I can't confirm the final date for time change, as you know this depends on the new moon of Ramadan appearance as per Hijiri calendar. but most properly it will be at 24 of Sep. 2006. So, if the government decided time change based on the Hijiri system then we also need to change this again on the next year, or it will be fixed time (i.e. no time change between summer and winter).
For me i will generate two files one for 23 and the other for 24, i will apply the 24 file first on my system.
Thank you very much for your support,
Best Regards,
Hassan Hammad

I have just tried to modify the africa file to represent the modification that will probably be necessary for Egypt as per Hammad's info (The Egyptian Gazette, 10th September):

Clocks to turn back
in Ramadan

EGYPT will switch back to the winter
time on the eve of the first day of the
Muslim holy month of Ramadan, expected
to start this year on September 24.
   The beginning of Ramadan, during
which Muslims abstain from food and 
drinking from dawn to dusk, is determined
by spotting the new moon.
   "Clocks will be turned back starting
from the night on which Darul Ifta (the
authority passing Islamic edicts) announces
sighting the crescent of the month of 
Ramadan and the start of fasting," Magdi
Radi, the Cabinet spokesman, said yester-

I believe this modification also fixes the difference between code and final comment for Egypt: the comment says transitions should be at 0:00 except for 1995 but the current code does otherwise. 

Hammad, could you send us some info about the final, definitive alteration? I ask this as per the info you sent, the 24th September isn't final yet.

	Could you send us the new rules? If you could also include some link

	to official information (or non-official) regarding this issue, it

	would also be included in tz's documentation.
