Method for calculating time zone

Calculated time zone = known time zone-(time zone of known time zone-time zone of time zone to be calculated), (Note: the eastern time zone is positive and the western time zone is negative).

For example, it is known that the time in Angola (East District 1) is 1 May 12:00, and the district of Beijing (East District 8) is found.

Beijing time =12: 00-(1-8) = 19:00 (that is, Beijing time is May 019: 00).

Then the time difference between Angola and Beijing is 7 hours, and Angola is 7 hours later than Beijing.

Extended data:

With the rotation of the earth, the sun rises in the east and sets in the west in a day. When the sun passes the highest point in the sky, the local time is 12. Therefore, different meridians have different local time.

The same time used in the same time zone is the time zone (local time on the central meridian of this area), and the same time used around the world is universal time (local time on the meridian of 0 degrees). Local longitude distance 15 degree for one hour, local longitude distance 1 degree for four minutes.

The standard time everywhere is Greenwich Mean Time plus (+) or minus (-) the time difference between hours and minutes in the time zone. Many countries also adopt daylight saving time (DST). For example, the United States implements DST from April to September every year, one hour in advance.
