Who invented time?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C.

We learned that an analog clock is a clock with moving hands. If it has three moving hands, then we can tell the hours, the minutes, and the seconds. If it has two moving hands, then we can tell the hours and the minutes but not the seconds. To tell hours, we look at the shortest hand.
