    The most annoying thing about timekeeping in computers is, that (unless we're seing 256 bit word sized architectures) you'll always need more bits to conveniently represent time, than fit in a word, but also, that time is not a static value, so you can't conveniently cache away the higher bits.

    As far as I am concerned, the only reasonable way to keep time on a computer is having a 256 bit high precision counter on the CPU, driven from an NCO (so that you can tune the clock to an external precision source) and a dedicated instruction to read that counter at a resolution appropriate for the task at hand.
