A problem-handling scheme with more than 2038-year timestamp in PHP

PHP valid timestamp Typical range is GMT December 13, 1901 20:45:54 to January 19, 2038 03:14:07. (This range conforms to the minimum and maximum values of a 32-bit signed integer). However, this range is limited to some systems (such as Windows) from January 1, 1970 to January 19, 2038 before PHP 5.1.

The 64-bit system will not be affected if the 32 system can be resolved using the new datetime

The code is as follows:
$date = ' 2090-10-01 ';
$datetime = new DateTime ($date);
Echo ' <p> normal Time: ', $datetime->format (' y-m-d h:i '), ' </p> ';
Echo ' <p> time overflow: ', date (' y-m-d h:i ', Strtotime ($date)), ' <p> ';

Because the server now use Win2003 is still quite a lot of, so the applicability of this solution is very wide, I hope we can enjoy.
