What is time zone
A time zone is an area that uses the same standard time for legal, business, and social purposes. Time zones usually follow the borders between countries and their subdivisions. They don't always follow the lines of longitude. This is because it's easier for places that are always in touch to have the same time.
Each time zone is defined by a standard offset from Coordinated Universal Time (UTC). The offsets range from UTC−12:00 to UTC+14:00. Most of the time, the offset is a whole number of hours. However, some zones, like India and Nepal, have an additional 30 or 45 minutes. Some parts of a time zone may use a different time for part of the year. This is called daylight saving time (DST). During spring and summer, some areas use one hour more than normal.
How time zones developed
Before time zones, people used local solar time.This became awkward as railways and telecommunications improved because clocks differed between places by a amount corresponding to the difference in their geographical longitude, which was usually not convenient.This problem could be solved by synchronizing the clocks, but then local time would differ from the solar time people are accustomed to.Time zones are thus a compromise.There has been a trend to push the boundaries of time zones further west of their designated meridians to create a permanent daylight saving time effect.The increase in worldwide communication has increased the need for mutually comprehensible time references.
