Well, to avoid boring other people, could you describe the process in a private message? Sounds interesting for some weird reason.
Sorry for all the questions, my main fault is being new.

I'm collecting the ticks with a millisecond precision, but obviously, I'm limited by the PC's clock timer resolution.
The PC's clock timer interrupt refreshes the time information at a frequency of about 62.5Hz, so it delivers a new time information to the system roughly every 16 ms.
As you can see, the time moves in 16 ms leaps for an IBM PC-compatible computers However, I've seen some interesting solutions on how to cope with this issue of time precision granularity, but it's a theme onto itself.
Actually this is the case with Microsoft Windows only. At least up to XP.
Linux based PC system is not showing such time imprecision.
