Living with one time zone across India

Why the half hour
82.5°east, the meridian India's clock follows
Indian Standard Time is set by the 82.5° east meridian. That line runs near Mirzapur in Uttar Pradesh, close to the middle of the country. It falls between two whole-hour zones, which puts India's clock on the half hour. CSIR-National Physical Laboratory in New Delhi keeps the official time with atomic clocks.

The northeast
2 hnearly, between sunrise in the far east and the far west at the equinoxes
Around the equinoxes, the sun rises almost two hours earlier in Arunachal Pradesh than in Gujarat. So in the northeast, much of the morning has gone before offices open. Scientists at the National Physical Laboratory have proposed a second zone for the region. The government has kept one zone, citing strategic reasons.

+1 hahead of IST, an informal clock
Many tea estates in Assam keep their own informal clock, known as tea garden time or bagan time. It runs one hour ahead of Indian Standard Time, so that work follows the daylight. Government offices and official timetables in Assam run on IST.

The Andaman and Nicobar Islands
ISTlike the mainland, far to the east
The islands lie far to the east, in the Bay of Bengal. Yet they keep Indian Standard Time, like the mainland. By the clock, the sun rises and sets there much earlier than in Delhi.
