In case it wasn't clear, I was mostly guessing there. So I dug a bit
further, and indeed, I am wrong. Linux never bumped to a 64-bit time_t
on i386 because of the ABI headaches.
That being said, I still think the "clamp to time_t" strategy is
reasonable. Unless you are doing something really exotic like pretending
to be from the future, nobody will care for 20 years. And at that point,
systems with a 32-bit time_t are going to have to do _something_,
because time() is going to start returning bogus values. So as long as
we behave reasonably (e.g., clamping values and not generating wrapped
nonsense), I think that's a fine solution.
