100-year history changes the time of the season

The clock is tuned faster to take advantage of summer sunlight in European and American countries and adjusted in winter, rooted 100 years ago.

According to the Telegraph, this idea was initiated by Benjamin Franklin, an American inventor and politician. During his time as US ambassador to France, he wrote an essay "Economic project to reduce light costs" for the Paris Journal in 1874.

In this essay, he thinks that Parisians can reduce the time to use candles by getting up earlier in the morning, taking advantage of daylight to work.

William Willett introduced the idea of summer time (DST) in the UK in 1907. He published his book "Daytime Waste" in an effort to mobilize people to get up early by changing copper. National lake.

Willett suggested 8 times of change in one year, 4 times of 20 minutes on every Sunday of April, and 4 times of the opposite of every Sunday of September. A total of 80 minutes of quick and slow adjustments.

However, Willett later became ill and died in 1915, a year before Germany adopted his idea of ​​changing his time on April 30, 1916. He later applied the time shift from May 21, 1916, nearly 100 years ago.

This was the period of World War I (1914-1918), when Britain and Germany were on both sides of the front line. A proposal could alleviate the pressure on the economy, reduce domestic coal consumption, increase supply for production activities and such war is worth testing.

The timing on the mechanical clock at the time was a bit of a problem, as it was impossible to turn the clock backwards without damaging the mechanical system. At the end of the daylight time (DST), you have to adjust the time by quickly turning 11 hours.

To commemorate Willett, a sundial near Petts Wood, a southeastern London suburb, was named after him. There is also a road called Willet Road.

Today, DST is agreed for one hour. European Union member countries exchange DST synchronous hours including Britain, France, Germany, Spain, Italy and Bulgaria, along with most other European countries, such as Norway and Switzerland. Some other countries, including Russia, Iceland, Georgia, Armenia and Belarus do not change hours.

In the United States, most states start DST at 2 am on February 13. Applying DST today brings benefits such as energy saving, reduced traffic accidents, promoting tourism and encouraging people to get out of the gym.
