Something i Came Across About the Age of the Earth

[Bono]

I came across this:

[font=trebuchet ms,arial,helvetica]Consider two methods of estimating the age of some fossils which gave the same approximate result: [/font]

[font=trebuchet ms,arial,helvetica] Scientists note that the world's rotational speed is gradually slowing down, because of frictional losses produced by the oceans' tides. Clocks are set ahead by one "leap second" -- usually at the end of some years -- in order to compensate for the slowing of the earth. Some fossils of rugose corals have been found which show both daily and yearly growth patterns. They indicate that when the coral was alive, there were about 400 days in the year; i.e. each day was about 22 hours long. Scientists assume that the rate of slowing of the earth's rotation is more or less constant; there really is no obvious way in which the deceleration rate can change. They can estimate that about 350 to 400 million years ago, the day would have been only about 22 hours long. Thus, the corals are approximately of that age.

Does anyone know a good creation science to this, and if possible a link?
