Time is Gold every days value is as good as gold is produced.
Because of the high value of the time, the slaves themselves had to hurry to dig even faster. 
Extracting Gold from the mines was in the days of ancient Babylon, ruled by the Sumerians and visited and supervised by the Gods, who lived on a planet in our solar system, the most important.
New ships and cities in the sky were necessary for the gods.
Then the gods sent the Annunakis down to us to extract minerals from the earth.
For work, they used the people of the ancient Babylon.
Every minute were counted in units of gold.
So they need a clock to take the control of the work.
These gods knew how to fly with their ships. The eagle was the symbol; that shows the power of flight.
