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 Because that number looks like HHMMSSYYYY format. http://php.net/manual/en/datetime.formats.php strtotime has to assume that what you pass is supposed to be a date/time string of some sorts. Garbage in, garbage out.
