(curiosity) As I understand, it saves the calibration it has learned, and starts with the same calibration the next time xntpd starts. Should save some work getting back into sync. I leave xntpd running when I drop my PPP connection because it continues to apply its corrections to the clock but knows not to alter the drift values. This way my clock is within 500ms when I reconnect the next day. Otherwise its about 8 seconds/day off. Have to kill the old xntpd when my IP address changes as its not smart enough to follow dynamic IP addresses. -- David Kelly N4HHE, dkelly@tomcat1.tbe.com (wk), dkelly@hiwaay.net (hm) ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
