Actually, I'd think that the cp/m 3.0 "type" stamps that are
actually cp/m 3.0 compatible would be the most portable.  It would
allow 2.2 users to be compatible with the already existing standard
as defined by DRI in CP/M 3.0.

With a timestamp compatible with CP/M 3.0, ALL CP/M-80's would use a
single format!  existing CP/M 3.0 utilities (such as UNIX-like "make")
may be usable by 2.2 users (see the CPM3 section of Simtel20 archives).
