I'm getting PHP notices about undefined constant for DATE_W3C:

PHP Notice:  Use of undefined constant DATE_W3C - assumed 'DATE_W3C' in /home/sergey/www/sites/infeedcontrols.com/w/extensions/SemanticMediaWiki/specials/Export/SMW_SpecialOWLExport.php on line 566

I'm running PHP 5.2.8 and almost latest SMW and MW:

Might be related to some changes in PHP.
