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.
