Celestial Mechanics

For the first time in three years
Official clocks will pause for Earth's rotation
To realign with atomic time

Fluctuation is due to Earth's interaction with the Moon
Primarily tidal acceleration
This process, this effect of tidal force
Slows our planet's rotation

Angular momentum, in direct correspondence
With Earth's axial tilt is dampened
An existing kinetic energy
Within orbit is lessened

All the same, the reduction is notably fractional
Specifically, days on Earth grow 1. 4 milliseconds
Longer every one hundred years
To put that in a different perspective

It won't be for another 100, 000 years
Until each day is about one
And a half seconds longer than
As they exist today
