World Clock Time Zones
A time zone is a region of the earth that has uniform standard time, usually referred to as the local time. Time zones compute their local time as an offset from UTC (also refered as Greenwich Mean Time). Local time is UTC plus or minus the current time zone offset for the considered location.
Some countries have more than one time zone depending on the size and location of the country. Country like France with it's terrieries spread aground the globle has 12 time zones. US and Russia for its size has 11 and 9 time zones respectively.
The use of local time zone is needed for easy of railways and telecommunication. Geographically countries or territories located in the same longitude has the same UTC offset or same time zone.
