Actually, the current code says "23:00s", which is 00:00 the next day.
It uses "23:00s" rather than "24:00" because older versions of the
tz package didn't support "24:00".

Yes, that would be helpful, especially exactly what time of day the
clocks are supposed to be moved back.
It won't be final until the crescent moon is sighted that day, alas.
But given the semi-official prediction, and the fact that the change
takes effect this weekend, I think we can change the tz database now;
if we're off by a day, we can change it later.
Here's a proposed patch. I read my copy of the Egyptian Gazette from
<http://www.algomhuria.net.eg/gazette/1/> but this looks like a fairly
temporary URL so I omitted it from the database. Also, I'm assuming
this is a one-time thing since the first day of Ramadan doesn't
necessarily occur near the start of autumn.
Thanks for the heads-up, Hammad.
