Do we need more than one ist If yes explain why?
Countries across the world keep different times because of Earth’s rotation and revolution around the Sun. As Earth turns by 15° around its axis, time changes by one hour; a 360º-degree rotation yields 24 hours. As a result, the world is divided into 24 time zones shifted by one hour each.
Why India has a standard time?
India’s single time zone is a legacy of British rule, and is thought of as a symbol of unity. … India stretches 3,000km (1,864 miles) from east to west, spanning roughly 30 degrees longitude. This corresponds with a two-hour difference in mean solar times – the passage of time based on the position of the sun in the sky.
Why did some countries have more than one standard time?
Some countries have a great longitudinal extent i.e. large geographical extent due to which they have large time difference between there East and West extremes.So they have to adopt more than one standard time.
Does India need multiple standard time?
Now to answer the question Yes, India requires multiple standard times due to a time difference of around 2 hours between the easternmost and westernmost portions of the country. India’s huge longitudinal expanse is estimated to be around 30 degrees.
Does India need multiple time zones?
India is geographically the second-largest country not to have multiple time-zones India stretches from 97 degree 25 minute East in Arunachal to 68 degree 7 minute East in Gujarat — almost 30 degrees of longitude which is more than enough to have two time-zones.
Why is standard time necessary?
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.
What is the advantage of having one Indian Standard Time?
Answer: The main advantages of standard time are: The local time can be confusing if all the places on the earth use their own local time. The smooth functioning of railways, airways and other means of transport and communication would be disrupted.
Why is Indian Standard Time half an hour off?
When the meridians for the Indian subcontinent were created, New Delhi was in between the two. Naturally, India decided to be 30 minutes between the two time zones, which is why the country is only 30 minutes ahead of nearby Pakistan, for example.
Why is it necessary for some countries to have more than one time zone class 6?
Some of the countries are so big, i.e. they cover a land area, so large, that more than one set of 15 degrees of longitudes intersect the country, thus resulting in two or three or more time zones in that country. This is why some countries have more than one time zones.
Which country has multiple standard time?
Russia: The only country in the world that has all its time zones over the mainland is Russia. Once the biggest country in the world, Russia has 11 time zones.
