Hi Mirek,
Thank you for the fast reponse. I see you changed the argument name in SetSysTime from ATime to time, could you please also run a search and replace to correct all the references? Wink

Zbych,
My first version actually was calling the gettimeofday part if the call to CLOCK_MONOTONIC was failing, but I don't know if that was correct and I could not test it on any of my systems.
With the macros you found it would be safe to do something like this:

#ifdef PLATFORM_POSIX
dword GetTickCount() {
#if defined(_POSIX_TIMERS) && defined(_POSIX_MONOTONIC_CLOCK)
	struct timespec tp;
	if (clock_gettime(CLOCK_MONOTONIC, &tp) == 0)
	{
		return (dword)((tp.tv_sec * 1000) + (tp.tv_nsec / 1000000));
	}
#endif
	struct timeval tv[1];
	struct timezone tz[1];
	memset(tz, 0, sizeof(tz));
	gettimeofday(tv, tz);
	return (dword)tv->tv_sec * 1000 + tv->tv_usec / 1000;
}
#endif
