There is a mod_perl gotcha here... The file test operators calculate their deltas based on the "scripts" starting time. Under normal situations this works fine, but with mod_perl it can cause problems, since the starting time may have been weeks ago. (leading to values such as "This file was modified -5.24 days ago") Resetting the $^T variable to the current time will fix this.

$^T = time();
$age = -M $file;

Of course, if it is straight CGI, you don't need to worry about it.
