To do this, the DST period is suspended during the Muslim month of Ramadan (03:00 on Sunday, June 14, 2015 to 02:00 on Sunday, July 19, 2015, in the Gregorian calendar).
During this period, clocks will be turned back to Standard Time. This suspension of the DST schedule is designed to shorten evenings, making it easier for Muslims to observe the Ramadan fast during hours of daylight. DST will resume at the end of the Ramadan observation on July 19, 2015.
We are releasing two hotfixes to automatically make these changes to the operating system for 2015.
- Hotfix 3062740 sets 03:00 on June 13, 2015 as the DST transition time. This is because of a late-breaking announcement to move the DST transition time back one day. However, because the DST transition has already occurred, this hotfix will correct the current DST state for the Morocco time zone.
- Time zone history does not account for the Ramadan period that is set by these hotfix solutions.
To restore the DST adjustment on all systems, install hotfix 3062741 before June 28, 2015.
Note The announced time zone changes apply only to the 2015 calendar year. To return the system to the default DST settings for Morocco in 2016, you must install the December 2015 cumulative time zone update for Windows when that cumulative update is available.
