I think that someone changed some of the timekeeping code to periodically adjust the value of the rtc if ntp is used to update the system time, machdep.disable_rtc_set=0, and the rtc driver hasn't been disabled: http://svnweb.freebsd.org/viewvc/base?view=revision&revision=208297 This is probably what you are seeing. It should occur every machdep.rtc_save_period seconds. It's probably harmless, unless the adjustments are big or erratic, in which case you may want to check your rtc's battery, or the results of your ntp usage. b.
