Under normal circumstances, you shouldn't see this out of a clock adjustment that NTP makes. If you are, there are two likely possibilities: - Some other process (like timed?) did a tickadj() system call, and when the xntpd daemon did it's adjustment, it's seeing the residual delta. - The value of "tick" in the kernel is inconsistant with what xntpd is prepared to deal with. Possibly the "tickadj" program can correct this. Generally, xntpd will perform a series of adjustments to gently slew the clock; it's won't crank in more clock slew per interval than it believe the kernel can actually adjust. louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
