Thank you for the heads-up.  Can you please point us at a local,
reliable source for this news?  Presumably timeanddate.com got it from
somewhere.  An English-language source would be preferred, but Arabic
is OK.

The Wikipedia article "Daylight saving time in Morocco"
<http://en.wikipedia.org/wiki/Daylight_saving_time_in_Morocco>
says "starting in 2012, clocks shall be advanced 60 minutes at
02:00 on the last Sunday of April of each year, and return to UTC
at 03:00 on the last Sunday of September of the same year, with
the exception of the holy month of Ramadan, during which DST will
not be observed."  But the sources it cites don't actually seem to
say this.

Which raises the question: how is Ramadan determined in Morocco?
Is it a government decree long in advance, or is it decided based on
visual sightings of the crescent moon?  If the latter, it's going
to be hard for us to predict the daylight-saving transitions.
