Looking at the php-src git log (PHP upstream). I notice PHP is updated every time there is a new tzdata version:
56269af46c Updated to version 2017.2 (2017b) 1f9e5cc2bc Updated to version 2017.2 (2017b) eb13003f6c Updated to version 2017.2 (2017b) root@phpbisect:~/php7/php-src# git log --oneline --grep="2017a" b20879348a Updated to version 2017.1 (2017a) 1b16fb594f Updated to version 2017.1 (2017a) dfcb11d7d1 Updated to version 2017.1 (2017a) ---------------------------------------------------------------------- $ git log --oneline --grep="2017c" 973c1e3c93 Updated to version 2017.3 (2017c) 12e2fc4ab6 Updated to version 2017.3 (2017c) b07b526b95 Updated to version 2017.3 (2017c) b2dfcb30eb Updated to version 2017.3 (2017c) $ git log --oneline --format=%cd --date=local --grep="2017c" Mon Oct 23 14:31:24 2017 Mon Oct 23 14:31:23 2017 Mon Oct 23 14:31:21 2017 Mon Oct 23 14:31:20 2017 I'll give it a try in Ubuntu by merging the needed change and test. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to tzdata in Ubuntu. https://bugs.launchpad.net/bugs/1734967 Title: tzdata info for WGT/WGST broken Status in php5 package in Ubuntu: New Status in php7.0 package in Ubuntu: New Status in php7.1 package in Ubuntu: New Status in tzdata package in Ubuntu: Invalid Status in php7.0 package in Debian: New Bug description: Using "America/Godthab" timezone, "WGT/WGST" is no longer displayed from date command but instead just "-03". Problem is evident in PHP applications too, which now think we're in Sao Paolo. This appears to have changed with latest tzdata update or perhaps in combination with change from DST. Same problem on 16.04, 17.10 and Debian 9.
