Question

the sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the West but the clocks show the same time how does this happen

Answer 1

The longitudinal gap between Arunachal Pradesh and Gujarat is about 30°. Due to this, there is time lag of about two hours between these states. Since Arunachal Pradesh is in the east hence the sun rises earlier here; compared to in Gujarat. The Indian Standard Time is taken from the time of Standard Meridian of India and hence the watches show the same time in both the states.

Answer 2

Although the sun rises two hours earlier in Arunachal Pradesh as compared to Gujrat in the west the clock shows the same time because all of our clocks follow a time meredian, known as the IST or Indian standard time.

We follow this to have a uniform time all over India and if we have to attend a meeting in Gujrat and come from Arunachal Pradesh we won't miss it.

Now, we don't follow the time that we used to follow using a sun dial
