We've Nagios monitoring a majority of our NTP devices. Around the
appropriate time I got a pretty big flurry of ntp sync warnings, took about
half an hour for everything to get in sync. Everything looks normal as of
right now (has been for a while).
I hadn't thought to turn off the alarms even though I was aware of the
leap. That resulted in a lot of notifications going out to our on-call
people.
