Doc #65747 [Com]: DateTime __construct error

Edit report at https://bugs.php.net/bug.php?id=65747&edit=1 ID: 65747 Comment by: gabri dot ns 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: 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} Previous Comments: ------------------------------------------------------------------------ [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 ------------------------------------------------------------------------ [2013-09-23 23:44:15] mwiseman at dogandtuba dot com Description: ------------ Constructing a DateTime object with a string argument of 1 character creates a DateTime object set to now, instead of throwing an exception. If the string contains two characters (e.g. DateTime('aa')) an exception is thrown. Test script: --------------- <?php date_default_timezone_set('America/Los_Angeles'); $d = new DateTime('x'); echo $d->format('y-m-d'); ?> Expected result: ---------------- Throw an exception Actual result: -------------- Valid DateTime object set to now. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65747&edit=1
