(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. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
