About 28 minutes ago, the first leap second in seven years was inserted. The clock went from 23:59:59 UTC to 23:59:60. Here in Oregon, this happened at 15:59:60. This was done to keep UTC in sync with the sun. The difference between atomic time (TAI) and UTC is now 33 seconds.
Linux handled this automatically. My home server printed out:
Clock: inserting leap second 23:59:60 UTC
