Here is one item I have found in my resources that might be of interest.
Atomic clocks, which have for the last 22 years measured the earth's spin rate to the nearest billionth of a second, have consistently found that the earth is slowing down at a rate of almost one second a year. If the earth were billions of years old, its initial spin rate would have been fantastically rapid--so rapid that major distortion in the shape of the earth would have occurred. a) Arthur Fisher, "The Riddle of the leap Second," Popular Science, Vol. 202, March, 1973, pp. 110-113, 164-166. b) Air Force Cambridge Research Laboratory, Earth Motions and Their Effect on Air Force Systems, November 1975, p. 6. c) Jack Fincher, "And Now, Atomic Clocks," Readers' Digest, Vol. III, November 1977, p. 34.
Also a link which I'm sure may spark a bit of controversy since it is from a Creation Science Research site. It tells what I have heard elsewhere. I will attempt to find the information in another source which which you will be more confident in.
