Antediluvian Kings of Babylon - Cunieform records indicate these kings rules for 432,000 years.
Mesopotamian Time - Our system of 24 hours with 60 minutes to the hour and 60 seconds to the minute originated in Mesopotamia.
Chinese Time - The Chinese viewed the year on a lunar basis and created a 12 year cycle associated with 12 different animals. The Chinese divided the day into 12 segments of 2 hours each. Each segment was defined by one of the 12 animals from the annual cycle.
Indian Time - In India the cycle of time was calculated on a 5 year cycle of 60 months.
Cambodian Annual Cycle - The Cambodians adopted the 12 year animal cycle from the Chinese but created another cycle of 10 years to form a pattern that did not repeat for 60 years. For example, the tiger (the Chinese animal for 1998) would be combined with the first of 10 years and then the next animal next year and so on. Finally, the tenth animal would be combined with the tenth year and the eleventh animal with the first of the next 10 years and so on. After a total of 60 years, we would be back to the Tiger and the first of the 10 years again. Both the Chinese calendar and the basis for the Indian calendar would come into perfect conjunction every 60 years in Cambodia.
The Khmer recorded time is a measurement known as "saka". For example, inscriptions indicate that the king who constructed Angkor Wat was installed as king in 1035 saka. This translates into A.D. 1113. There are a series of dates inscribed in the third gallery that cluster around this date when the king took the thrown. It is likely that the king was born on 1021 saka (A.D. 1099). He would have been around 17 or 28 years of age in 1048 saka (A.D. 1126), and 31 or 32 in A.D. 1131, a date recorded at Angkor Wat.
Suryavarman II - King who built Angkor Wat.
In 1123 and 1124 A.D. friction between the Khmer and Chams led to fighting.
In A.D. 1128, the Khmer king reportedly sent 20,000 men against the Dai Viet in northern Vietnam and lost the battle. In the fall of the next year he sent a naval force out and again was defeated. In 1130, he launched another major effort against the Dai Viet that too ended in defeat. He enlisted the help of a people known as the Cham and in A.D. 1132 once again attacked the Dai Viet with the same result. Four years later he again attacked the Dai Viet and lost once again.
