing role as a consumer of the TZ database (via authorship of relevant Perl modules) might compromise objectivity in developing the API (loosely speaking) that the database provides to the world. (On the other hand, it certainly provides a useful perspective.) Thirdly, I'm of the firm opinion that timezones ought to be abolished, in favour of universal use of Universal Time. Here are links to relevant resources. Other mailing lists that I'm on: http://six.pairlist.net/pipermail/leapsecs/ (leap seconds) http://www.nntp.perl.org/group/perl.datetime/ (time data in Perl) http://www.nntp.perl.org/group/perl.perl5.porters/ (Perl core) Published Perl modules: https://metacpan.org/author/ZEFRAM Video of talk about time: http://www.presentingperl.org/lpw2011/why-time-is-difficult/ Miscellaneous other bits on my web page: http://www.fysh.org/~zefram/ -zefram

Encoding of workweek/weekend available?
by Andrew Paprocki March 17, 2012

March 17, 2012

Is there any public database similar to tzdata encoding workweek/weekend transitions over time? http://en.wikipedia.org/wiki/Workweek_and_weekend I am asking the folks on this list because the transitions sound eerily like DST transitions: "The coalition government formed on December 2011 issued a decree changing the weekend in Yemen. As of February 2012 the weekend in Yemen will be Friday–Saturday [instead of Thursday–Friday]." -Andrew

Eternal DST rules for Morocco from 2012 at last
by OvV_HN March 16, 2012

March 16, 2012

From: Dan Abitbol dabitbol at streamwide.com Thu Mar 15 10:21:07 UTC 2012 Hello Sorry to disturb again but as you know Morocco have new DST rules and first change is scheduled on 25 March 15, 2012-03-15 Do you plan to release 2012c that takes into account these new rules for Morocco soon ? .............. Reply: This is not going to be easy. If I understand the rules correctly, then the clocks will be put back during the month of Ramadan. Since the Islamic calendar wanders through the Gregorian calendar, in some years the full month of Ramadan falls in the summertime period, in some years Ramadan falls in the wintertime period and in other years the month of Ramadan partially overlaps with the DST period. I made a table for a couple of forthcoming years. Please note that this table is useless! The beginning of an Islamic month starts as soon as a religious authority declares that the crescent of the moon, immediately after an astronomical new moon, has been observed. This can't be predicted, but it can be approximated by some algorithm. For the table I have used the algorithm for the arithmetical Islamic calendar from Reingold in Calendrical Calculations 2. Note that an Islamic day actually starts at sunset of the day before the day mentioned. Table. (Best viewed with a monospace font). Column 1: Islamic year count. Column 2: the last Sunday of March in the Gregorian calendar. Column 3: the last Sunday of September in the Gregorian calendar. Column 4: the first day of the islamic month Ramadan in the Gregorian calendar. Column 5: the last day of the islamic month Ramadan in the Gregorian calendar. Islamic last Sun. last Sun. first of last of year March Sept. Ramadan Ramadan Gregorian Gregorian 1433 2012-3-25 2012-9-30 2012-7-20 2012-8-18 1434 2013-3-31 2013-9-29 2013-7-9 2013-8-7 1435 2014-3-30 2014-9-28 2014-6-29 2014-7-28 1436 2015-3-29 2015-9-27 2015-6-18 2015-7-17 1437 2016-3-27 2016-9-25 2016-6-7 2016-7-6 1438 2017-3-26 2017-9-24 2017-5-27 2017-6-25 1439 2018-3-25 2018-9-30 2018-5-16 2018-6-14 1440 2019-3-31 2019-9-29 2019-5-6 2019-6-4 1441 2020-3-29 2020-9-27 2020-4-24 2020-5-23 1442 2021-3-28 2021-9-26 2021-4-13 2021-5-12 1443 2022-3-27 2022-9-25 2022-4-3 2022-5-2 1444 2023-3-26 2023-9-24 2023-3-23 2023-4-21 1445 2024-3-31 2024-9-29 2024-3-11 2024-4-9 1446 2025-3-30 2025-9-28 2025-3-1 2025-3-30 1447 2026-3-29 2026-9-27 2026-2-18 2026-3-19 1448 2027-3-28 2027-9-26 2027-2-8 2027-3-9 1449 2028-3-26 2028-9-24 2028-1-28 2028-2-26 1450 2029-3-25 2029-9-30 2029-1-16 2029-2-14 1451 2030-3-31 2030-9-29 2030-1-6 2030-2-4 1452 2031-3-30 2031-9-28 2030-12-26 2031-1-24 1453 2032-3-28 2032-9-26 2031-12-15 2032-1-13 >From the table you can see that, for instance, in the Gregorian year 2012 the month Ramadan completely falls in the summertime period. In the Gregorian year 2026 the full month Ramadan falls outside the summertime period. In the Gregorian year 2023 Moroccan summertime starts effectively April 21 plus one (this is 1 Shawwal) (give or take 2 days; see above why), since Ramadan started just before the last Sunday of March. That's my interpretation, which can differ from the official one! Oscar van Vlijmen

Turkey may go on DST permanently
