[tz] Will Morocco switch from +01 to +00 during Ramadan next year?

Personally, I feel like it is premature to bring back the Ramadan DST suspension period.  The cited articles appear to be opinions and surveys only.   I would like to see something, anything, from an official source saying that they will do this before it is released in the tzdb.

Thanks for the info. I installed the attached patches into the development version on GitHub to implement this. This patch doesn't exactly agree with the dates you specified (for 2019 it guesses falling back Sunday, May 5 and springing forward Sunday, June 9), but these dates are approximate until an official announcement and a methodical guess is better than no guess at all.

Java users, please note that this patch uses negative DST in the main and vanguard formats; in rearguard format Morocco stays in the +00 timezone (instead of moving to +01 last weekend) and observes positive DST in every month but Ramadan.
