I can still 'force' a failure (the 'day' decrements each time the

And, why would having a
lower year (one in the 1700's for instance) make any difference?
I don't have a definite answer, but I do know that time zone data
from the past can be very sketchy which might lead to bugs when
converting back and forth between time zones.
I'd go further than very sketchy. There have been many adjustments
and other changes to date and time over the centuries. The Java
libraries try to take them all into account. Trying to get the
behavior you expect from the classes can be an exercise in
frustration. I have, at times, resorting to doing my own (incorrect)
date math to get the inaccurate but expected result that I wanted.
Dates. Run away!
