Date functions erratic in 1960's - perhaps too many drugs around at the time ? Causes me grief with age validation routines. Checked reports - can't see similar report.

All kit local - Apache and PHP build from source trees, no modifications to source (I wouldn't dare!)

Script to cause failure:
<?php
$d4=mktime(0,0,0,09,01,1961);$d4s=date("D d F Y", $d4);
echo "Date was $d4 [$d4s] <br>";
?>

result (should be sep 1st 1961) is Date was -286675200 [Thu 01 December 1960]
