int mktime(int hour, int minute, int second, int month, int day, int year);
it returns long integer, but it "wraps" between 2038-2039

<?php echo mktime(0,0,0,1,1,"2038") ?>
result: 2145913200

<?php echo mktime(0,0,0,1,1,"2039") ?>
result: -1

This is a Unix limitation because of the way the time is represented.
2038 is the year when the number of seconds since 1970 will overflow.
