The time remains same in two places because of IST line

But in Arunachal Pradesh is at the east of India sun rises early

and in Gujarat is at the west of India so the sun rises lately

Answer 2

$\huge\mathfrak\green{answer!}$

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 to 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 Mirzapu 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 the parts of the country.
