Geography - Local and Standard Time
Relation of Time and Longitude :
Time and longitude are related. As the earth rotates, every place experiences the phenomena of sunrise, noon and sunset. One hour of time is equivalent to 15° of longitude. This can be calculated and understood from the fact that the earth completes one rotation on its axis in 24 hours, so in each hour , it covers 15° of longitude to cover 360°of longitude in total.This also means that 1° of longitude is covered every 4 minutes during the daily rotation of the Earth. This equality forms the basis of all calculations concerning time belts of the globe.
