Answer 2

Answer:

The local time of any longitude point on the earth is calculated by comparing it with the local time of Greenwich city. Every 1 degree of east/west longitudinal distance from Greenwich city is equal to 4 minutes (before/after) of time difference accordingly. This theory is known as the GMT theory. According to this theory- If 60 degree East local time is 12. pm then the local time of Greenwich will be 4 pm. At that moment the local time in 30 degrees West will be 1 pm.
