'Oracle Bones' Testify To an Ancient Eclipse

A team of historians and astrophysicists has concluded from cryptic inscriptions on an ancient fragment of tortoise shell that 33 centuries ago the length of a day was about one-twentieth of a second shorter than it is now.
This fresh evidence that the earth spins more slowly as the centuries pass was inferred from an inscription in early Chinese meaning: ''Three flames ate the sun, and big stars were seen.'' From this and a chain of other clues, the scholars deduced that a Chinese seer of the Shang Dynasty had unwittingly bequeathed some important scientific information.

Title: Basic Mechanics of Planet-Satellite Interaction with special reference to Earth-Moon System
Authors: Bijay Kumar Sharma

In 18th Century, German Philosopher Kant had suggested the theory of retardation of Earth's spin based on the ancient records of Solar Eclipses [Stephenson 1986, Stephenson 2003]. Similar kind of studies have been carried out by Kevin Pang at Jet propulsion Laboratory at Pasadena [Morrison 1978, Jong & Soldt 1989]. He happened to step upon certain ancient records regarding Solar Eclipses. A total Solar Eclipse had been observed in the town of Anyang, In Eastern China, on June 5, 1302 B.C. during the reign of Wu Ding. Had Earth maintained the present rate of spin, the Eclipse should have been observed in middle of Europe. This implies that in 1302 B.C. i.e. 3,291 years ago Earth's spin period was shorter by 0.047 seconds. This leads to a slowdown rate of 1.428 seconds per 100,000 years.
