The Egyptian Gazette, issue 41 090 on 2006-09-18, page 1 now reports that:
EGYPT will turn back clocks by one hour at the midnight of Thursday after observing the daylight saving time since May.
Ouch. Thanks for the heads-up. So they changed their minds again, with only four days' notice? Their new rule is more historically compatible; perhaps that's why. Currently we have them changing at 2006-09-25 at 01:00 local time.
From this news item I assume that it should be 2006-09-22 at 00:00 local time.
I'll CC: this to Hammad Hassan to get his feedback, but the following patch should do the trick. This is in addition to the Syria and Uruguay patches I sent earlier this week. --- africa 2006/09/18 16:58:11 2006.12 +++ africa 2006/09/19 23:38:52 @@ -212,35 +212,13 @@ Rule Egypt 1990 1994 - May 1 1:00 1:00 # Go with IATA starting in 1995, except correct 1995 entry from 09-30 to 09-29.
