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

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

Ah, but this makes all the distinction between precise and approximate figures. Picoseconds matter to the atomic clocks!

mhmm! that was exactly why I checked - always interesting when such fine measurements make a difference
