#44106 [Opn->Bgs]: date_create with '@'timestamp ignores timezone

ID: 44106 Updated by: derick@php.net Reported By: phpbugs at rootcrew dot net -Status: Open +Status: Bogus Bug Type: Date/time related Operating System: Linux (Ubuntu/Debian) PHP Version: 5.3CVS-2008-02-12 (snap) New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Using @ with a time stamp, implicitly uses UTC as timezone. The default timezone or the timezone passed as 2nd argument will only be used if no TZ is associated with the string. As @ already makes UTC associated with it, they are ignored.
