For instance, China follows only one time zone instead of three standard time zones. They continue to use their times until today.

As a result, they have created the standard time to divide the Earth into 24 sections or time zones.Įvery time zone is 15 degrees of longitude wide. In the 1800s, scientists used a new system for time zones based on the degrees of rotation and longitude. Many time zones were created before, confusing travelers about the time. Without it, noontime will be morning or even evening in other places. The Earth’s rotation is the primary cause why countries follow different time zones.

As the planet rotates, some places receive sunlight or darkness, resulting in day and night.
