There was a similar question recently: https://listengine.tuxfamily.org/chrony.tuxfamily.org/chrony-users/2020/01/msg00004.html > Would it be possible to do the initial sync with a single request per server? > If so how would this be done and what would the drawback be? The current development code in git supports a single-sample selection/update mode, enabled by setting maxsample to 1, but it's meant to be used only in the "ntpdate" mode (-q/-Q option) as it doesn't adjust the frequency of the clock. You could use it for the initial correction before normally starting chronyd. # chronyd -q 'pool pool.example.com maxsamples 1 iburst' -- Miroslav Lichvar -- To unsubscribe email chrony-users-requ...@chrony.tuxfamily.org with "unsubscribe" in the subject.
