The consequences have been quite far reaching from that original decision: it's one of the reasons clock_gettime() has clocks for finding out whether it's time for lunch and clocks for determining how long lunch actually lasted.   Less prosaically, it's why at least one program that used getttimeofday() as an interval timer panicked when an sub-second interval not so much short as negative.  (The bug is now fixed, but the hideous workarounds are still being employed because no one is sure if it is actually fixed and no one wants to find out one dark and stormy night.)

Ok, I have to ask: what was the program?

And, thank you to all who have been contributing to this intriguing and most illuminating discussion.

Cheers!
