Which large country uses UTC +5:30 time zone?
China
Iran
India
Brazil
India is one of the few countries that use single time zone with a 30-minute increment from UTC. The country's east–west distance covers 28 degrees of longitude, resulting in two hours difference in astronomical time. Since authorities decided to have one time zone for the whole country, they had to adjust it precisely.
