ProDOS year ranges (was: No-Slot Clock)

["Paul R. Santa-Maria" <paulrsm@ameritech.net>]

I have read that tech note, and I have always thought that Apple chose the
wrong range just to be compatible with the Macintosh.  The system clock is
suposed to to tell you what the time is right NOW.  How many Apple IIs
existed from 1940 to 1975?  A reasonable date range would be 00 to 79 being
2000 to 2079 and 80 to 99 being 1980 to 1999.

That is just the system clock.  How an application stores and handles dates
is an entirely separate issue.
