During 1971, UTC was running 3 millionths of a percent (0.94608 seconds) slower than TAI. Plus, we inserted 0.107758 seconds at the end

There is a 26-way tie for "longest day". Any day with a leap second is 86401 seconds long. There's another one coming up on 31 December 2016

The shortest day was 31 January 1968. It ran for 86399.902592 seconds

During 31 January 1968, UTC ran 3 millionths of a percent (0.002592 seconds) slower than TAI. But we removed 0.1 seconds from the end

Correction, I meant to say "TAI ran 3 millionths of a percent faster than UTC" above. Both times. Figures are correct though

Here is the code I used to work out those year lengths https://gist.github.com/ferno/d92f218ab51bcecdd1075fa1e1fd07b6 …

And here is the code for those day lengths https://gist.github.com/ferno/ecfcf88206f984a5fa8bcb73d6d505f9 …

For reference, a typical 24-hour day runs for 24*60*60 = 86400 seconds, and a typical 365-day year runs for 86400*365 = 31536000 seconds
