Edit report at https://bugs.php.net/bug.php?id=65747&edit=1 ID: 65747 Updated by: cmb@php.net Reported by: mwiseman at dogandtuba dot com Summary: DateTime __construct error -Status: Open +Status: Verified Type: Documentation Problem Package: Date/time related Operating System: Windows PHP Version: Irrelevant -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: For reference, requinix' script from above with its output: <https://3v4l.org/1sqnT>. Previous Comments: ------------------------------------------------------------------------ [2013-12-18 22:59:40] vascowhite at gmail dot com That doesn't explain why DateTimeZone::construct() doesn't recognise a valid time zone like 'z', nor does it explain why $dateTime = new \DateTime(null, 'z'); raises an exception. If 'z' is a valid tz, it should not. There is a bug in there somewhere. ------------------------------------------------------------------------ [2013-09-30 06:43:46] gabri dot ns at gmail dot com It is not a bug, but a feature that not documented. As requinix says, single character could be mean military time zone. for example Z1500 mean 15 o'clock current date at GMT. Test script: --------------- echo date('Y-m-d H:i:s', strtotime('Z1500')); Actual result: -------------- 2013-09-30 22:00:00 my time zone is +7 please try to take a look at this documentation http://php.net/datetime.construct http://php.net/datetime.formats http://php.net/datetime.formats.time btw, thus single char timezone is already documented. take a look at tz format.. it declared as [A-Za-z]{1,6} ------------------------------------------------------------------------ [2013-09-30 06:24:13] vascowhite at gmail dot com Is the bug in the constructor of DateTimeZone then? This does not recognize the single letter timezones. $tz = new \DateTimeZone('z'); Will raise an exception. ------------------------------------------------------------------------ [2013-09-30 03:09:56] gabri dot ns at gmail dot com IMO, the one that should be fixed is strtotime documentation, since this behaviour came from thus function. As doumentation say, the first argument should be time string, that -i think- will be parsed by strtotime function. Test script: --------------- echo date('Y-m-d H:i:s',strtotime('now'))."\n"; echo date('Y-m-d H:i:s',strtotime('a'))."\n"; Actual result: -------------- 2013-09-30 10:07:18 2013-09-30 16:07:18 ------------------------------------------------------------------------ [2013-09-29 22:43:05] requinix@php.net Expected but undocumented behavior. Single characters correspond to military timezones. See http://en.wikipedia.org/wiki/List_of_military_time_zones foreach (range("a", "z") as $l) { if ($l == "j") continue; printf("%s = %s\n", $l, (new DateTime($l))->format("r")); } So the list of timezones documentation should be updated to mention these. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
