Something like every 20 minutes. grep ntp /var/log/messages says this: May 23 10:12:32 lorax ntpd[23862]: time reset -2.848319 s May 23 10:33:39 lorax ntpd[23862]: time reset -2.532815 s May 23 10:53:19 lorax ntpd[23862]: time reset -2.440872 s May 23 11:14:38 lorax ntpd[23862]: time reset -2.573073 s May 23 11:34:10 lorax ntpd[23862]: time reset -2.510191 s That's pretty darned bad... it takes about 10 minutes for ntp to sync up after such an event. >> Are there any other things I can try to get this machine to keep >> better time?
