Leap second 2016-12-31

Insertion of the 37th leap second on 2016-12-31. Note how 23:59:59 is held for 2 seconds on the displays. The beeps come from our modified-DCF77 AM-coded 25 MHz radio transmitter.

More analysis to come later based on NTP logs. Some stratum-2 NTP servers seemed to take up to 10 minutes to apply the leap second.
