Thomas Savage reports confusion in Morocco last weekend involving daylight saving time. See: Savage T. Quelle heure est-il vraiment au Maroc? Telquel.ma 2015-09-30. http://telquel.ma/2015/09/30/quelle-heure-il-vraiment-au-maroc_1464578 Savage quotes last month's confusion on the tz mailing list over whether Morocco's fallback transition this year would be Sept. 27 (as an incorrect news report would have it) or Oct. 25 (the official date), and speculates that this confusion led to many electronic devices in Morocco to misbehave on Sept. 27. In thinking about the failure symptoms, though, I guess a more plausible explanation is that the malfunctioning devices were using the equivalent of a tz release somewhere from tzdata 2012c (dated 2012-03-07) through 2013g (dated 2013-09-30), as these older releases predicted that Morocco would fall back the last Sunday in September -- a prediction that was correct in 2012 but incorrect in 2013 through 2015.
