Bug description: filectime reports wrong time after Sep 1999. Possible overflow
<?php
$mod_time=date("D M d, Y",filectime("/home/httpd/html/" . $PHP_SELF));
echo "<FONT COLOR=\"#BBBBBB\">Last modified:
$mod_time</FONT>\n";
?>
Above is the offending code. When passed the below file, it prints:
Last modified: Wed Dec 31, 1969"
-rw-r--r-- 1 bojay users 1954 Sep 30 23:22 index.php3
Changing the filesize or timestamp past about Sep 29 doesn't seem to do anything - it's
permanently locked at Dec 31, 1969. It's anybody's guess why.. but I suspect somebody
didn't allocate enough bytes for the epoch value (If memory serves, it's an unsigned long
double) and now it's bit them in the ass. :\
Just so you are sure it isn't my system:
23:37:32
vortex:~$ ssh bofh "date"
