Extended data

In order to take care of the convenience of use in various regions and facilitate people from other places to take their local conversion of time to other places. The relevant international conference decided to divide the earth's surface from east to west along the meridian, and stipulated that the time difference between adjacent areas was 1 hour. People at the eastern and western ends of the same area can see the sunrise within 1 hour at most.

When people pass through an area, they will correct the clock to 1 hour (negative to the west 1 hour, positive to the east 1 hour), and when they pass through several areas, they will increase or decrease the hours. This is very convenient to use. Today, the world is divided into 24 time zones.

Because in practice, 1 country or 1 province often spans two or more time zones at the same time, 1 country or 1 province is often grouped together for administrative convenience. Therefore, the time zone is not strictly divided by the north-south straight line, but by natural conditions. For example, China is a vast country, spanning almost five time zones. However, for the sake of convenience and simplicity, in fact, only the time zone standard of Dongba is used, which is based on Beijing time.
