Error in time zone for Egypt
by Martin Höfler Aug. 15, 2010

Aug. 15, 2010

Hi! I think there's an error in the time zone description of Egypt for 2010: during Ramadan, Egypt switches back to standard time and at the end of Ramadan it's daylight saving time again. This is the respective rule: Rule Egypt 2010 only - Sep 9 0:00s 1:00 S However, Ramadan seems to end at midnight between the 9th and the 10th of September (it lasts 30 days, which includes the 9th). See http://www.timeanddate.com/news/time/egypt-ends-dst-2010.html So the rule should be: Rule Egypt 2010 only - Sep 9 24:00s 1:00 S Or Rule Egypt 2010 only - Sep 10 0:00s 1:00 S I'm not 100% sure about all this (I'm no expert), but as the other sources in the time zone file don't mention a specific switch time, I think the rule needs to be corrected. Best regards, Martin Hoefler

Maybe a mistake in tzdata2010k.tar.gz
by Stanley, Rick Aug. 4, 2010

Aug. 4, 2010

Hi, I got your email from http://www.twinsun.com/tz/tz-link.htm. I have recently downloaded this tz file: tzdata2010k.tar.gz I have compiled the tz file for Egypt and find the following: bash-3.00# zdump -v Egypt | grep 2010 Egypt Thu Apr 29 21:59:59 2010 UTC = Thu Apr 29 23:59:59 2010 EET isdst=0 Egypt Thu Apr 29 22:00:00 2010 UTC = Fri Apr 30 01:00:00 2010 EEST isdst=1 Egypt Tue Aug 10 20:59:59 2010 UTC = Tue Aug 10 23:59:59 2010 EEST isdst=1 Egypt Tue Aug 10 21:00:00 2010 UTC = Tue Aug 10 23:00:00 2010 EET isdst=0 Egypt Wed Sep 8 21:59:59 2010 UTC = Wed Sep 8 23:59:59 2010 EET isdst=0 Egypt Wed Sep 8 22:00:00 2010 UTC = Thu Sep 9 01:00:00 2010 EEST isdst=1 Egypt Thu Sep 30 20:59:59 2010 UTC = Thu Sep 30 23:59:59 2010 EEST isdst=1 Egypt Thu Sep 30 21:00:00 2010 UTC = Thu Sep 30 23:00:00 2010 EET isdst=0 All of this looks correct, except for the Sep 8 - Sep 9 changes. Here is what I find on the web about time changes in Egypt: DST ends<http://www.timeanddate.com/worldclock/clockchange.html?n=53> on Midnight between Tuesday, August 10, 2010 and Wednesday, August 11, 2010 local daylight time DST starts<http://www.timeanddate.com/worldclock/clockchange.html?n=53> on Midnight between Thursday, September 9, 2010 and Friday, September 10, 2010 local standard time DST ends<http://www.timeanddate.com/worldclock/clockchange.html?n=53> on Midnight between Thursday, September 30, 2010 and Friday, October 1, 2010 local daylight time On the web, DST starts between Sept 9 and 10th In the TZ file, DST starts between Sept 8 and 9th.

Australian timezone abbreviation EST
by Joachim Wieland Aug. 3, 2010

Aug. 3, 2010

Hi there, I am a bit confused by the definition of some Australian timezones in the database, maybe someone could shed some light here... When I look at Melbourne for example, I see: [...] Rule AV 2008 max - Apr Sun>=1 2:00s 0 - Rule AV 2008 max - Oct Sun>=1 2:00s 1:00 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Australia/Melbourne 9:39:52 - LMT 1895 Feb 10:00 Aus EST 1971 10:00 AV EST It looks like there is only one valid timezone abbreviation, which is EST! EST seems to change its offset whenever Australia/Melbourne changes from dst or back? Isn't that more than confusing? How would one know what time "4:15pm EST" is?! Or am I only misreading this? http://www.travelmath.com/time-zone/Australia/Melbourne tells me: "The GMT offset is currently UTC/GMT +10 hours (EST). It will change [...]. The new GMT offset will be UTC/GMT +11 hours (EST)." Thanks for your help, Joachim PS: I am not subscribed to the list, it would be nice if you could copy me in your replies. Thanks.

Re: Egypt plan to [cancel] DST during Ramadan and then to resume DST again.
by Arthur David Olson July 30, 2010

July 30, 2010

We have this at http://www.almasryalyoum.com/en/news/clocks-go-back-during-ramadan-and-then…: In a statement released yesterday, the cabinet clarified that clocks will move back by one hour at midnight on Tuesday 10 August, to be moved forward again after Ramadan, on Thursday 9 September. Clocks will roll back once more on Thursday 30 September to put the nation on winter time, as stipulated by law. Mosslem Shaltout, professor of solar-space physics and vice-chairman of the Arab Union for Astronomy and Space Sciences (AUASS), said Ramadan will start, atronomically speaking, on Wednesday 11 August. According to Shaltout, the moon's crescent will appear at 6:08 AM on 10 August, when the moon is on the same level with the sun and earth, marking the beginning of Ramadan. Mosslem Shaltout is said to refer to an August 10 crescent moon, and also is said to refer to an August 11 start of Ramadan. We also have this at http://www.timeanddate.com/news/time/egypt-ends-dst-2010.html: DST ends and clocks will move one hour back at midnight (00:00) between Tuesday August 10, and Wednesday August 11, in 2010. Egypt will revert back to DST after Ramadan and move their clocks forward at midnight (00:00) between Thursday, September 9, and Friday September 10, 2010. Egypt will end its 2010 DST schedule at midnight (00:00) local time between Thursday, September 30, and Friday, October 1. Perhaps the clearest translation to rules is: Rule Egypt 2010 only - Aug 11 0:00 0 - Rule Egypt 2010 only - Sep 10 0:00 1:00 S The first rule behaves the same way as what's now in the "africa" file; the second rule restarts DST a day later than what's now in the file. --ado
