Localtime returns an array based on a "seconds since the epoch"
timestamp; stat also returns an array, the 10th field of which is the
last modification time of a file in such a form.  You can find
documentation for perl functions at http://perldoc.perl.org/

Presuming $r is an Apache2::RequestRec object (which it almost
certainly is, this is available in mason with
HTML::Mason::Request->instance), $r->filename is the name of the file
requested from the HTTP GET request which initiated the transaction.
You can find the documentation for Apache2::RequestRec at CPAN:

http://search.cpan.org/~pgollucci/mod_perl-2.0.3/docs/api/Apache2/RequestRec.pod

I'd recommend asking general perl questions at a forum
such as www.perlmonks.org, where you will get a much more immediate
response.
