Advice - 2016-2017 leap second

[stan-qaz]

Is there any advise on dealing with the upcoming leap second?

As the Center's notice states, at 23h 59m 59s on December the 31st you'll need to hold off your celebrations while we slip in the unusual time of 23h 59m 60s before ticking over to 2017 January 1 0h 0m 0s.

Hopefully the answer is "no, all will be well" but if there is anything needed I'd rather know now while things are calm.

Last time it came up there was nothing special to do at all.
