I use a "brute force" method. I have a root crontab executed program, "settime". It calls a National Bureau of Standards telephone number in (I think) Fort Collins, CO every three days or so, after mid-night. The NBS server sends bytes to settime and measures the echo delay. Based on the delay, it sends an adjusted time and settime sets the FreeBSD clock. Accuracy in the 10 millisecond range. Check the "ports" distribution for "settime". If you can't find it, let me know and I'll hunt down and send the source to you. BTW, the call costs me $0.17 from San Diego, CA Ron On 23-May-97 Joseph Stein wrote: >>I have a cron job setup to poll several timeservers with ntpdate to keep >the clock on my machine somewhat current. > >However, everytime the clock is sync'd, it is adjusted by -4.xxx seconds. > >Is there a way to tune the clock a little better? > >If so, how, > >and if the answer is xntpd, how to set it up without the authentication??? > >Thanks in advance for your help, > >joe ---------------------------------- E-Mail: ron@cts.com Date: 05/24/97 Time: 12:13:26 This message was sent by XF-Mail ----------------------------------
