    The time it takes for the Earth to perform one rotation on its axis has been growing (1.7 ms per century). This is caused by ocean tides generated by both the moon and sun's gravity. 350 million years ago, in the early Carboniferous period, a day was less than 23 hours longpic.twitter.com/BixfyZPofk

        The tides are a consequence of a difference in force across the radius of earth. The near side of the earth to the moon is an earth radius closer to the moon than the center is. The far side is an earth radius *farther* than the center, so there’s a difference between both sides.

        yeah, but I would still reset my clock each week using a 24 hour period. Maybe that way I could get to the meetings on time.

        This means the speed by which we're growing older is slowing down. :) But probably not fast enough :(
