FYI/A
A Leap Second will be added to the world’s clocks at 2016/12/31 23:59:59/60 UTC.
Owing to the fortuitous operation of the rotating globe, this will happen at lunchtime NZ Time (noon or 13:00, depending on how NZ Summer Time works) on New Year’s Day 2017, so will more likely affect our post-prandial nap than interrupt
our New Year revels
Details below sig block.
Happy New Year 2017

Paris, 6 July 2016 Bulletin C 52
To authorities responsible for the measurement and distribution of time UTC
TIME STEP on the 1st of January 2017
A positive leap second will be introduced at the end of December 2016. The sequence of dates of the UTC second markers will be:
- 2016 December 31, 23h 59m 59s
- 2016 December 31, 23h 59m 60s
- 2017 January 1, 0h 0m 0s
The difference between UTC and the International Atomic Time TAI is:
- from 2015 July 1, 0h UTC, to 2017 January 1 0h UTC : UTC-TAI = - 36s
- from 2017 January 1, 0h UTC, until further notice : UTC-TAI = - 37s
Leap seconds can be introduced in UTC at the end of the months of December or June, depending on the evolution of UT1-TAI.
Bulletin C is mailed every six months, either to announce a time step in UTC or to confirm that there will be no time step at the next possible date.
