Western Sahara

From Gwillim Law (2013-10-22):
A correspondent who is usually well informed about time zone matters
... says that Western Sahara observes daylight saving time, just as
Morocco does.

From Paul Eggert (2013-10-23):
Assume that this has been true since Western Sahara switched to GMT,
since most of it was then controlled by Morocco.
