Answer 2

Answer:

1. The local time of places which are on different meridians are bound to differ. For

example, it will be difficult to prepare a time-table for trains which cross several

longitudes.

2. In India, for instance, there will be a difference of about 1 hour and 45 minutes in the

local times of Dwarka in Gujarat and Dibrugarh in Assam.

3. It is, therefore, necessary to adopt the local time of some central meridian of a country as

them standard time for the country.
