Petr Machata (2011-03-30):
They have it written in English here: http://www.map.ma/eng/sections/home/morocco_to_spring_fo/view It says there that "Morocco will resume its standard time on July 31, 2011 at midnight." Now they don't say whether they mean midnight of wall clock time (i.e. 11pm UTC), but that's what I would assume. It has also been like that in the past.
Arthur David Olson (2011-06-15):
While Russia abandoned DST in 2011, Armenia may choose to follow Russia's "old" rules.
Steffen Thorsen (2011-08-26):
Gaza and the West Bank did go back to standard time in the beginning of August, and will now enter daylight saving time again on 2011-08-30 00:00 (so two periods of DST in 2011). The pause was because of Ramadan. http://www.maannews.net/eng/ViewDetails.aspx?ID=416217 Additional info: https://www.timeanddate.com/news/time/palestine-dst-2011.html
Alexander Krivenyshev (2011-08-27):
According to the article in The Jerusalem Post: "...Earlier this month, the Palestinian government in the West Bank decided to move to standard time for 30 days, during Ramadan. The Palestinians in the Gaza Strip accepted the change and also moved their clocks one hour back. The Hamas government said on Saturday that it won't observe summertime after the Muslim feast of Id al-Fitr, which begins on Tuesday..." ... https://www.jpost.com/MiddleEast/Article.aspx?id=235650 http://www.worldtimezone.com/dst_news/dst_news_gazastrip05.html The rules for Egypt are stolen from the 'africa' file.
Steffen Thorsen (2011-09-30):
West Bank did end Daylight Saving Time this morning/midnight (2011-09-30 00:00). So West Bank and Gaza now have the same time again. Many sources, including: http://www.maannews.net/eng/ViewDetails.aspx?ID=424808
Steffen Thorsen (2011-10-03):
Now the dates have been confirmed, and at least our start date assumption was correct (end date was one week wrong). http://www.fiji.gov.fj/index.php?option=com_content&view=article&id=4966:daylight-saving-starts-in-fiji&catid=71:press-releases&Itemid=155 which says Members of the public are reminded to change their time to one hour in advance at 2am to 3am on October 23, 2011 and one hour back at 3am to 2am on February 26 next year. From Ken Rylander (2011-10-24) Another change to the Fiji DST end date. In the TZ database the end date for Fiji DST 2012, is currently Feb 26. This has been changed to Jan 22. http://www.fiji.gov.fj/index.php?option=com_content&view=article&id=5017:amendments-to-daylight-savings&catid=71:press-releases&Itemid=155 states: The end of daylight saving scheduled initially for the 26th of February 2012 has been brought forward to the 22nd of January 2012. The commencement of daylight saving will remain unchanged and start on the 23rd of October, 2011. From the Fiji Government Online Portal (2012-08-21) via Steffen Thorsen: The Minister for Labour, Industrial Relations and Employment Mr Jone Usamate today confirmed that Fiji will start daylight savings at 2 am on Sunday 21st October 2012 and end at 3 am on Sunday 20th January 2013. http://www.fiji.gov.fj/index.php?option=com_content&view=article&id=6702&catid=71&Itemid=155 From the Fijian Government Media Center (2013-08-30) via David Wheeler: Fiji will start daylight savings on Sunday 27th October, 2013 ... move clocks forward by one hour from 2am http://www.fiji.gov.fj/Media-Center/Press-Releases/DAYLIGHT-SAVING-STARTS-ON-SUNDAY,-27th-OCTOBER-201.aspx

Arthur David Olson (2011-06-15):
Take "abolishing daylight saving time" to mean that time is now considered to be standard. Previous editions of this database used abbreviations like MET DST for Central European Summer Time, but this didn't agree with common usage.
Yauhen Kharuzhy (2011-09-16):
By latest Belarus government act Europe/Minsk timezone was changed to GMT+3 without DST (was GMT+2 with DST).

Alexander Krivenyshev (2011-10-17):
Pridnestrovian Moldavian Republic (PMR, also known as "Pridnestrovie") has abolished seasonal clock change (no transition to the Winter Time). News (in Russian): http://www.kyivpost.ua/russia/news/pridnestrove-otkazalos-ot-perehoda-na-zimnee-vremya-30954.html http://www.allmoldova.com/moldova-news/1249064116.html The substance of this change (reinstatement of the Tiraspol entry) is from a patch from Petr Machata (2011-10-17) From Tim Parenti (2011-10-19) In addition, being situated at +4651+2938 would give Tiraspol a pre-1880 LMT offset of 1:58:32. (which agrees with the earlier entry that had been removed) From Alexander Krivenyshev (2011-10-26) NO need to divide Moldova into two timezones at this point. As of today, Transnistria (Pridnestrovie)- Tiraspol reversed its own decision to abolish DST this winter. Following Moldova and neighboring Ukraine- Transnistria (Pridnestrovie)- Tiraspol will go back to winter time on October 30, 2011.

Büsingen <http://www.buesingen.de>, surrounded by the Swiss canton Schaffhausen, did not start observing DST in 1980 as the rest of DE (West Germany at that time) and DD (East Germany at that time) did. DD merged into DE, the area is currently covered by code DE in ISO 3166-1, which in turn is covered by the zone Europe/Berlin.

...it appears that Mercer County, North Dakota, changed from the mountain time zone to the central time zone at the last transition from daylight-saving to standard time (on Nov. 7, 2010): https://www.gpo.gov/fdsys/pkg/FR-2010-09-29/html/2010-24376.htm http://www.bismarcktribune.com/news/local/article_1eb1b588-c758-11df-b472-001cc4c03286.html

...according to the Census Bureau, the largest city is Beulah (although it's commonly referred to as Beulah-Hazen, with Hazen being the next largest city in Mercer County). Google Maps places Beulah's city hall at 47° 15' 51" N, 101° 46' 40" W, which yields an offset of 6h47'07".

Here's database-relevant material from the 2001 "Alaska History" article: On September 20 [1979]...DOT...officials decreed that on April 27, 1980, Juneau and other nearby communities would move to Yukon Time. Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on Pacific Time. ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the Department's September 1979 decision. Juneau and other communities in northern Southeast reverted to Pacific Time on October 26. On October 28 [1983]...the Metlakatla Indian Community Council voted unanimously to keep the reservation on Pacific Time. According to DOT official Joanne Petrie, Indian reservations are not bound to follow time zones imposed by neighboring jurisdictions. (The last is consistent with how the database now handles the Navajo Nation.)
Arthur David Olson (2011-02-09):
I just spoke by phone with a staff member at the Metlakatla Indian Community office (using contact information available at http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla It's shortly after 1:00 here on the east coast of the United States; the staffer said it was shortly after 10:00 there. When I asked whether that meant they were on Pacific time, they said no - they were on their own time. I asked about daylight saving; they said it wasn't used. I did not inquire about practices in the past.
Arthur David Olson (2011-08-17):
For lack of better information, assume that Metlakatla's abandonment of use of daylight saving resulted from the 1983 vote.

The following is from "Laws of the Territory of Hawaii Passed by the Seventeenth Legislature: Regular Session 1933," available (as of 2011-01-19) at American University's Pence Law Library. Page 85: "Act 90...At 2 o'clock ante meridian of the last Sunday in April of each year, the standard time of this Territory shall be advanced one hour...This Act shall take effect upon its approval. Approved this 26th day of April, A. D. 1933. LAWRENCE M JUDD, Governor of the Territory of Hawaii." Page 172: "Act 163...Act 90 of the Session Laws of 1933 is hereby repealed...This Act shall take effect upon its approval, upon which date the standard time of this Territory shall be restored to that existing immediately prior to the taking effect of said Act 90. Approved this 21st day of May, A. D. 1933. LAWRENCE M. JUDD, Governor of the Territory of Hawaii." Note that 1933-05-21 was a Sunday. We're left to guess the time of day when Act 163 was approved; guess noon. Zone NAME STDOFF RULES FORMAT [UNTIL]

Back in 2007 I initiated the creation of a new "zone file" for Resolute Bay. Resolute Bay is a small community located about 900km north of the Arctic Circle. The zone file was required because Resolute Bay had decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007. According to new information which I received last week, Resolute Bay went back to using UTC-6 in the winter of 2007-2008... On March 11/2007 most of Canada went onto daylight saving. On March 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I talked to somebody that was both knowledgeable and helpful. I was able to confirm that Resolute Bay was still operating on UTC-5. It was explained to me that Resolute Bay had been on the Eastern Time zone (EST) in the winter, and was now back on the Central Time zone (CDT). i.e. the time zone had changed twice in the last year but the clocks had not moved. The residents had to know which time zone they were in so they could follow the correct TV schedule... On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I phoned the Resolute Bay hamlet office...[D]ue to the challenging nature of the phone call, I decided to seek out an alternate source of information. I found an e-mail address for somebody by the name of Stephanie Adams whose job was listed as "Inns North Support Officer for Arctic Co-operatives." I was under the impression that Stephanie lived and worked in Resolute Bay... On March 14/2011 I phoned the hamlet office again. I was told that Resolute Bay had been using Central Standard Time over the winter of 2010-2011 and that the clocks had therefore been moved one hour ahead on March 13/2011. The person I talked to was aware that Resolute Bay had previously experimented with Eastern Standard Time but he could not tell me when the practice had stopped. On March 17/2011 I searched the Web to find an e-mail address of somebody that might be able to tell me exactly when Resolute Bay went off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz used to be the mayor of Resolute Bay and he apparently owns half the businesses including "South Camp Inn." This website has some info on Aziz: http://www.uphere.ca/node/493 I sent Aziz an e-mail asking when Resolute Bay had stopped using Eastern Standard Time. Aziz responded quickly with this: "hi, The time was not changed for the 1 year only, the following year, the community went back to the old way of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in the winter Zulu plus 6 hrs" This of course conflicted with everything I had ascertained in November 2008. I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You may want to check with the weather office in Resolute Bay or do a search on the weather through Env. Canada. web site" If I had realized the Stephanie did not live in Resolute Bay I would never have contacted her. I now believe that all the information I obtained in November 2008 should be ignored... I apologize for reporting incorrect information in 2008.

Chile's clocks will go back an hour this year on the 7th of May instead
of this Saturday. They will go forward again the 3rd Saturday in
August, not in October as they have since 1968. Steffen Thorsen (2011-04-01):
The Falkland Islands will not turn back clocks this winter, but stay on daylight saving time. One source: http://www.falklandnews.com/public/story.cfm?get=5914&source=3 We have gotten this confirmed by a clerk of the legislative assembly: Normally the clocks revert to Local Mean Time (UTC/GMT -4 hours) on the third Sunday of April at 0200hrs and advance to Summer Time (UTC/GMT -3 hours) on the first Sunday of September at 0200hrs. IMPORTANT NOTE: During 2011, on a trial basis, the Falkland Islands will not revert to local mean time, but clocks will remain on Summer time (UTC/GMT - 3 hours) throughout the whole of 2011. Any long term change to local time following the trial period will be notified. From Andrew Newman (2012-02-24) A letter from Justin McPhee, Chief Executive, Cable & Wireless Falkland Islands (dated 2012-02-22) states... The current Atlantic/Stanley entry under South America expects the clocks to go back to standard Falklands Time (FKT) on the 15th April. The database entry states that in 2011 Stanley was staying on fixed summer time on a trial basis only. FIG need to contact IANA and/or the maintainers of the database to inform them we're adopting the same policy this year and suggest recommendations for future years. For now we will assume permanent -03 for the Falklands until advised differently (to apply for 2012 and beyond, after the 2011 experiment was apparently successful.)

Chris Walton (2011-12-01):
There are two areas within the Canadian province of British Columbia that do not currently observe daylight saving: a) The Creston Valley (includes the town of Creston and surrounding area) b) The eastern half of the Peace River Regional District (includes the cities of Dawson Creek and Fort St. John) Earlier this year I stumbled across a detailed article about the time keeping history of Creston; it was written by Tammy Hardwick who is the manager of the Creston & District Museum. The article was written in May 2009. http://www.ilovecreston.com/?p=articles&t=spec&ar=260 According to the article, Creston has not changed its clocks since June 1918. i.e. Creston has been stuck on UT-7 for 93 years. Dawson Creek, on the other hand, changed its clocks as recently as April 1972. Unfortunately the exact date for the time change in June 1918 remains unknown and will be difficult to ascertain. I e-mailed Tammy a few months ago to ask if Sunday June 2 was a reasonable guess. She said it was just as plausible as any other date (in June). She also said that after writing the article she had discovered another time change in 1916; this is the subject of another article which she wrote in October 2010. http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56 Here is a summary of the three clock change events in Creston's history: 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7) Exact date unknown 2. Oct 1916: switch to Pacific Standard Time (GMT-8) Exact date in October unknown; Sunday October 1 is a reasonable guess. 3. June 1918: switch to Pacific Daylight Time (GMT-7) Exact date in June unknown; Sunday June 2 is a reasonable guess. note 1: On Oct 27/1918 when daylight saving ended in the rest of Canada, Creston did not change its clocks. note 2: During WWII when the Federal Government legislated a mandatory clock change, Creston did not oblige. note 3: There is no guarantee that Creston will remain on Mountain Standard Time (UTC-7) forever. The subject was debated at least once this year by the town Council. http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html During a period WWII, summer time (Daylight saying) was mandatory in Canada. In Creston, that was handled by shifting the area to PST (-8:00) then applying summer time to cause the offset to be -7:00, the same as it had been before the change. It can be argued that the timezone abbreviation during this period should be PDT rather than MST, but that doesn't seem important enough (to anyone) to further complicate the rules. The transition dates (and times) are guesses.
