ng. You're likely on your own verifying patches to 4.2.0 work as intended. NTP's maintainers have enough work to keep us busy with the latest ntp-stable and ntp-dev. Good luck and best wishes in your efforts to stay on 4.2.0, which is nearin

and 1e6. The paired errors cancel out, unless you override tick from ntp.conf. If you do, be aware this means the units of tick are milliseconds on nanosecond-resolution systems, not the documented seconds. The units are seconds on microsecond-resolution systems. Cheers, Dave Hart _

ned in terms of the time to read the system clock, as ntpd reads it. As you have noted, ntpd "fuzzes" every timestamp read from the system clock by using random bits instead of whatever the system clock returned for bits beyond the measured precision. This is clearly so that ntpd's calculations, and the calculations of remote clients, are not influenced by what amount to garbage bits returned by the system clock. Over repeated samples, the random bits will average to the middle value, which is the most accurate representation of the clock as readable by ntpd. I hope this help you understand NTP precision. I also hope you will cease attempting to conflate it with any other definitions of "precision" or related terms.
