Question

Option a: 06.30 hrs
Option b: 05.30 hrs
Option c: 18.30 hrs
Option d: 17.40 hrs

Answer 1

Hint: Standard time is the synchronization of tickers inside a geological zone or district to a solitary time standard, as opposed to utilising sun based time or a privately picked meridian (longitude) to set up a neighborhood mean time standard.

Complete answer: Indian Standard time (IST) is the time region noticed all through India, with a period balance of UTC+05:30. India doesn't notice light saving time or other occasional changes. Indian Standard Time is determined based on 82.5°E longitude which is located in the city of Mirzapur, Uttar Pradesh.India is a huge nation crossing over 30° of longitude. It is irregular in making some single memory zone everywhere in the nation, 5½ hours quickly. On the off chance that the bearing of pivot of earth is turned around, at that point Indian Standard Time will be – 5½ hr. At the point when it is early afternoon the time is 12:00; that will be 6:30 A.M. instead of 17:30 P.M. or on the other hand 5:30 P.M.

Option a is the correct option to the above question because 06.30 A.M. would be the Indian Standard time when it's noon at the International Date Line.

Note: Greenwich Mean Time (GMT) is regularly traded or mistaken for Coordinated Universal Time (UTC). Yet, GMT is a time region and UTC is a period standard. UTC isn't a time region, yet a period standard that is the reason for common time zones around the world.
