The more I look into this the more I start to think it may not be a php bug as I first guess. php is relying on tzdata package so it should follow what tzdata bundle has in hand.
I wonder if the change I mentioned in Comment#1 is valid and/or if it has the appropriate informations for "America/Godthab", because for the moment it seems to share similar value as southamerica locations "America/Sao_Paulo" which I wonder if this could be the reason why it conflicts. If it's not conflicting or something not well taken into account. Note that if I set the localtime to "America/Sao_Paulo", I don't see any conflict. So it is really when "America/Godthab" is set and/or possibly other invented 'europe' abbreviation adjust in the same commit. @Thomas, At this stage, I would contact upstream ML (if any) or the author of the patch : Paul Eggert <egg...@cs.ucla.edu> ---------------------- # filename: europe Zone America/Godthab -3:26:56 - LMT 1916 Jul 28 # Nuuk -3:00 - -03 1980 Apr 6 2:00 -3:00 EU -03/-02 # filename: southamerica Zone America/Sao_Paulo -3:06:28 - LMT 1914 -3:00 Brazil -03/-02 1963 Oct 23 0:00 -3:00 1:00 -02 1964 -3:00 Brazil -03/-02 ---------------------- # strings /usr/share/zoneinfo/America/Sao_Paulo <-03>3<-02>,M10.3.0/0,M2.3.0/0 # strings /usr/share/zoneinfo/America/Godthab <-03>3<-02>,M3.5.0/-2,M10.5.0/-1 ---------------------- # ln -sf /usr/share/zoneinfo/America/Sao_Paulo /etc/localtime # date Mon Dec 4 13:53:33 -02 2017 # php tz.php America/Sao_Paulo -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734967 Title: tzdata info for WGT/WGST broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1734967/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
