How would you do it without Perl? NFS? ssh? Windows Networking? If the
file can be accessed normally on your machine (if it's on a networked
filesystem you can access) you can use File::stat (or the stat builtin)
and File::Slurp to do what you ask, although note that unless you are on
Win32 files don't generally have a 'creation time' you can easily read
from Perl. Under Win32 the ctime member of the stat structure contains
the creation time (this is *not* the case under other OSs). If you need
to get at the file more indirectly, you will have to tell us how.

Do that in Perl then. You can invoke rcp (presumably with -p) using
system. Then you can use File::stat and File::Slurp, as I said before.

Perl doesn't have any magic way of getting at files you can't get at
normally.
