Time zone rules change

[Jesper Norgaard Welen]

Am I missing something obvious here? It seems to me that the article says
that Ramadan presumably will start the 24.th. of September 2006, and on the
eve of that day, they will switch back to winter time. The rule change
should therefore be  Sep 25 0:00  or perhaps  Sep 24 23:00s  (which is the
same). All this of course if we assume that the switch will happen at
midnight as usual.
 
Regards,
- Jesper

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-
day.

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.

 

 

Best regards,
