Hi,
Reaching low millisecond accuracy (or even resolution) might be hard in a
M$WIN environment, where the system timer tick is 10ms. There is also a
Multimedia Timer with 1ms ticks.

someone having a recent reference to time(r) resolution and NTP accuracy
in Windows?
I think you should grab your favorite free unix flavor and the reference
NTP implementation to reach ms accuracy.
