I’m forwarding this message from John D. Martin III, who is not on the time zone mailing list. Those of you who are on the time zone mailing list, please direct replies appropriately. John's message indicates a change at the midnight between Friday, August 21 and Saturday, August 22 while the current "Africa" file indicates a change at the midnight between Thursday, August 20 and Friday, August 21. Is there anyone with boots on the ground in Egypt who can tell us what actually happened last week? --ado From: John Martin [mailto:john.d.martin.iii@gmail.com] Sent: Saturday, August 22, 2009 6:43 To: tz(a)lecserver.nci.nih.gov Subject: source file correction for tzdata (egypt end of daylight savings) I am sending some info about the end of daylight savings time for Egypt in 2009. The line for 2009 for Egypt/Cairo in 'africa' within the tzdata source should read : Rule Egypt 2009 only - Aug 21 23:00s 0 - Rule Egypt 2010 max - Sep lastThu 23:00s 0 - The beginning of Ramadan has been used to determine the switch to standard time. In 2009 the switch occurred on 21 August at midnight or the third Thursday of the month. This will likely revert in 2010 to the standard time in the last week in September. Thanks. J -- John D.

Where do you get time zone boundary infomation from ?
by Rod Williams 07 Aug '09

07 Aug '09

I am a software engineer working for an avionics company. I am currently working on a project that requires the software I will create to know the time *any place on earth given a latitude and longitude*. Time zone boundaries and time rules will need be *updated on a monthly basis*. This task is proving to be very difficult. The most difficult part is getting up to date data on for time zone boundaries. *Most of the services and databases I have researched only give time zone information for a particular city in that given time zone (ie. Olson Time Zone Database), I have yet to find anything that defines the actual time zone boundaries.* *Is there a service or database that gives up to date boundary and time rules monthly, and has worldwide coverage?* Thanks in advance, Rod Williams

Dear Jacquie, Paul is out of the office on vacation until Monday, August 10, 2009, but I can help you with your question. We are aware of the daylight savings issue in Egypt and are monitoring it closely. According to previous announcements daylight savings time should change the last weekend in September. However, this year is different due to Ramadan starting August 22. It is probable that the government will make a change, but there has been no official decision as of today. Historically the government has made the announcement about one week prior to the start of Ramadan. If they follow this pattern the announcement would come around August 15. According to our sources the last possible day for the announcement is August 20 since Ramadan begins on August 22. We will issue an update as soon as a change is announced and confirmed. I hope this addresses your concerns. If it doesn't or if you have other questions please feel free to email or call me at 212-742-8577. Kind regards, Robin At 02:44 PM 8/5/2009, jacquie(a)entropy.cc wrote: >Hi, > >Does anyone know of an update for the end of DST in Africa/Cairo? >According to the latest tzdata2009k.tar.gz, DST will end on >September 24, 2009.
