The standard ProDOS clock driver uses the calendar congruence
to compute the year (within a contiguous range of 5 or 6 years,
depending on whether one or two leap years are in the range) by
using the month, day, and day of week.  Getting the day of week
wrong will cause the wrong year to be computed.

ProDOS expects a clock card conforming to the ThunderClock
interface--is that what "standard Apple clock card" means?
Like the doctor said, if it hurts when you change that DIP switch,
then don't change it.  ;-)
