Thank you for taking the time to write to us, but this is not
a bug. 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

PHP only does 32bit signed integers, which run out somewhere in the year 2038 (not 2028), and then it rolls over to negative numbers - hence your warning. This won't be changed in PHP 4.4 or 5.0, but is addressed in 5.1 and higher.

If I upgrade 5.1 and higher then Will I have to rewrite all codes for the new verision of PHP?
