About Turkey DST change
by Burak Sarıca March 23, 2011

March 23, 2011

Hi there, The DST for Turkey has been changed for this year because of a nationwide exam. There are many references in Turkish, but here is an explanation in English : http://www.timeanddate.com/news/time/turkey-starts-dst-2011.html And here is the cabinet decision about this (in turkish). http://www.resmigazete.gov.tr/eskiler/2011/03/20110310-27.htm So Turkey will move clocks forward one hour on March 28 at 3:00 a.m. Regards. Burak SARICA Senior Software Developer KocSistem AS Turkey. ________________________________ Bu e-posta mesaji kisiye ozel olup, gizli bilgiler iceriyor olabilir.

Irkutsk will change time zone to Krasnoyarsk time zone
by Alexander Krivenyshev March 16, 2011

March 16, 2011

According to various media sources (in Russian): http://www.irk.ru/news/20110316/time/ http://www.bratsk.ru/report/show/8416.html Irkutsk Region (Russia) has received government permission to change time zone to Krasnoyarsk time zone (UTC+8 summer time after March 27, 2011). On March 27, 2011 Irkutsk will keep its clock without change to Summer Time (DST) when most of Russia will move to DST. After March 27, 2011 time difference between Moscow (UTC+4 after March 27, 2011) and Irkutsk (UTC+8 after March 27, 2011) will be 4 hours, not 5 hours. or http://www.worldtimezone.com/dst_news/dst_news_russia27.html Alexander Krivenyshev, http://www.worldtimezone.com

I'm still waiting until Russia switches time later this month before making Russian changes (hoping that we'll then know what abbreviations will be used year-round for time in Russia). --ado

http://www.timeanddate.com/news/time/chile-extends-dst-2011.html The start of DST was moved from the end of the day 12 March to the end of the day on 2 April. I'm in Chile now and my laptop has updated the time incorrectly. I've had to switch to Buenos Aires time to get it right. Chas. Munat Frutillar, Chile

new map for peace river time zone region (BC, Canada)
by Chris Walton March 11, 2011

March 11, 2011

Anybody not interested in Canadian Time Zone maps can skip this post. For those that are interested, I have created a Google map showing a new definition for the Peace River time zone region in British Columbia. Click the following link and wait a few seconds for the map to load: http://maps.google.com/maps/ms?ie=UTF&msa=0&msid=212137821026080676505.0004… The time zone boundary in this new map extends further north then the boundary in my "Google Earth Canadian time zone map". I have not yet updated the Google Earth map; I will try and do that sooner or later. ############################################################################### And now for some more detail and discussion: The following web site claims that time zone boundary crosses HWY#97 just south of Pink Mountain. http://www.vancouverisland.com/regions/towns/?townID=3621 One of the larger roadmap publishers in Canada is in agreement; their maps show a time zone boundary passing just south of Pink Mountain. Looking at The National Atlas of Canada "Time Zone Map" it is possible to deduce that the time zone boundary passes somewhere near Pink Mountain. The scale of the map makes it difficult to determine the exact location of the line; Pink Mountain is far too small to actually appear on a National map. http://atlas.nrcan.gc.ca/site/english/maps/reference/national/timezones/map… ################################################################################ To the best of my knowledge there are no "time zone" road signs along HWY#97. If there are any such signs they would have to be covered up (or removed) during the summer tourist season. During the summer months all of BC (except the south east corner) is on UTC-7. ################################################################################ This week I decided to place some phone calls. I talked to employees and owners of bushiness in Pink Mountain, Sasquatch Crossing, and Buckinghorse River. I was quickly able to determine that all these places are on MST year round. It become obvious that the roadmaps, and the National Atlas of Canada, and the vancouverisland.com web site are all incorrect. I then sent an e-mail to the owner of an RV park in Sikanni Chief asking where the time zone boundary crosses HWY#97. I got a quick reply. The owner "presumed" the time zone boundary followed the district boundary between "Peace River Regional District" and "Northern Rockies Regional District". Wikipedia indicates that the district boundary was created in 1987 when "Fort Nelson - Laird Regional District" was split into "Peace River Regional District" and "Northern Rockies Regional District"; the boundary runs right along the 58th parallel. I phoned the motel in Prophet River which is just a few miles north of the district boundary. I had expected that the motel would operate on PST/PDT. The motel owner explained that the motel operates on MST; there were personal reasons for this! The motel owner also told me that the Prophet River IR a few miles up the highway uses PST/PDT. I was asked which direction I would be arriving from. I had to explain that I was calling from downtown Toronto and would not be staying in Prophet River for the night. ################################################################################## When making the new Google map, I made the time zone boundary follow the northern, southern, and eastern boundaries of the Peace River Regional District. For better or for worse, I ignored the use of MST by the single motel in Prophet River. The western boundary of the time zone region follows watershed boundaries formed by the Muskwa and Hart mountain ranges. Printed roadmaps and the National Atlas of Canada appear to follow a similar north-south line through these same mountains. And that's all for now. -chris

Thanks to Steffen Thorsen for the first report of the change. * zic.c Add curly brackets to squelch a gcc warning message.

Before going, I had noticed that wikipedia (http://en.wikipedia.org/wiki/Eastern_Time_Zone#North_America) mentioned that there was some debate about if the Dry Tortugas were in the Central or the Eastern time zone. While there, I went into the bookstore and asked if there was any truth to them being on Central Time. They looked at me as if this was the first they ever heard about this. In fact, it doesn't make any sense that they would be on anything other than Eastern Time as 99% of those visiting there are arriving via Key West, which is on Eastern Time. So, I went and modified the wikipedia page to remove the apparent misinformation about Dry Tortugas possibly being on Central Time. I then did a google search and came up with a couple of pages (http://keywestseaplanecharters.com/Tips-Secrets/default.asp, http://www.mendosa.com/fitnessblog/?p=6947) claiming that they are officially on Central Time, but that Eastern Time is used there. Is there any truth to Dry Tortugas being officially on Central Time? Did they used to be on Central Time in the past? Aaron

Chile - Daylight Saving Time extension in 2011
by Pablo Jiménez March 3, 2011

March 3, 2011

Hi, Due to a drought and as one of several actions to avoid a future electricity shortfall this year, Chile extends Daylight Saving Time till early April. According to media reports, this one-time change will take place on Saturday, April 2nd at 24:00 for America/Santiago and on Saturday, April 2nd at 22:00 for Pacific/Easter. At the moment, there's no official decree available, but you can check the information at: http://www.ansa.it/ansalatina/notizie/notiziari/chile/20110302165435226594.… http://af.reuters.com/article/metalsNews/idAFN0223009220110302 http://online.wsj.com/article/BT-CO-20110302-708197.html Best regards, -- Pablo Jimenez

proposed time zone package changes (Chile, Alaska, et al.)
by Arthur David Olson March 2, 2011

March 2, 2011

Below find proposed changes to the time zone package; the executive summary: * leapseconds Update notice from IERS (change to commentary only) * northamerica Replace Juneau with Juneau, Sitka, and Metlakatla. * southamerica Delay end of DST in 2011 until first Sunday in April. * tz-art.htm Add material on episode of "Outsourced." * zone.tab Replace Juneau with Juneau, Sitka, and Metlakatla. These change do affect current time stamps in Metlakatla and immiment time stamps in Chile. I'm waiting on making changes to Russia until we learn whether or not their new, year-round time will be called standard time; we'll see what happens at the end of this month. Since the Chile change is being made on short notice, I'll update the ftp versions on 2011-03-07 if no problems are found. --ado diff -r -c old/leapseconds new/leapseconds *** old/leapseconds Thu Dec 16 12:24:20 2010 --- new/leapseconds Mon Feb 14 09:30:33 2011 *************** *** 1,5 **** # <pre> ! # @(#)leapseconds 8.10 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)leapseconds 8.11 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 56,68 **** # SERVICE DE LA ROTATION TERRESTRE # OBSERVATOIRE DE PARIS # 61, Av. de l'Observatoire 75014 PARIS (France) ! # Tel. : 33 (0) 1 40 51 22 26 # FAX : 33 (0) 1 40 51 22 91 # Internet : services.iers(a)obspm.fr # ! # Paris, 14 July 2010 # ! # Bulletin C 40 # # To authorities responsible # for the measurement and --- 56,68 ---- # SERVICE DE LA ROTATION TERRESTRE # OBSERVATOIRE DE PARIS # 61, Av. de l'Observatoire 75014 PARIS (France) ! # Tel. : 33 (0) 1 40 51 22 29 # FAX : 33 (0) 1 40 51 22 91 # Internet : services.iers(a)obspm.fr # ! # Paris, 2 February 2011 # ! # Bulletin C 41 # # To authorities responsible # for the measurement and *************** *** 70,78 **** # # INFORMATION ON UTC - TAI # ! # NO positive leap second will be introduced at the end of December 2010. # The difference between Coordinated Universal Time UTC and the ! # International Atomic Time TAI is : # # from 2009 January 1, 0h UTC, until further notice : UTC-TAI = -34 s # --- 70,78 ---- # # INFORMATION ON UTC - TAI # ! # NO positive leap second will be introduced at the end of June 2011. # The difference between Coordinated Universal Time UTC and the ! # International Atomic Time TAI is : # # from 2009 January 1, 0h UTC, until further notice : UTC-TAI = -34 s # *************** *** 82,87 **** # will be no time step at the next possible date. # # Daniel GAMBIS ! # Director ! # Earth Orientation Center of IERS # Observatoire de Paris, France --- 82,87 ---- # will be no time step at the next possible date. # # Daniel GAMBIS ! # Head ! # Earth Orientation Center of the IERS # Observatoire de Paris, France diff -r -c old/northamerica new/northamerica *** old/northamerica Wed Jan 26 17:13:48 2011 --- new/northamerica Wed Feb 9 14:00:33 2011 *************** *** 1,5 **** # <pre> ! # @(#)northamerica 8.40 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)northamerica 8.41 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 426,431 **** --- 426,473 ---- # were nearby inhabitants in some cases and for our purposes perhaps # it's best to simply use the official transition. # + + # From Steve Ferguson (2011-01-31): + # The author lives in Alaska and many of the references listed are only + # available to Alaskan residents. + # + # <a href="http://www.alaskahistoricalsociety.org/index.cfm?section=discover%20alaska&…"> + # http://www.alaskahistoricalsociety.org/index.cfm?section=discover%20alaska&… + # </a> + + # From Arthur David Olson (2011-02-01): + # 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.

Turkish dispute over date of daylight saving time change http://www.worldbulletin.net/?aType=haber&ArticleID=69929 "Turkey plans to switch to daylight saving time on March 27 at 3 a.m., moving clocks forward one hour to make better use of daylight, but Turkish educators object to the plan because 1.5 million students will take a nationwide exam on that day."
