The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west, but the watches show the same time. How does this happen?

Answer
The latitudinal and longitudinal extent of India is about 30°. The east-west extent is smaller than the north-south extent. There is a time lag of two hours from Gujarat to Arunachal Pradesh. As Arunachal Pradesh lies on the eastern side of India, the sun rises here earlier when compared to Gujarat. The time along the Standard Meridian of India (82°30’E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country. The latitudinal extent influences the duration of day and night as one moves from south to north. Therefore, the watches show the same time in all parts of the country.
