Re: FW: Turkey: Timezone change date delayed for one day

proposed time zone package changes (Cuba, Samoa, et al.)
by Arthur David Olson March 9, 2011

March 9, 2011

Below are proposed changes to the time zone package; here's a summary: * australasia Change end of DST in Samoa in 2011. Thanks to Raymond Hughes for information on the change. * etcetera Remove obsolete material on angle brackets in TZ envirnoment variable. * northamerica Change start of DST in Cuba in 2011. Thanks to Steffen Thorsen for the first report of the change. * zic.c Add curly brackets to squelch a gcc warning message. Since imminent time stamps in Cuba and Samoa are affected, we'll do the short turnaround dance; expect these changes on the ftp site on 2011-03-14 unless problems are found. --ado diff -r -c old/australasia new/australasia *** old/australasia Wed Jan 12 11:03:44 2011 --- new/australasia Wed Mar 9 14:38:29 2011 *************** *** 1,5 **** # <pre> ! # @(#)australasia 8.22 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)australasia 8.23 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 509,519 **** # to 01:00am and First Sunday April 2011 (03/04/11) - adjust clocks # backwards from 1:00am to 12:00am" Zone Pacific/Apia 12:33:04 - LMT 1879 Jul 5 -11:26:56 - LMT 1911 -11:30 - SAMT 1950 # Samoa Time -11:00 - WST 2010 Sep 26 ! -11:00 1:00 WSDT 2011 Apr 3 1:00 -11:00 - WST # Solomon Is --- 509,539 ---- # to 01:00am and First Sunday April 2011 (03/04/11) - adjust clocks # backwards from 1:00am to 12:00am" + # From Raymond Hughes (2011-03-07) + # I believe this will be posted shortly on the website + # <a href="http://www.mcil.gov.ws"> + # www.mcil.gov.ws + # </a> + # + # PUBLIC NOTICE ON DAYLIGHT SAVING TIME + # + # Pursuant to the Daylight Saving Act 2009 and Cabinets decision, + # businesses and the general public are hereby advised that daylight + # saving time is on the first Saturday of April 2011 (02/04/11). + # + # The public is therefore advised that when the standard time strikes + # the hour of four oclock (4.00am or 0400 Hours) on the 2nd April 2011, + # then all instruments used to measure standard time are to be + # adjusted/changed to three oclock (3:00am or 0300Hrs). + # + # Margaret Fruean ACTING CHIEF EXECUTIVE OFFICER MINISTRY OF COMMERCE, + # INDUSTRY AND LABOUR 28th February 2011 + Zone Pacific/Apia 12:33:04 - LMT 1879 Jul 5 -11:26:56 - LMT 1911 -11:30 - SAMT 1950 # Samoa Time -11:00 - WST 2010 Sep 26 ! -11:00 1:00 WSDT 2011 Apr 2 4:00 -11:00 - WST # Solomon Is diff -r -c old/etcetera new/etcetera *** old/etcetera Thu Dec 16 12:24:20 2010 --- new/etcetera Wed Mar 9 14:27:36 2011 *************** *** 1,5 **** # <pre> ! # @(#)etcetera 8.2 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)etcetera 8.3 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 36,43 **** # (i.e. west of Greenwich) even though many people would expect it to # mean 4 hours ahead of UTC (i.e. east of Greenwich). # ! # In the draft 5 of POSIX 1003.1-200x, the angle bracket notation ! # (which is not yet supported by the tz code) allows for # TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to # ISO 8601 you can use TZ='<-0400>+4'.

Dry Tortugas is Central or Eastern Time?
by Aaron Brown March 4, 2011

March 4, 2011

I just went to Dry Tortugas National Park last weekend, about 70 miles west of Key West. 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
