Bug #73239 [Ver]: DateTime constructor throws exceptions when it should not

Edit report at https://bugs.php.net/bug.php?id=73239&edit=1 ID: 73239 Updated by: derick@php.net Reported by: alec@php.net Summary: DateTime constructor throws exceptions when it should not Status: Verified Type: Bug Package: Date/time related PHP Version: 7.0.11 Block user comment: N Private report: N New Comment: IMO, this message is correct. If you add some *broken* data, you very much should get a notice about this. And Exceptions is how a constructor signals this. Previous Comments: ------------------------------------------------------------------------ [2016-10-04 15:56:04] cmb@php.net Considering that using date_default_timezone_set() instead of ini_set() does not cause the DateTime constructor to throw an exception[1], this inconsistency[2] doesn't make sense.

On PHP7 I can reproduce the issue with invalid date.timezone. It works with empty date.timezone, but it might be environment specific. I have user reports that it throws exception with empty setting. E.g. PHP Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct(): 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 the timezone 'UTC' for now, but please set date.timezone to select your timezone.' in ... This should not happen.The point of falling back to 'UTC' here is exactly to not throw an exception, no? Test script: --------------- ini_set('date.timezone', 'dummy'); $dt = new DateTime('now'); Expected result: ---------------- no exception. Actual result: -------------- PHP Fatal error: Uncaught Exception: DateTime::__construct(): Invalid date.timezone value 'dummy', we selected the timezone 'UTC' for now. in ... ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73239&edit=1
