A quick look at time_recv() shows this is true, and timetz_recv()
checks neither the time nor the zone component.

I'm not entirely sure why we put a range limit on time values at all,
but given that we do, it'd probably be a good idea to check the range
in the recv functions. I'm inclined to fix this for 8.4, but not
back-patch because of compatibility considerations. Any objections
out there?
