I'm writing code (which may go into NetBSD 1.3.3) to handle the
century byte. Previously NetBSD was largely ignoring this byte, and
simply assuming that a year < 70 indicated a date past 2000.
Many machines fail to set the century byte properly and it is unsafe
for us to depend on it being set, but there is no reason I can't make
the resettodr routine handle setting the century byte properly.
