Why is standard time neded for very country ?
Answers
Every country need standard time because there is different time in different states to avoid the confusion of time between different states all the countries adopted a standard meridian to found same time for a country. India adopted a standard meridian which is 82°30' E which passes through Mirzapur in Uttarpradesh.
Answer:
It is basically to avoid confusion. If we had only 1 time eg: GMT then the principal that AM refers to morning and PM refers to night wouldn't apply. In that case you cannot differentiate food, sleep timings when you travel. The entire world will be confused when communicating since you don't know what time it in the other country ie day or night. Work and school timings start usually at 8:00am (white companies) but i am having midnight 8:00am while you have morning 8:00am which causes confusion to human brain or a common individual..
