Hey
Here is your answer,
✔The Earth has been divided into 24 time zones of one hour each. Each of these zones covers 15 degrees of longitude.
✔As the local time differs by 4 minutes at every longitude, it would create a lot of confusion regarding time for any country as a whole which may stretch across several longitudes.
✔Therefore each country selects a central meridian and the local time of this meridian is the standard time of that country.
✔The local times which lie on different meridians are bound to differ.
✔The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat.
✔This causes a time lag of 2 hrs from Gujarat to Arunachal Pradesh to avoid confusion and to have a standard time for reference, The 82.30'Eastern Longitude has been taken as the standard time for the whole country.
✔The local time at this Meridian has been accepted as the Indian Standard Time (IST) throughout the country because it passes through the middle of the country.
✔It has helped to avoid a lot of confusion which would have been there by following different local times or in absence of a uniform time.
Hope it helps you!
