Mmmm... why not using clock_gettime where available then?
Looking at qemu sources I found this funny function. I always don't
liked very much gettimeofday for such computation. The reason? The main
problem is that this function (time and ftime have same problem) is
bound to local time since midnight. For this reason clock may go
backward when time is adjusted for locale setting (from/to daylight
saving time). For the same reason (I think) my X goes blank for some
seconds when ntp adjust the time... clock_gettime(CLOCK_MONOTONIC, ...)
is posix and don't have this problem.
