How Long Is A Day?

Just a video I found slightly interesting.

Without watching the video. Getting longer each day. Eventually earth sill be tidal locked like the moon

Wrong. We are getting faster and shorter.

Will a Negative Leap Second Be Needed Soon?

Our planet is currently spinning, on average, ahead of schedule. This might lead to a negative leap second.

UPDATE (December 20, 2021): Shortest Year of Atomic-Clock Era

The average length of a day in 2021 has been 0.18 milliseconds less than 86,400 seconds (24 hours).

This daily difference has built up over the year, and Earth will complete its 365 rotations for 2021 about 65 milliseconds ahead of schedule. This will make it the shortest year since atomic-clock measurements began in the 1960s.

Global warming strikes again!

I haz love for global warming.
Especially 350+ miles west of the coast

Maybe in the short-term. However, long term geologically, Earth's rotation has been slowing down about 1.8ms every 100 years due to gravitational forces from the moon.

Ah, that explains why my sleep patterns are off. Gotta account for that fraction of a second every year now!
