i have read about 2 methods to sync the time on a freebsd box. 1) add these entries to /etc/rc.conf: ntpdate_enable="YES" ntpdate_flags="us.pool.ntp.org" ... and let the system do a one-time sync at bootup, and rely on this single method for timesync. 2) add this entry to /etc/rc.conf ntpd_enable="YES" add the file with these contents to /etc/rc.conf: server us.pool.ntp.org driftfile /var/db/ntp.drift restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap so, i have a workstation and a server, which i originally did method 1 on, but soon enough, time drifted quite a bit. so i switched it to the 2nd method, and they appear to be sync'd perfectly. a third box i set up, i did only method 2, and this one did not stay synced at all. after i manually ran 'ntpdate -v -b us.pool.ntp.org', this box straightend up. are both methods required for proper time syncronization, or can one rely only on the ntpd method? thanks, Jonathan Horne
