Question

why is it necessary to have Standard Time ​

Answer 1

The time of a place depends on the longitude that passes through it. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it. India has a vast longitudinal extent. Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country. Thus, we need a standard meridian for the country.

In India 82 ½ °E longitude determines the standard time. This is known as the Indian Standard Time. This longitude passes through Allahabad in Uttar Pradesh.

Answer 2

Answer:

Explanation:

It  can be understood by the following points:-

1. To make a time table for trains and flights time zones play a

crucial role. As different time zone have different time

therefore it becomes difficult to make a time table without a

standard time.

2. Standard time also helps to keep the uniformity of the time

throughout the country.

IST or Indian Standard Time- Longitude of 82°30’E is

demeaned as the standard meridian. The standard time of

India is taken from this meridian.
