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
