Description of problem: The Moroccan government is currently deciding whether to reintroduce Daylight Saving Time as of _this weekend_. If they do decide to reintroduce DST, tzdata updates will be needed on very short notice, similar to the recent changes for Turkey (cf. <https://access.redhat.com/kb/docs/DOC-49007>). Press coverage: <http://www.map.ma/eng/sections/home/morocco_to_spring_fo/view>. Frontline support is working to obtain clarification of the status of this potential change and this bugzilla report will be updated accordingly. Version-Release number of selected component (if applicable): tzdata-2011d-1.el6.noarch How reproducible: If this decision is finalised, 100%. Steps to Reproduce: zdump -v Africa/Casablanca | grep 2011 Actual results: Empty Expected results: If this decision is finalised: Africa/Casablanca Sat Apr 2 23:59:59 2011 UTC = Sat Apr 2 23:59:59 2011 WET isdst=0 gmtoff=0 Africa/Casablanca Sun Apr 3 00:00:00 2011 UTC = Sun Apr 3 01:00:00 2011 WEST isdst=1 gmtoff=3600 plus two more lines for the end of DST in 2011 - data not known presently.
(In reply to comment #1) > plus two more lines for the end of DST in 2011 - data not known presently. Read the source, Ray. Expected results: Africa/Casablanca Sat Apr 2 23:59:59 2011 UTC = Sat Apr 2 23:59:59 2011 WET isdst=0 gmtoff=0 Africa/Casablanca Sun Apr 3 00:00:00 2011 UTC = Sun Apr 3 01:00:00 2011 WEST isdst=1 gmtoff=3600 Africa/Casablanca Sun Jul 31 23:59:59 2011 UTC = Sun Jul 31 23:59:59 2011 WET isdst=0 gmtoff=0 Africa/Casablanca Mon Aug 1 00:00:00 2011 UTC = Mon Aug 1 01:00:00 2011 WEST isdst=1 gmtoff=3600 (I think)
A Moroccan customer contacted by GSS has confirmed that DST will be reintroduced; unfortunately, we have not identified an official resource confirming this - <http://www.maroc.ma/PortailInstAn/templates/get_all.aspx> does not discuss it, <http://news.gmane.org/gmane.comp.time.tz> has nothing yet. As best as I can tell, the following lines need to be added to the "africa" source file to cope with this change: Rule Morocco 2011 only - Apr 3 0:00 1:00 S Rule Morocco 2011 only - Aug 1 0:00 0 -
"Direction Réglementation de l’ANRT" (the national telecommunications regulator) has provided clarification: www.map.ma is an official website, publishing official notes only. Thus, the following is authoritative: http://www.map.ma/eng/sections/home/morocco_to_spring_fo/view
This is now reported on the upstream tz mailing list as well; thread start <http://article.gmane.org/gmane.comp.time.tz/3682>.
Thanks. The patch seems right to me, assuming the DST ends at midnight, too.
(In reply to comment #8) > The patch seems right to me, assuming the DST ends at midnight, too. Historically, that has always been the case: # grep 'Morocco' africa | grep -- '-$' | cut -f 8 | sort | uniq 0:00 In any case, the precise end of DST isn't the immediate concern here.
(In reply to comment #6) The proposed upstream changes have been posted: <http://article.gmane.org/gmane.comp.time.tz/3683>. Note that these include changes for several other locations as well.
