Question

Why it is necessary to have standard time for every country?

Answer 1

Answer:

Explanation:

Time zones depend on longitudes

Some countries are big hence have more thn 1 longitude while the small countries wil only hv 1 longitude

So there is a requirement for standard time by which we cn calculate the time zone or u could say time  of any country or places within the country

Answer 2

Answer:

As the local time varies from place to place, it would create confusion if each people were to follow its own local time. The preparation of timetables for railways, buses,etc., would be difficult. Also, people travelling from one place to another should adjust their watch according to the local time at those places. In order to avoid such confusion, most countries follow uniform time throughout the country.
