What is Time Zone? Time zones are the only way to decide on the date and time for the countries of the world. In order to precisely measure and use time, everyone in the world would like to decide on the noon as the time at which the sun is at its highest point in the sky or when it crosses the meridian. This is impossible without knowing the time zones. As the earth rotates at 15 degrees every hour, the sun is at its highest point in the sky at different times in the day for different countries around the globe.
