No one invented time; it was likely discovered, even if subconsciously, by every culture.
At some point early on, humans were aware of time passing and began keeping track of it. Although we don’t know who was the first, archaeologists are discovering more and more ancient civilizations that devised their own unique ways of marking time.
Stonehenge is an example. The earliest clocka shadow clock similar to a sundialcan be dated all the way back to 3500 B.C., and the hourglass came into being not long after. Over time, humans invented the mechanical clock, then the pendulum clock.
Today we use a twenty-four-hour clock and have the world divided into time zones. The zones start at zero at the original site of the Greenwich Observatory in Greenwich, England.
We go by what is called the Scientific Standard of Time, based on the second, which is defined by scientists as “the duration of 9,192,631,770 periods of radiation,” and in other circles as “one Mississippi.”
