Answer 2

The Egyptians invented the 24 hour day if that's what you mean.

When the sun went down they thought it had to go through the 12 gates of the underworld so they divided the night into 12 parts. Because the daylight was of equal length to the night they applied the same 12 divisions. Thus they divided the cycle into 24 which became our 24 hours.

The 24 hour clock would be a relativelt recent invention

Pendulum Clocks
Before pendulum clocks were invented, Peter Henlein of Germany invented a spring-powered clock around 1510. It was not very precise. The first clock with a minute hand was invented by Jost Burgi in 1577. It also had problems. The first practical clock was driven by a pendulum. It was developed by Christian Huygens around 1656. By 1600, the pendulum clock also had a minute hand The pendulum swings left and right, and as it swings, it turns a wheel with teeth (see the picture to the right). The turning wheel turns the hour and minute hands on the clock. On the first pendulum clocks, the pendulum used to swing a lot (about 50 degrees). As pendulum clocks were improved, the pendulum swung a lot less (about 10 to 15 degrees). One problem with pendulum clocks is that they stopped running after a while and had to be restarted. The first pendulum clock with external batteries was developed around 1840. By 1906, the batteries were inside the clock.
