My spoken French is not all that fluent, but my written comprehension is 
good enough for this:

Rabat- L'heure légale au Maroc sera avancée d'une heure à partir du samedi 2 
avril 2011 à 24h00, indique une source responsable du ministère de la 
Modernisation des secteurs publics.
 Le retour à l'heure normale se fera à compter du dimanche 31 juillet 2011 à 
minuit. L'heure sera retardée de soixante minutes à 24h00 samedi 30 juillet 

Un projet de décret a été élaboré à cet égard et sera présenté lors de la 
prochaine réunion du conseil de gouvernement.


"Rabat--The legal time in Morocco will be advanced one hour beginning 
Saturday, 2 April 2011 at 24:00, says a responsible source at the Mininstry 
of Public Sector Modernisation.
The return to normal time will take place (literally: do itself) starting 
Sunday, 31 July 2011 at midnight.  The time will be turned back sixty 
minutes at 24:00 [on] Saturday 30 July 2011.

A draft of an official statement on this matter has been drawn up and will 
be presented at the time of the next government council meeting."

So it seems that at midnight Saturday the 2nd (= 2011-04-03T00:00:00) it 
will become 2011-04-03T01:00:00, local time in Morocco.  The "fall back" 
time is ambiguous, though.  24:00 on 30 July and midnight on 31 July are the 
same time, namely 2011-07-31T00:00:00.
Assuming the clocks are changing Saturday night, is it 24:00 _after_ the 
time change, or before?

It does not help that they included a picture of clocks changing at 
2:00/3:00 in the article  :((
