how to convert from timestamp to date format in tcsh

hello all
im looking for fast way to convert timestamp format to date format
and vaiseversa in tcsh , can it be done?
thanks allot

Since ls -l output can look like this:

-rw-r--r--   1 user001    admin       2190 Jun 20 12:31 filea
-rw-r--r--   1 user001    admin       3176 Mar 18  2003 fileb

It would be difficult, if not impossible to do. The trick would be to use Perl, since it is the one utility I know of that's widely available that can grab the stat structure. The stat structure contains the date in number of seconds since midnight on 1/1/1970, and can thus be converted easily into whatever format you want.

Do you have perl?
