Doc #65747 [Com]: DateTime __construct error

Edit report at https://bugs.php.net/bug.php?id=65747&edit=1 ID: 65747 Comment by: vascowhite at gmail dot com Reported by: mwiseman at dogandtuba dot com Summary: DateTime __construct error Status: Open Type: Documentation Problem Package: Date/time related Operating System: Windows PHP Version: Irrelevant Block user comment: N Private report: N New Comment: 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. Previous Comments: ------------------------------------------------------------------------ [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. ------------------------------------------------------------------------ [2013-09-29 15:56:59] vascowhite at gmail dot com Related To: Bug #65787 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
