I recently migrated some php scripts from a box running php 4.4.4 to php
5.2.5. due to the nature of the data, some of the php scripts require
handling dates before 1901. both boxes are 64-bit (original and new),
however the new box isn't handling dates properly before 1901 with
either the mktime() or strtotime() functions. it was working perfectly
on the old box and I'm stumped as to why it stopped working on the new
one. did the mktime() and strtotime() functions in php 5 regress to
handling the dates as 32-bit ints?
here's an example of some php code to test between the two boxes:
<?php
echo "12-13-1901: ".mktime(0,0,0, 12, 13, 1901)."\n";
echo "12-14-1901: ".mktime(0,0,0, 12, 14, 1901)."\n";
echo "1-18-2038: ".mktime(0,0,0, 1, 18, 2038)."\n";
echo "1-19-2038: ".mktime(0,0,0, 1, 19, 2038)."\n";
echo "12-13-1901: ".strtotime("12/13/1901")."\n";
echo "12-14-1901: ".strtotime("12/14/1901")."\n";
?>
output of code on old box:
12-13-1901: -2147529600
12-14-1901: -2147443200
1-18-2038: 2147414400
1-19-2038: 2147500800
12-13-1901: -2147529600
12-14-1901: -2147443200
output of code on new box:
12-13-1901:
12-14-1901: -2147443200
1-18-2038: 2147414400
1-19-2038:
12-13-1901:
12-14-1901: -2147443200
thanks much ...
