<elevator to stop working when you're trying to make the appointment on the
<40th floor, would you? Sure, it could fail for other reasons too, but this
<is something that ought to be double-checked since we know about it.
This is exactly the stuff I refer to. Whay would an elevator care what
year it is? Some do days of the week but their clock is not date but _day_
so that say on sunday you need a pass key to get in a building that would be
open during the week. That as far as they go, very minimalistic.
