Yes, is very high resolution, but: 1. Some programs not used this for adjusting timestamps, in self implementation of NTP requests. Or using it's without set thread affinity to CPU core. 2. Frequency unstable and floats due to various factors, from CPU consumpion level to powersaving CPU downclocking, PC environment, etc. So coefficients (clocks to msec) must regular recalibrated with precised source. Сertainly in the range of 16 ms, the error will tend to zero _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
