But they step not simultaneous to this offset (which is ~300s), why should some servers have such offset and others not?. Can you provide your "ntpq -c rl" output? If you disable the ntpd, what time drift do you measure per day? > In a old version of Freebsd12, when dev.cpu.0.freq was accessible, the > problem appear when I force the frequency to 1200.
