quarantine 'em

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

The basic problem here is that the planet Earth is a terrible clock

It spins too slowly, it spins at irregular rates, it is constantly slowing down, and it can never be wound

Vibrating caesium atoms are much more reliable, and that's where we derive atomic time from

Unfortunately, for the purposes of civil timekeeping, the rotation of the Earth is all that matters, and nobody cares about caesium atoms
