What's wrong with compile-time errors? We have a pretty good understanding
of how time values are passed in the kernel, and we know they will all break
in 2038 for 32-bit kernels unless we do something about it.

I agree the glibc side is harder than this, but we have to get the kernel
into shape first (at the minimum we have to do the APIs), and there is enough
work to do here.
