How does london has time difference of 1 hour when it lies on the left of prime meridian?

Answer 1

Longitude is an imaginary line that runs from the North Pole to the South Pole and is used to describe the location of a place on Earth east or west of the zero or prime meridian. In 1884, the International Meridian Conference adopted the Greenwich Meridian as the universal prime meridian or zero point of longitude. Longitude is measured in degrees ranging from 0° at the Prime Meridian to +180° eastward and -180° westward. Each degree of longitude is further sub-divided into 60 minutes, each of which is further sub-divided into 60 seconds.
