Edit report at https://bugs.php.net/bug.php?id=55527&edit=1 ID: 55527 Updated by: cmb@php.net Reported by: john at zerocrates dot org Summary: DateTime::__construct throws Exception even when timezone is specified -Status: Open +Status: Closed Type: Bug Package: Date/time related Operating System: All PHP Version: 5.3.8 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: The exception is due to the warning that the default timezone has not been set. This warning has been removed as of PHP 7[1], so the issue is resolved, see <https://3v4l.org/4iVJ8>. @headsup: this would be another issue, so please open a new ticket. [1] <https://wiki.php.net/rfc/date.timezone_warning_removal> Previous Comments: ------------------------------------------------------------------------ [2014-10-02 08:17:54] headsup at hotmail dot com After a few hundred lines of flawless code, whenever using the method POST (not GET) the function error_get_last() catches the following, despite of setting the timezone in the first line of the code with date_default_timezone_set('Europe/Lisbon'); Array ( [type] => 2 [message] => Unknown: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/London' for '1.0/DST' instead [file] => Unknown [line] => 0 ) Curiously, at the end of the script, after printing the array above, printing date_default_timezone_get() gets me 'Europe/Lisbon', as set in the first line. ------------------------------------------------------------------------ [2011-10-10 00:22:57] john at zerocrates dot org Switching "OS" field to "All", this is OS-independent. ------------------------------------------------------------------------ [2011-08-28 22:23:49] john at zerocrates dot org Description: ------------ The DateTime constructor throws an Exception warning that it is not safe to rely on the system's timezone settings if you try to construct a DateTime object and haven't somehow specified a timezone, whether by using date_default_timezone_set, the date.timezone setting, or the $timezone argument of DateTime itself. However, there is another way to specify the timezone for a DateTime object, by passing a time string which includes a timezone as the first argument to the constructor. When such a string is given, the $timezone argument is ignored and the timezone given in the string is always used. However, this doesn't prevent the Exception from being thrown, even though a timezone is being specified. To avoid the Exception, you have to have a default timezone set, or you have to pass a DateTimeZone as the second argument, even though neither would actually be used for creating the object. Test script: --------------- <?php ini_set('date.timezone', NULL); try { $date = new DateTime('2011-08-28T00:00:00+0000'); echo $date->format('O'); } catch (Exception $e) { echo 'Exception thrown.'; } echo PHP_EOL; date_default_timezone_set('America/New_York'); try { $date = new DateTime('2011-08-28T00:00:00+0000'); echo $date->format('O'); } catch (Exception $e) { echo 'Exception thrown.'; } Expected result: ---------------- +0000 +0000 Actual result: -------------- Exception thrown. +0000 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55527&edit=1
