Question

On what basis do we measure time?​

Answer 1

Explanation:

The measurement of time of day can be traced back to the Egyptians and Babylonians, who used sundials to approximate the time of day and the movement of celestial bodies to identify changing seasons. In effect, the rate of the earth's rotation was the standard against which they devised a timescale.
