Answer 1

In my point of view , I think Indian needs to have more than one standard time because India has a large longitudinal extent of about 30°.

1. When the sun is still shining in western coast it is already night in northeast so we need two or more time zones to clearly reflect day to day changes.

2. Time variation of 2 hours between Easternmost & the westernmost parts of our country. The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat because the earth is tilted and also it rotates in East to West direction so during rotation the Eastern part of the world experiences that sun rays earlier as compared to the western parts of the world.

3. In other countries like USA , Canada & Russia have more than one standard time because their longitudinal extent is large. India longitudinal extent is also 30°. Therefore it is advisable to use more than one Standard Time.

Answer 2

Yes, because there is a time gap of about 2 hours between the easternmost parts to westernmost parts of the country. The longitudinal extent of India is large i.e., 30° approximately. Therefore, we need to more than one time zones.
