URL change OvV
by vanadovv＠hetnet.nl Jan. 30, 2014

Jan. 30, 2014

Hello! I would like to inform you that my timezone pages will move from telfort.nl to kpn.nl. Two of my pages are listed on tz-link.htm, part of the TZ distribution. (1) href="http://home.telfort.nl/~t876506/TZworld.html" Complete timezone information for all countries - displays tables of DST rules. New URL: http://home.kpn.nl/vanadovv/time/TZworld.html (2) href="http://home.telfort.nl/~t876506/Multizones.html" Time zone boundaries for multizone countries - summarizes legal boundaries between time zones within countries. New URL: http://home.kpn.nl/vanadovv/time/Multizones.html The move is in effect as of now. My web site at telfort.nl will be shut down per 01 Feb. 2014. Please change your bookmarks and references.

Europe/Pristina
by Morgan Sowden Jan. 28, 2014

Jan. 28, 2014

Hi There, Apologies if this issue has already been raised, but I couldn't find any references in the mailing list's archives. We run a high traffic website and have just updated it so that we can send out emails at the time set by the user. We thus implemented PyTZ as we have users from all over the world. We included Kosovo as a country in our country list (requested by some users) but there is no matching timezone for it in the DB. We're assuming that the convention would dictate the one should add "Europe/Pristina" (the capital) and then it could use the same rules as for "Europe/Belgrade" or "Europe/Tirana" regarding the setting of time. There is no official ISO code for Kosovo yet, though KS seems to be evolving as a standard. Feedback welcome. Kind Regards

Correct Time in the Hashemite Kingdom of Jordan
by Keith Jones Jan. 27, 2014

Jan. 27, 2014

To Whom It May Concern, If you have the authority to make changes to the time zone database or know who does have the authority, please be informed that Jordan's time is now the same as Eastern European Standard Time. The government of Jordan decided this year (last year, too) to not follow Daylight Savings Time, but then after much pressure from many sides and some unfortunate events decided to change time (this happened December 19/20). Unfortunately, computers and devices relying on automatic times and zones have yet to make this adjustment. If you could help correct this, certainly hundreds of thousands and probably millions would be very grateful. Thank you! Keith Jones Amman, Jordan PS - Strange thing... an older IPhone 3GS running 6.1.3 (10B329) gets the time right, but our iPhone 5's and iPads running iOS 7.?? are off and hour. Strange.

Non-valid timezones, is there a rule to remove them?
by Fabiano Fidêncio Jan. 24, 2014

Jan. 24, 2014

Howdy! Looking at the zone.tab file I can see a few timezones that, although valid in the past, they are not valid anymore. I can pick as example, reported on the GNOME Bugzilla[0], Asia/Novosibirsk, that used to be UTC+7, but nowadays is considered the same one than Asia/Almaty, which one is UTC+6. How is the rule about keep or remove these not-used-anymore timezones? Would you guys accept a patch removing the not-used-anymore ones? What kind of information should I provide/get to be sure that one timezone could be removed? Thanks is advance and Best Regards.

excellent Sources for Time Zone and Daylight Saving Time Data page, thanks
by Tracy Haynes Jan. 23, 2014

Jan. 23, 2014

Hi there! I wanted to thank you for your page http://www.iana.com/time-zones/repository/tz-link.html It's been really useful as I've been putting together a collection of resources for my boss to use and refer to in his own writing; I hope you don't mind my using your page! He actually just wrote an article about time zones that you might enjoy: "Understanding Time Zones" http://www.wakanow.com/ng/pages/Understanding-Time-Zones Would you mind adding my article to your page with all your other other helpful resources? I think showing my boss that I'm making connections and reaching out would go a long way in giving me an edge in my new position:) Thank you so much, and let me know what you think!

Newly proposed 10 time zones in Russia - draft Federal Law 431985-6
by Alexander Krivenyshev Jan. 23, 2014

Jan. 23, 2014

Below is information concerning a DRAFT amendment (Russian Federal Law N 431985-6) "On the calculation of time" which was recently introduced to Russian State Duma on January 20, 2014. Original Draft Federal Law document as PDF at the Russian State Duma web site: (in Russian) http://asozd2.duma.gov.ru/main.nsf/%28SpravkaNew%29?OpenAgent&RN=431985-6&02 or our link (in Russian) at http://www.worldtimezone.com/dst_news/dst_news_russia59.html An English translation of the newly proposed 10 time zones in Russia and corresponding areas/cities/administrative centers in the Russian Federation defined in the table (translated and compiled by WorldTimeZone) at link: http://www.worldtimezone.com/dst_news/dst_news_russia60.html The new proposal 431985-6 suggests moving the clock back one (1) hour for almost all regions (including Moscow). In some regions (Chita, Vladivostok, Khabarovsk, Sakha-Yakutia, Omsk, Birobidzhan, Orenburg, Perm, Ufa) the suggestion to turn clocks by two (2) hours back (-2 hours) would therefore force those regions to potentially change their time zones. If approved, the new bill would take effect on October 26, 2014. Alexander Krivenyshev http://www.WorldTimeZone.com

Paraguay 2014 discrepancy
by Andrew Paprocki Jan. 22, 2014

Jan. 22, 2014

When Paraguay decided to move DST back to March in 2013, it appears that the database records this as 2013->max (i.e., permanent) but timeanddate.comrecorded it as only applying to 2013. The page for Asuncion (http://www.timeanddate.com/worldclock/city.html?n=21) currently shows a DST date of 12 April, 2014. Is the database correct or is timeanddate.com correct? I fully expect governments to flip-flop, but there should probably be a consistent date until an official law is passed. -Andrew

New proposal to return Russia 10 time zones and adjust regions to the standard time
by Alexander Krivenyshev Jan. 20, 2014

Jan. 20, 2014

New bill on changing time in Russia was submitted today (January 20, 2014). New bill will be more complicated than a simple change clocks back to the winter time. The proposals included: - to change Moscow time zone to UTC+3 from current UTC+4. - return Russia 10 time zones (today Russia uses nine time zones). - adjust each region to its standard time zone. - no seasonal time change (no DST). If approved, the new bill will go into effect on October 26, 2014. ITAR-TASS Novosti (in Russian) http://itar-tass.com/obschestvo/897800 Alexander Krivenyshev - WorldTimeZone.com

[PATCH] Simplify some ALL_STATE and PCTS ifdefs.
by Paul Eggert Jan. 18, 2014

Jan. 18, 2014

* Makefile (GCC_DEBUG_FLAGS): Add -Wno-address and -Wno-cast-qual. Otherwise, GCC 4.8.1 complains about some of the following changes. * localtime.c (wildabbr): Now const. This is a tiny bit more efficient, POSIX allows it, and the ALL_STATE simplifications below make use of it. All uses changed to cast if needed. (settzname, tzload, localsub, gmtsub, timesub, time2sub, time1): Protect less code with ALL_STATE; this is simpler and doesn't change behavior (or, these days, efficiency).

Timezones in Jordan
by Michael Gardiner Jan. 3, 2014

Jan. 3, 2014

Can you explain the current situation with regards to timezone data for Jordan. I work in the Australian Embassy in amman Jordan and am having a lot of issues with setting the correct time. On our computers when we use a NTP source such as: server 0.pool.ntp.org 120.88.46.10 server 1.pool.ntp.org server 2.pool.ntp.org server 3.pool.ntp.org It sets the clock 1 hour ahead of the correct time so I have to set them all manually which is not good. I have had a look at TZDATA2013i and it had the time as UTC +2 which should give us the correct time. Any Advise would be great. Regards Michael Gardiner First Secretary Technical Australian Embassy Amman Screen shot of using NTP server advances time by 1 hour: Having to Manually set the time (+4 minutes is writing the email): --

India might get a second time zone
by Steffen Thorsen Jan. 2, 2014

Jan. 2, 2014

India might get a second time zone, the Government of Assam wants to move 1 hour ahead of the rest of India. So that will be a time zone of UTC+6:30 in that case. Date for the change is not yet announced, and it might need approval from central government, but from the news sources it sounds like it is quite likely to happen.

[PATCH] Initialize sp->defaulttype in tzparse()
by Logan Chien Jan. 2, 2014

Jan. 2, 2014

Hi, I found that sometimes the localtime() won't work properly, if sp->defaulttype is not set properly. For example, given the following code: time_t epoch = 0; setenv("TZ", "UTC+00", 1); tzset(); printf("%s", ctime(&epoch)); // (a) setenv("TZ", "Asia/Taipei", 1); tzset(); printf("%s", ctime(&epoch)); // (b) setenv("TZ", "UTC+00", 1); tzset(); printf("%s", ctime(&epoch)); // (c) The expected output should be: Thu Jan 1 00:00:00 1970 Thu Jan 1 08:00:00 1970 Thu Jan 1 00:00:00 1970 However, the output is: Thu Jan 1 00:00:00 1970 Thu Jan 1 08:00:00 1970 Thu Jan 1 08:00:00 1970 This is due to the fact that sp->defaulttype is set to 1 when we are using "Asia/Taipei" as the timezone, but it is not reset after we change the timezone to "UTC+00". As the result, the old value in sp->types[sp->defaulttype] is incorrectly used. The attached patch should resolve this issue. Please have a look. Thanks. Sincerely, Logan

Fwd: Future of Time at DC AAS meeting
by David Patte ₯ Dec. 20, 2013

Dec. 20, 2013

Forwarded from the International Sundial List, that I am also on... The announcement for a AAS splinter meeting on the leap second / UTC issue is appended. We welcome the participation of members of the sundial community who will be attending the American Astronomical Society meeting or those who may be located near Washington, DC. AAS registration is not required to participate. Please forward the announcement to anybody you think might be interested in the future of solar time. Rob Seaman NOAO -- Dear Colleague, This is an announcement of a splinter meeting to be held at the upcoming 223rd Meeting of the American Astronomical Society at the Gaylord National Resort near Washington, DC: The Future of Time Sunday, 5 January 2014 1:00 pm - 5:00 pm National Harbor 6 (note room change) Time is a very broad subject and contacts are being made among distant corners of the AAS community, including history and E/PO, observatory operations, software and systems, and in various fields of research. The topic is a proposal being vigorously pursued within the International Telecommunication Union, an agency of the United Nations, that would redefine Coordinated Universal TIme (the time on your alarm clock, wristwatch, computer and smartphone) to no longer be tied to the rotation of the Earth. We will discuss the historical context for this unprecedented proposal, as well as its significant implications for the practice of astronomy. More details are on the web page (w/ links to preprints from two previous meetings in 2011 and 2013): http://www.cacr.caltech.edu/futureofutc/aas223/ To maximize flexibility for attendees, the Future of Time agenda is split into two 2 hour sessions (below). Your participation will be welcome at either or both sessions. Rob Seaman, NOAO Ken Seidelmann, U. Virginia Arnold Rots, SAO Alison Peck, NRAO -- Session 1 - The Future of Time I historical context (1:00 pm) Introduction A (brief) history of time in astronomy (K.

[tz-announce] 2013i release of tz code and data available
by Paul Eggert Dec. 19, 2013

Dec. 19, 2013

The 2013i release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Changes affecting near-future time stamps: Jordan switches back to standard time at 00:00 on December 20, 2013. The 2006-2011 transition schedule is planned to resume in 2014. (Thanks to Steffen Thorsen.) Changes affecting past time stamps: In 2004, Cuba began DST on March 28, not April 4. (Thanks to Steffen Thorsen.) Changes affecting code The compile-time flag NOSOLAR has been removed, as nowadays the benefit of slightly shrinking runtime table size is outweighed by the cost of disallowing potential future updates that exceed old limits. Changes affecting documentation and commentary The files solar87, solar88, and solar89 are no longer distributed. They were a negative experiment -- that is, a demonstration that tz data can represent solar time only with some difficulty and error. Their presence in the distribution caused confusion, as Riyadh civil time was generally not solar time in those years. tz-link.htm now mentions Noda Time. (Thanks to Matt Johnson.)
