What is the time zone?
Because different countries and regions in the world have different longitudes and local time, they will be divided into different time zones.
The formal time zone division includes 24 time zones, and each time zone is represented by an English letter. Every longitude 15 minutes has a time zone, with one exception, and each time zone has a central meridian; For example, GMT belongs to the "Z" area, so the suffix "Z" is usually added after its time (the suffix "Zulu" is used in spoken language).
Origin of time zone:
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.
