Neither. You can do it inside the db with a "pl" language such as plperlu:
CREATE OR REPLACE FUNCTION filemodtime(TEXT) RETURNS TEXT LANGUAGE plperlu AS
$$
my $filename = shift;
-e $filename or elog(ERROR, qq{The file "$filename" does not exist\n});
return localtime($^T - (60*60*24* -M _));
$$;
SELECT filemodtime('/var/log/messages');
SELECT filemodtime('/dark/matter');
