The longest year to date is 1972, which was a leap year AND the only year in history to have TWO leap seconds. 366 days, 2 seconds

The longest non-leap year is 1971. It ran for 365 days, 1.053838 seconds

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 …
