Question

Does India need to have more than one Standard Time?

Answer 1

Hint: For legal, commercial, and social purposes, a time zone is a region that observes a uniform standard time. Because it is more practical for locations in frequent communication to preserve the same time, time zones tend to follow the borders of countries and their subdivisions rather than rigidly following longitude.

Complete answer:
From UTC-12:00 to UTC+14:00, all time zones are defined as offsets from Coordinated Universal Time (UTC). The offsets are normally a whole number of hours, however, some zones, such as India and Nepal, are offset by an additional 30 or 45 minutes. The Republic of India employs only one time zone, termed Indian Standard Time (IST), which is five and a half hours ahead of Coordinated Universal Time (UTC).

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. As a result, even when the sun is blazing brightly on the west coast, it is already dark in the northeast. As a result, two or three time zones are required to accurately reflect diurnal fluctuations. Because of their great east-west extent, a country like the United States has seven time zones.

Note: Some countries, like China and India, employ a single time zone despite the fact that their land greatly exceeds the optimal 15° of longitude for one hour; others, like Spain and Argentina, utilise normal hour-based offsets, although not necessarily those specified by their physical position.
