time-util: encode our assumption that clock_gettime() never can return 0 or USEC_INFINITY

We generally assume that valid times returned by clock_gettime() are > 0
and < USEC_INFINITY. If this wouldn't hold all kinds of things would
break, because we couldn't distuingish our niche values from regular
values anymore.

Let's hence encode our assumptions in C, already to help static
analyzers and LLMs.
