Okay, I'm going out on a limb (?) here, but, shouldn't
Perl hide that from you ? (Sarcastic, ofcourse it does)
Don't know much about MacPerl, but I think you just
be able to use 'stat' ... And if not *I* think you should

..wait...

oh... I love Google... found this:

#!perl

Hmmm just searched for "Perl Mac stat" on google, do
you have Internet there ?

p.s. From PerlPort on 'stat':
mtime and atime are the same thing, and ctime is creation time instead of inode change time. (Mac OS)
