The zone.tab comment for Antarctica/Vostok

Inconsistency in zoneinfo binary files?
by Roland Bock Aug. 16, 2010

Aug. 16, 2010

Hi, I hope that this is the right list to ask this question: I am having trouble in comprehending the zoneinfo binary files: I have a version 2 file for Amsterdam which gives me 180 transition times and 13 transition types in the first block (all of which look fine to me). But the second block yields 181 transition times and 14 transition types. The additional transition time is 1971-02-07T06:08:44, which seems rather weird to me. Regards, Roland

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

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.

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

Right. In the first case, you have interpreted "midnight on Tuesday 10 August" as 2010-08-10 + 24 h, with the switch of local time to 2010-08-10 + 23 h, in the second case, you have interpreted "on Thursday 9 September" as 2010-09-09 + 00 h, rather than as 2010-09-09 + 24 h with the switch of local time to 2010-09-09 + 25 h. This is inconsistent and, in my opinion, differs from the intended meaning of the source(s). It is certain that Ramadan will end only on the eve of 2010-09-09 in Egypt. Of course, one might say this is just one hour over one day. But for historical accuracy, other evidence (such as local reporting and air traffic schedules) should be considered before the matter is decided to the nearest minute. The tz database is really a great resource, but it lacks a systematic method to designate the uncertainty of its data (besides the comments). Regards Michael Deckers.
