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. 2019-05-05 02 +00 1 2019-06-09 03 +01 2020-04-19 02 +00 1 2020-05-24 03 +01 2021-04-11 02 +00 1 2021-05-16 03 +01 2022-03-27 02 +00 1 2022-05-08 03 +01 2023-03-19 02 +00 1 2023-04-23 03 +01 2024-03-10 02 +00 1 2024-04-14 03 +01 2025-02-23 02 +00 1 2025-04-06 03 +01 2026-02-15 02 +00 1 2026-03-22 03 +01 2027-02-07 02 +00 1 2027-03-14 03 +01 2028-01-23 02 +00 1 2028-02-27 03 +01 2029-01-14 02 +00 1 2029-02-18 03 +01 2029-12-30 02 +00 1 2030-02-10 03 +01 2030-12-22 02 +00 1 2031-01-26 03 +01 2031-12-14 02 +00 1 2032-01-18 03 +01 2032-11-28 02 +00 1 2033-01-09 03 +01 2033-11-20 02 +00 1 2033-12-25 03 +01 2034-11-05 02 +00 1 2034-12-17 03 +01 2035-10-28 02 +00 1 2035-12-02 03 +01 2036-10-19 02 +00 1 2036-11-23 03 +01 2037-10-04 02 +00 1 2037-11-15 03 +01
