This depends on how software decides to display "<NO DATE>" or
equivalent.  I'd say it should only apply if both the date and time
fields are zero, but I can see that some programs may have simplified
the check.  I don't recall an official definition.

So don't use your Apple II on 1st January 2000 (assuming you are
conscious).  :-)

Incidentally, ProDOS-8 technical note 28 defines year 0 as 2000 (the
valid range is 40-99 for 1940-1999, then 0-39 for 2000-2039).
