We updated Morocco with year-round UTC+1 (except during Ramadan) about a year ago in these commits: https://github.com/eggert/tz/commit/80de44ca0f2349c0f42f12caa943ced8685c3b67 https://github.com/eggert/tz/commit/8539a448ebc8897e40d62f16dc4d0ada3f07b3ca If there are still errors in tz for Morocco in 2018g or later, please let us know. Otherwise, it sounds like you need to update your time zone definitions with a more recent version. -- Tim Parenti On Mon, 30 Sep 2019 at 11:40, Naoufal Semlali <N.Semlali@iam.ma> wrote:
Good Morning,
I want to inform you that Morocco is not concerned by the transition to the winter time which will take place in Europe on the night of Saturday, October 26 to Sunday, October 27, 2019.
Morocco's schedule must stay on GMT+1
The schedule change take place only before and after the month of Ramadan.
Best Regards

Hello,
The predictions below seem to be correct based on the latest official declarations of the Moroccan government.
Of course, if there will be any change, we will keep you informed.
Thanks.

Please confirm also that the switch to GMT+1 on Sunday, June 9th 2019
at 2 am is already implemented in the tzdata.
Yes, I checked that too.
For what it's worth, here are the tzdata 2018h-and-later predictions for Africa/Casablanca through the year 2037. The columns are the date, the hour just after the transition, the UTC offset just after the transition, and (optionally) 1 if (negative) DST is in effect. These predictions could well be wrong: if you have better info please let us know.
