This occurs when the rtc is set, via:


after a verbose boot.  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:


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.
