The leap second adjustment (which is approximately 0.6 seconds per year) should not be confused with the difference between the length of the mean solar day and the SI day. This confuses velocity with travelled distance (in time). The reason for leap seconds is not the difference but the sum of the difference between the SI day and the mean solar day (currently about 0.002 seconds) over a given period of time. The actual rotational period varies due to unpredictable factors such as the motion of mass within Earth, and has to be observed rather than computed
http://en.wikipedia.org/wiki/Leap_secondmy thoughts:
the rotation of the earth is slowing down, making the 24-hour-day longer
the slowing is about 0.6 second per year,,,,,,,,,which is = 166 hours per million years.............so, 1 million years ago, the 24-hour-day was ..........166 hours.........SHORTER..............
the days are longer NOW than millions of years ago...........
in every school text book in the world (except the christian text books),,,,,,,,,,,,it says,,,,,,,,,,millions of years ago,,,,the dinosaurs lived millions of years BEFORE man ever existed
every evolutionist and teacher knows that the earth's rotation proves evolution wrong,,,,,,,,but, they keep it a secret from us,,,,,,,,,,they are deliberately trying to destroy our faith in the bible
the circumference of the earth = 25,000 miles at the equater,,,,,,,,,,the earth rotates every 24 hours,,,,,,,,,,so a spot on the equater is traveling 25,000 miles per 24 hours..........or about 1000 miles per hour
a million years ago, the earth would have rotated at the speed of:
the calculation is impossible............you can't subtract 166 hours from 24 hours
evolution is a lie
