zone.tab is an adequate substitute - a fact which I thought was
sufficiently obvious as to not be worth mentioning.

The proposed rules I suggested do work almost as well if zone[1970].tab
is absent, though obviously that's not the optimal situation. But are
there any systems which lack it? It's next to impossible to implement a
sane "ask the user what timezone to use" procedure without it.

Yes, you've repeated that point at some length, and I am not convinced.
Is anyone else?
