in our country .82°30`E is the central Meridian. it passes through a place near Allahabad .it is known as Standard Meridian of India. while fixing the Indian standard time with respect to the Greenwich mean time ,we have to add 82° 30` × 4 minutes=330 minutes or 5 1/2 hours. this mean that India is 5 1/2 hours ahead of GMT. thus if it is 9 A.M at London it must be 9 + 5.30 or 1 4.30 hours or 2.30 pm in India.
