PS. Not sure if this have anything to do with it (the message mentions CPU
time, not the clock), but I'm running a ntp daemon, to synchronize time...
Highly likely it has a Lot to do with it :-) Maybe the master time
server had `date` run manually, or otherwise shifted, or came back
on net after an outage, & the systems noticed drifted time & corrected etc.
man ntpd
man ntp.conf
etc :-)
AFAIK, under normal circumstances ntpd should never reset the current
time the hard way. Ntpd slows down (slews) or increases (steps) the
speed of your clock, such that it will catch up or fall behind enough to
become in line with the ntp servers it is listening to (since resetting
the time the hard way is usually not a good idea; think makefiles,
cronjobs that could run twice, etc..). You could check out the -x flag
to nptd, to prevent setting the clock the hard way all together (since
network congestion and stuff like that might result in ntpd setting the
clock the hard way).
