Well, if you use gettimeofday(), you'd better be cool with time going backwards too, cause it happens rather often.

(hardware/kernel version with malfunctioning timekeeping, also running NTP; NTP will step the time once in a while because it can't keep up with the clock drift. You might say that's uncommon, but not so uncommon that you won't run into it!)
