Bug Description

Binary package hint: tzdata

Egypt recently changed its daylight saving time schedule to end at midnight, 21 August 2009 (see http://www.timeanddate.com/news/time/egypt-dst-ends-2009.html). Therefore my system should now be displaying the local time in Egypt as UTC+2, but it is still displaying UTC+3.

I can confirm that this is the case. The output from "date" reads:

Sat Aug 22 11:31:48 EEST 2009

The time is actually 10:31:48 presently but the timezone is correctly indicated here as EEST.

This is also a bug problem in Debian Lenny/Stable, FYI.

I found the line (#280) in the source that contains the problem:

Rule Egypt 2009 only - Sep lastThu 23:00s 0 -

This should be changed to:

Rule Egypt 2009 only - Aug 20 23:00s 0 -
Rule Egypt 2010 max - Sep lastThu 23:00s 0 -

The above two lines reflect the actual end of daylight savings this year and the probable end next year. Egypt changed the end of DST this year to happen just before the beginning of the Islamic Hijri month of Ramadan, which this year began on Saturday 22 August, the time shift occurred at midnight on Thursday 20/Friday 21 August and changed the clock back one hour to 23:00 Thursday 20 August. Next year the government will likely revert to their standard shift date which is at the end of September.
