source file correction for tzdata (egypt end of daylight savings)
by John Martin Aug. 22, 2009

Aug. 22, 2009

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.

Aug. 13, 2009

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. However, time and date have August 20, 2009: http://www.timeanddate.com/worldclock/clockchange.html?n=53 We have confirmed with several properties in Cairo that DST will end on August 20th. Thanks in advance for any information. Jacquie

Where do you get time zone boundary infomation from ?
by Rod Williams Aug. 7, 2009

Aug. 7, 2009

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

Re: End of DST in Africa/Cairo 2009
by Robin Thorpe Aug. 5, 2009

Aug. 5, 2009

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.

Will Samoa observe DST?
by Gwillim Law July 30, 2009

July 30, 2009

Last November, the Cabinet of (Western) Samoa approved the adoption of DST from the first Sunday of October 2009 until the last Sunday of March 2010. Alexander Krivenyshev notified the tz list on December 7, with the subject line "Western Samoa may implement Daylight Saving Time in 2009". The tzdata file hasn't reflected any such change yet. I've just done a Web search for any further news. The only relevant articles I could find were dated last November or December. Those articles speak of the change as if it were a done deal; but some of them mention that the Attorney General's office is charged with drafting the enabling legislation. Has Samoa changed its mind and dropped the project? Is the legislation just a formality that's assured of going through? It's a little more than two months until the switch is due. I hope someone on the list is in a position to check into the situation. Gwillim Law

RE: Indiana (East) has no DST set in CLDR supplemental data
by Olson, Arthur David (NIH/NCI) [E] July 27, 2009

July 27, 2009

As Ian Davies observed, CLDR data is supplemental--not part of the time zone package. That being said... "Etc/GMT+5" would have been correct for much of Eastern Indiana through 2006 since DST wasn't observed. (Recall that there's a UNIX-heritage GMT offset sign reversal; use the commands... TZ=Etc/GMT+5 date TZ=EST date TZ=EST5 date ...to see that Etc/GMT+5 used to be the right thing.) Perhaps this particular CLDR data hasn't been updated since 2006. --ado From: Ian Davies [mailto:iand@PartyGaming.com] Sent: Monday, July 27, 2009 5:35 To: Olson, Arthur David (NIH/NCI) [E] Cc: Ian Davies Subject: Indiana (East) has no DST set in CLDR supplemental data Hi, My team has located and fixed an issue in the CLDR supplemental data for Windows TZ mapping. http://unicode.org/cldr/data/common/supplemental/supplementalData.xml Indiana (East) Mapping Changes... 1.

proposed time zone package changes
by Arthur David Olson July 14, 2009

Here are proposed time zone package changes, with summary information followed by the actual changes. If no problems are found, these will appear on the ftp site in nine days. --ado * zic.c Do not end a binary file with a POSIX-style time zone string for locations that end up in permanent DST (thanks to Andreas Schwab). * asia Arbitrarily cut off Dhaka DST at end of 2009 (so that a POSIX-style time zone string can appear in the Dhaka binary file, and for the benefit of systems with old glibc reimplementations of the time zone library that don't handle permanent DST correctly). Note that another change will be needed once the real end date for DST in Dhaka is known. * africa Change Mauritius to reflect that 2008-2009 DST experiment is not repeated (and to change end of DST in 2009 from 2:00 standard time to 2:00 local time) (thanks to Steffen Thorsen). * europe Update URL for Directive 2000/84/EC on summer-time arrangements (thanks to Colin Watson and Ian Jackson). * leapseconds Change "no leap second" comment (no leap second at end of 2009). * tz-art.htm Add notes on "A Matter of Life and Death" (thanks to Dave Cantor). * tz-link.htm Remove seemingly obsolete public.planetmirror.com/pub/timezone link (thanks to Nathan Stratton Treadway). diff -c old/africa new/africa *** old/africa Sun May 17 14:32:58 2009 --- new/africa Sat Jul 11 12:07:03 2009 *************** *** 1,5 **** # <pre> ! # @(#)africa 8.21 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)africa 8.22 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 502,512 **** # http://www.gov.mu/portal/goc/assemblysite/file/bill2708.pdf # </a> # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Mauritius 1982 only - Oct 10 0:00 1:00 S Rule Mauritius 1983 only - Mar 21 0:00 0 - !

Time zone data for Dhaka is missing an end date
by nikolaus_brauer＠us.ibm.com July 9, 2009

July 9, 2009

To whom it may concern, I am writing to report an issue I have discovered in the recent change to the Asia/Dhaka time zone data, which recently implemented daylight saving time in June. The recent update to the time zone data (tzdata2009j) includes a start date for daylight saving time, but no end date. Intuitively, daylight saving time should have a start and an end date within the same year, otherwise what is implemented is an indefinite GMT offset change. Because of this programs that detect DST rules may see the absence of an end to the DST period as an error. This may cause programs which obtain DST rules using Olson time zone data to fail to detect daylight saving time rules for Asia/Dhaka. For completeness, I propose a tentative end date be implemented now, and an updated date be implemented once an official date is released, or the government releases an additional tentative date in September. According to timeanddate.com: "The press secretary did not confirm the length of DST but stated that the government would decide the DST end date and would announce it later. On another note, Bangladesh's minister for power said earlier in 2009 that the new timing might continue until the end of September. Timeanddate.com will provide an update on the DST end date when it becomes available. " ( http://www.timeanddate.com/news/time/bangladesh-daylight-saving-2009.html ): Timeanddate.com picked September 25th, which seems like a likely enough date. I have update the tzdata on my system with the following rules to implement this change. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Dhaka09 2009 max - Jun 19 23:00 1:00 D Rule Dhaka09 2009 max - Sep 26 00:00 0:00 S # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dhaka 6:01:40 - LMT 1890 5:53:20 - HMT 1941 Oct # Howrah Mean Time? 6:30 - BURT 1942 May 15 # Burma Time 5:30 - IST 1942 Sep 6:30 - BURT 1951 Sep 30 6:00 - DACT 1971 Mar 26 # Dacca Time 6:00 Dhaka09 B%sT # Bangladesh Time Could you please evaluate this change for inclusion in the Olson time zone data? Please let me know if you have any questions or concerns. Thanks, Nik

Bangladesh DST end
by ravi-iyer.v＠nokia.com July 6, 2009

July 6, 2009

Hi there, I downloaded tzdata2009j and it does not seem to have the DST end for Bangladesh. I saw couple of threads related to this saying that the end time was still not announced by the Bangladesh government. Is that still the case? Because I can see that timeanddate.com already shows that DST ends on 25th Sep at 12:00am. If this information is correct, when can we expect to see a new version of the database? Regards, Ravi

The file... ftp://elsie.nci.nih.gov/pub/tzdata2009j.tar.gz ...is now available; this reflects the Bangladesh change circulated earlier this week on the time zone mailing list (with a short turnaround since the DST change is impending). We'll get to revisit Bangladesh once the end to DST has been set. --ado

zic produces wrong POSIX style TZ
by Andreas Schwab June 23, 2009

June 23, 2009

The current Bangladesh time zone description is unusual in that it ends with being continuously in DST. This uncovered a bug in zic, which infers a POSIX TZ string of BDST-6 from the rule. This is wrong since a time zone that is continuously in DST cannot be expressed by POSIX rules, so zic should not try to generate such a string.

Brazil considering a common time zone
by Steffen Thorsen June 20, 2009

June 20, 2009

There is a proposal to have all of Brazil follow Brasilia's time zone. The proposal received a Senate committee approval on Tuesday, June 16, 2009, it is No 486, 2008 is available in PDF (and Portuguese) here: http://legis.senado.gov.br/mate/servlet/PDFMateServlet?s=http://www.senado.… It will probably be debated, and there are no dates yet for when such a possible change will be observed from. We provide some background info about it here: http://www.timeanddate.com/news/time/brazil-one-time-zone.html Best regards, Steffen Thorsen - timeanddate.com
