Therefore you want to use ntpdate to step the clock if needed at boot time. (That is too simple of a description, the algorithm for stepping is more involved.) 'ntpdate' runs at boot time before ntpd is started to make sure the time is close enough for ntp to sync. If you have been having trouble or copied a system from another system with a different hardware clock then the drift file may be too far off. Best to remove it and force ntp to deduce the hw clock drift again. rm /var/lib/ntp/ntp.drift Verify the ntp servers are correct and useful to you. /etc/default/ntp-servers # used by ntpdate /etc/ntp.conf # listed as 'server' or 'peer' in file. Verify that your ntp daemons are happy. Have them print their status. Check that the delay, offset and jitter fields are low, <10.0 for jitter is probably okay. It is okay to have some high delay and jitter servers as long as at least some are low. ntpq -p Bob
