Description:
------------
While stress-testing our MediaWiki installation (hammering it with many page requests to Special:Random), I saw a few of these in the Apache logs:

PHP Fatal error:  date() [<a href='function.date'>function.date</a>]: Timezone database is corrupt - this should *never* happen! in D:\\mediawiki\\w\\includes\\Parser.php on line 2458

The line is:
$ts = time();
/* ... intermediate lines ... */
$localYear = date( 'Y', $ts );

I found http://bugs.php.net/bug.php?id=39993 which looks related but it supposedly has been closed.

MediaWiki 1.11.0
PHP: 5.2.4 (apache2handler)
MySQL: 5.0.45-community-nt
Apache 2.2.6 (patched version for Windows from apachelounge.org)
Windows 2003 server


Reproduce code:
---------------
Happens while stress-testing, hammering the webserver with thousands of requests from 3 simultaneous clients.


Expected result:
----------------
Bug should not occur.

Actual result:
--------------

Issue also appears in version:
PHP 5.2.6-1+lenny3 with Suhosin-Patch 0.9.6.2 (cli) (built: Apr 26 2009 22:16:23)
Copyright (c) 1997-2008 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies

At the moment I cannot reproduce the issue as it happens at random ( or so it may seem atm ). The script which produces the issue runs constantly under a heavy load ( executes ~25 CURL request per second, burning 5 MBit of bandwidth ).

Any who, I'll post a detailed log next time it happens.
