by Paul Eggert May 25, 2015

May 25, 2015

It's March Madness time for daylight-saving rule changes. Here's a proposed change to the tz database to keep up with the latest political development, which affects time stamps starting March 29: * Latvia and Lithuania will not observe DST, starting this year.

Chinese timezones 1970
by Jesper Norgaard Welen Sept. 14, 2008

Sept. 14, 2008

I have investigated the timezones around 1970 on the http://www.astro.com/atlas site, and here are the results. I am attaching a GIF file of the map I have built based on this information. The red borders are the modern-time administrative borders, while the green lines are the timezone borders I have determined, note that some of them are partially hidden behind the red lines. There are no big surprises. Most timezones follow modern-day administrative boundaries, with the exceptions being Xinjiang, Xizang (Tibet), Qinghai, Gansu, Nei Mongol (Inner Mongolia) and Guangdong. There was an exception in Heliongjiang region on GMT+8.5 where the northern-most county Mohe is on GMT+8. A few other exceptions were two counties on the Sichuan side of the Xizang - Sichuan border, counties Dege and Baiyu which lies on the Sichuan side and are therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege county is GMT+8 according to astro.com while Baiyu county is GMT+6 (could be true), for the moment I am assuming that those two counties are mistakes in the astro.com data. The biggest surprise was that region Guangdong were dived in 3 timezones, a south/west part on GMT+6 (counties Xuwen, Haikang, Suixi, Lianjiang, Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, Xinyi) a central part on GMT+7 (counties Yangchun, Yangjiang, Taishan, Kaiping, Xinxing, Luoding, Yu'nan, Yunfu, Taishan, Deqing and Enping) and a north/east part on GMT+8 with the rest of the counties. Zone Asia/Harbin on GMT+8.5: regions Heilongjiang (minus Mohe) and Jilin. Zone Asia/Shanghai on GMT+8: regions east Nei Mongol, Liaoning, Hebei + Beijing, Shanxi, Shandong, Henan, Jiangsu, Anhui, Shanghai, Zhejiang, Hubei, Hunan, Jiangxi, Fujian, north/east Guangdong and Mohe county of Heilongjiang. Zone Asia/Chongqing on GMT+7: regions west Nei Mongol, Ningxia, Shaanxi, east Gansu, west Qinghai, Sichuan, Guizhou, Guangxi, Yunnan, Hainan island and the central part of Guangdong province. Zone Asia/Urumqi on GMT+6: regions east Xinjiang, west Gansu (counties Dunhuang, Aksay, Anxi, Subei), west Qinghai, east Xizang (Tibet) and east Guangdong. Zone Asia/Kashgar on GMT+5: regions west Xinjiang, west Xizang.

FW: time in southeastern Western Australia
by Olson, Arthur David (NIH/NCI) [E] Feb. 10, 2007

Feb. 10, 2007

I'm forwarding this message from Alex Livingston who, after sending it, has subscribed to the time zone mailing list. --ado -----Original Message----- From: LIVINGSTON Alex [mailto:lial@mac.com] Sent: Thursday, December 07, 2006 11:57 PM To: tz(a)lecserver.nci.nih.gov Subject: time in southeastern Western Australia Apologies if this has already been covered. I checked the latest tzdata file and there seems to be no mention of it. I have been meaning to write this for nearly four years; it was just on four years ago that I drove along the Eyre Highway, which passes through eastern Western Australia close to the southern coast of the continent. I paid particular attention to the time kept there. There can be no dispute that UTC+08:45 was considered "the time" from the border village just inside the border with South Australia to as far west as just east of Caiguna. There can also be no dispute that Eucla is the largest population centre in this zone, having a population of "40 or 50" (from memory what the proprietor of the roadhouse said when I asked him); it even has named side streets off the highway, and a very modern meteorological observatory and office. The other settlements, Cocklebiddy, Madura, Mundrabilla, and the border village, have much smaller permanent populations (around a dozen at most). So if a new zone were to be added to the tz database it should be called "Australia/Eucla". To back up my assertions I was going to refer to photographs I took of the three clocks at the border crossing (showing, Perth, local, and Adelaide time, respectively) and of the clearly "official" sign (galvanised-steel posts and frame, well-cut rectangular sheet-metal plate with rounded corners, stencilled lettering, and reflective paint) proclaiming "Central Western Time" that is seen just after leaving Caiguna heading east, but I have not published them yet and I do not have the time to check them now. (I think the sign also says, in smaller lettering, "Advance Clocks 45 Minutes".) This zone is also shown on the excellent map at http://en.wikipedia.org/wiki/Image:Timezones_optimized.png (obviously based on the CIA time-zone map). "Central Western Time" is mentioned in http://en.wikipedia.org/wiki/Time_zone, where an estimated population for this region of 200 (according with what I would have guessed) is also given. (Unfortunately the phrase "Western Central Standard Time" is used in http://en.wikipedia.org/wiki/Time_in_Australia to refer to the same thing.) Now that Western Australia is observing daylight saving, the question arose whether this part of the state would follow suit. I just called the border village [+61 (0)8 9039-3474; from online white pages] and confirmed that indeed they have, meaning that they are now observing UTC+09:45. There is one more curiosity to report about this isolated part of the world. The old Eyre telegraph station, just behind the coastal sand dunes southeast of Cocklebiddy, is now run as a bird observatory as well as a weather station and guest house. Its permanent population is 2 (a caretaker couple). I stayed there for a night on my way through and noticed that they kept a time different both from Perth and "the highway" (phrase used by caretaker; see below); they have a clock in their kitchen with a Dymo label on it stating "Eyre Std. Time" (I took a picture). It was UT+09:00, meaning a whole hour ahead of Perth, making their checking and reporting of weather data (which the Perth weather bureau expects to be done according to Perth time) simpler. I have just called them [+61 (0)8 9039-3450, also from online white pages], and they too have advanced their clocks with the rest of the state, putting them on UTC+10:00 and maintaining their one-hour difference from Perth. As far as I'm concerned this warrants another time zone, Australia/Eyre, despite the tiny permanent population! I seem to remember that what matters to this list is what time people actually keep, not statutory status. I hope the hour or two I've spent preparing and writing this turns out to be of some value.

Re: tzdata2006n Brazil incorrect fall-back date 2009-mar-01

It appears to me to be a problem in the ICU4C's code simpletz.cpp, not in the tz code or data itself, so you should ask whoever wrote simpletz.cpp to fix it. The tz data currently says that the fall-back transition in Brazil in 2009 is the last Sunday in February, which will be 2009-02-22, but the ICU4C (?) code apparently does not handle this case correctly. To some extent this is all academic. Judging by past experience, Brazil most likely will change the rules before 2009 rolls around, so the tz data is just guessing about the 2009 transition.

Canada (2007)
by Chris Walton Jan. 31, 2007

Jan. 31, 2007

For anybody wishing for info on new Canadian daylight saving legislation, I have been trying to keep the following page up to date: http://www3.sympatico.ca/c.walton/canada_dst.html The web page is full of links to various government news releases and legislation. All of Canada with the possible exception of Nunavut will be extending daylight saving this year to match the United States. Below is an extract of some of the more important hyperlinks from the web page listed above. City of Lloydminster The "Lloydminster Charter" which defines time for the city of Lloydminster on both sides of the Alberta/Saskatchewan border will likely not be amended prior to March 11. Regardless, the Senior Director of Corporate Affairs e-mailed me last year to say that Lloydminster would extend daylight saving to match Alberta. British Columbia News release: http://www2.news.gov.bc.ca/news_releases_2005-2009/2006AG0014-000330.htm Alberta News release: http://www.gov.ab.ca/acn/200602/193862BFE321E-A3D2-C519-F34B3EE936DA55E2.ht… Daylight Saving Amendment Act assented to March 23/2006: http://www.qp.gov.ab.ca/documents/spring/CH03_06.CFM?type=htm Saskatchewan No official announcement but most of Saskatchewan does not observe daylight saving time. The small area outside the Lloydminster city limits is governed by the Saskatchewan Time Act and will most likely follow Lloydminster even if the act is not updated. Manitoba News release: http://www.gov.mb.ca/chc/press/top/2005/11/2005-11-02-06.html Manitoba Official Time Amendment Act assented to December 8/2005: http://web2.gov.mb.ca/laws/statutes/2005/c05305e.php Ontario News release: http://www.attorneygeneral.jus.gov.on.ca/english/news/2005/20051020-dst.asp Ontario Regulation 111/06: Variation of Time in Effect filed April 12/2006: http://www.e-laws.gov.on.ca/DBLaws/Source/Regs/English/2006/R06111_e.htm Quebec News release (French): http://communiques.gouv.qc.ca/gouvqc/communiques/GPQF/Decembre2006/07/c5073… Legal Time Act assented to December 12/2006: http://www2.publicationsduquebec.gouv.qc.ca/dynamicSearch/telecharge.php?ty… New Brunswick News release: http://www.gnb.ca/cnb/news/pre/2005e1737pr.htm Act to Amend the Time Definition Act assented to June 22/2006: http://www.gnb.ca/0062/acts/BBA-2006/Chap-19.pdf Nova Scotia News release: http://www.gov.ns.ca/news/details.asp?id=20060425004 Royal Gazette with regulation 62/2006 on page 244: http://www.gov.ns.ca/just/regulations/rg2/2006/ma1206.pdf Prince Edward Island Act to Amend the Time Uniformity Act assented to May 24/2006: http://www.assembly.pe.ca/bills/pdf_chapter/62/3/chapter-41.pdf Newfoundland and Labrador News release: http://www.releases.gov.nl.ca/releases/2007/mpa/0118n03.htm Act to Amend the Standard Time Act assented to Dec 12/2006: http://www.hoa.gov.nl.ca/hoa/bills/Bill0634.htm Yukon News release: http://www.gov.yk.ca/news/2006/06-164.html O.I.C 2006/127: Daylight Saving Time ordered July 13/2006: http://www.gov.yk.ca/legislation/regs/oic2006_127.pdf Northwest Territories News release (Press "Daylight Savings Time Change" to see pop-up): http://www.exec.gov.nt.ca/currentnews/currentPR.asp?mode=archive It is not clear if legislation has actually been drafted. Nunavut No formal announcement has been made from the Nunavut Government. The premier of Nunavut claimed in August of 2005 that he did not want to touch the issue; nothing more has been heard since. It is likely Nunavut will eventually follow the rest of the country but there will certainly be confusion on March 11/2007 if no formal announcement is made. Currently the TZ database and Microsoft make assumptions that Nunavut will follow the rest of the country. If you find errors in the web page listed at the top of this e-mail or in this e-mail itself, please let me know. I may be somewhat unreachable for the next few days so forgive me I don't immediately respond to e-mail. -chris

I'm forwarding this message from Michele Teifke, who is not on the time zone mailing list. Those of you who are on the time zone mailing list should direct replies appropriately. Michele: what you've downloaded is the source code for the time zone compiler and source files; you get to run the source files through the compiler to create the binary files that actually get used by operating systems. Note that the "backward" source file is what's processed to create binary files such as "US/Central". Mailing list folks: this introduces a more general question--is there any open-to-the-public collection of time zone binary files? --ado ________________________________ From: Michele Teifke [mailto:mteifke@myrio.com] Sent: Wednesday, January 31, 2007 1:34 PM To: tz(a)lecserver.nci.nih.gov Subject: Looking for US timezone data files I downloaded the timezone data files from the link you gave on this page.
