Clocks have been around almost for since the dawn of time. It seems like these wonderful time keeping machines have been around for such a long time, but the first clocks appeared around the earth 5,500 years ago. The first versions were the well known sun dials, and these time keepers were used when the sun’s shadow would be projected down onto a flat base of stone, and a projecting arm would cause the shadow to fall on to the designated hour of time. For obvious reasons, these clocks only worked well during the day.

Before that, the sun’s position in the sky was used as a means to keep track of time. After that, Egyptians and Greeks used water dials to figure out what time it was. The Greeks worked on developing a time system, dividing up time into years, months, weeks, days, hours, minutes, seconds. From there, the history of clocks was changed, and people began to improve clocks. Before the pendulum clock, there were spring powered clocks. These were not very affective and did not catch on as well.

Clocks then started getting a minute hand, and after awhile, pendulum clocks ended up with a minute hand as well. It was soon after that pendulum clocks took on the full effect, with popular varieties such as the still popular grandfather clock. As the pendulum swings, teeth on a gear rotate, changing the gears and the hands on the clock. By 1906, these clocks had batteries, and were powered externally beforehand.


Because of the advances in time keeping, in 1884, people met from around the world and started to invent the time zones. This meant that international clocks and other kinds of time keeping can be perfected and restored to a level that would work for people worried about international time. It helped countries further develop train and bus schedules, so that people on the other side of the country or a state would not be confused by someone’s time. Since then, time keeping and clocks have advanced to include things like digital clocks and wall clocks like analog clocks. Even today, clock making and clocks go even further into the future.

Water clocks came into the picture about 1400 BC. It was soon discovered that Water Clocks were better than the sundial but still did not keep good time. About 1577 the minute hand was added. Until the pendulum clock was developed in 1656 by Christiaan Huygens, and then by 1700 when a secondhand was added to the pendulum clock did the clock become more accurate. The pendulum clock was accurate within a minute versus the earlier spring driven clocks only being accurate within 15 minutes. For the times that was good but to be within a minute they are moving forward.

Due to the difficulty in keeping these clocks going, about 1840 an external battery was added. It was actually the British Parliament offered a reward for the individual whom would be able to solve the problem of the lack of accuracy in the pendulum clocks. There were many theories by John Harrison won the prize. Many advances were being made towards mass production. Clocks soon became a common place due to prices coming down. My great-grandmother gave my great-grandfather a pocket watch for a wedding present. That pocket watch was made of solid gold with a beautiful design.

In the late 1800’s, people were meeting from around the world to start inventing the time zones. Having time zones you would be able to use international clocks and other kinds of time keeping would be perfected to work with international time. Now countries could develop bus and train schedules so that people to get from one end of the country to the other.
