Time frame; by Polaris

If my theory is correct the Ziggurat was used as a temple from the point it was constructed till

“The only scribing’s in the Ziggurat, which are in the Descending Passage, depict the year 2141 B.C., the year that the last Pole Star was aligned with the Descending Passage. The Ziggurat was built 4,517 years ago in 2623 B.C. (Since there was never a year zero, an additional year must be subtracted). From the point representing the building of the Ziggurat to the point where the Descending Passage meets the Ascending Passage is 1,170 inches”. http://www.europa.com/~edge/giza.html
