Description Travers Carter 2010-06-24 06:35:41 UTC

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)

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
