True.  ;-)

Although I tried one, I never actually _used_ it.  ISTR that it
modified the filename matching rules to exclude the date, so
that a SAVE to a given filename (minus a date & time) would
be saved with a filename including the date & time, and if
that same file existed with the non-date & time name, it
would be overwritten.

(There was some way to force "normal" full filename
matching, too--like adding a trailing space to a filename or
something--so that multiple versions could be kept.)

Like some of the CP/M 2.2 date/time patches, the result was
not as tidy as you might like, but usable for some purposes.
