As it has in previous years, Morocco suspended its daylight saving time (DST) period for the observation of the Muslim month of Ramadan. On May 21, 2017, clocks turned back at 03:00 to 02:00 to end DST observation.

On July 2, clocks will be set ahead at 02:00 to 03:00 to resume DST observation. DST observance in Morocco will end as scheduled on October 29, 2017 at 03:00. To ensure this transition takes place correctly, we recommend customers install this update. More details about this update can be found here.
