The last time I looked closely at Windows timekeeping, clock "ticks" were every 17 milliseconds or something like that. My desktop system is Windows XP and seems to be within a second or so. I have no requirement for better time than that. My Solaris systems, OTOH, run NTPD and keep time to within a +/- 10 milliseconds over the network. One has a GPS reference clock and its time seems to be within 100 usec or so. It MAY be far better than that but I lack the means to determine how much better. _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
