Root directories don't even *have* mod-dates under ProDOS 8, unfortunately.
GET_FILE_INFO on a volume name always (as far as I've ever seen) returns
zero for the mod-date.

Right--many applications *don't* bother propogating mod-date changed back
up the directory tree.  (My own stuff doesn't even do it.)
