Now another scientific situation that lies ahead is that we will some day have to adjust to a 25 hour day due to the fact the moon is inching away from earth and causing a slight slow down in our rotation. However I wouldn't rush downtown to buy a 25 hour clock. Estimates are it will take ~ 200 million years to acquire thatg extra hour.
We are not even at a 24 hour rotation yet (3 minutes, 55.9 seconds short), the reason we perceive the day as 24 hours is because we are also orbiting the Sun and it takes slightly more than one rotation to get to the Sun to face the same point. If our orbit was in the other direction then it would be the opposite (i.e. Perceived to be shorter)
I believe the Moon acts the same as a figure skater.moving their arms in and out to vary their speed of rotation.
