Red Hat Bugzilla – Bug 607453
php mktime() is limited to 32-bit timestamps (1900-2038) on 64-bit systems
Last modified: 2012-02-21 01:29:43 EST
Description of problem: PHP's mktime() function (and probably other date-time functions) is limited to the 32-bit timestamp range, even on 64-bit platforms (eg x86_64), this is a regression from php 4, where 64-bit timestamps were supported on 64-bit platforms. The problem appears to be a missing "#include <limits.h>" in ext/date/lib/timelib.h, causing it to fall back on a hardcoded 32-bit definition of LONG_MAX. This #include appears to have been added in PHP 5.2.6 http://svn.php.net/viewvc/php/php-src/tags/php_5_2_6/ext/date/lib/timelib.h?view=markup See lines 25-27 of the above Version-Release number of selected component (if applicable): php-5.1.6-27.el5 How reproducible: Always Steps to Reproduce: 1. Run php -r 'var_dump(mktime(1, 1, 1, 1, 1, 2039));' Actual results: bool(false) Expected results: int(2177416861) Additional info:
