History of Time

The Egyptians and the Babylonians were among the first to develop methods to measure time.

The Egyptians used sundials and water clocks to measure time. The Babylonians on the otherhand were known for their sexagesimal (base-60) system. This system had a big influence on our current 60-second minute and 60-minute hour.

When the mechanical clocks were invented in the 14th century, tracking time became significantly easier. The accuracy of time tracking became even more precise when Christiaan Huygens invented the pendulum clock in the 17th century.

Time zones were invented to standardize time measurement across different regions of the world. Before the time zones, local mean time was used, which varied from town to town. When railroad system became more common, there was a need for more organised time-keeping system. Sir Sandfor Fleming proposed an idea of timezones in 1879. Global timezones were adopted five years later in 1884. The world was divided into 24 time zones. Each timezone covered 15 degrees of longitude.
