Calcutta time
From Wikipedia, the free encyclopedia
Calcutta time was one of the two time zones established in British India in 1884. It was established during the International Meridian Conference held at Washington, D.C in the United States. It was then decided that India were to have two time zones, with Calcutta (now Kolkata) would use the 90th meridian east and Bombay (Mumbai) the 75th meridian east. Calcutta time was set at 5 hours, 30 minutes, and 21 seconds in advance of GMT.
It remained in effect even after Indian Standard Time (IST) was adopted on January 1, 1906. In 1948, Calcutta time was completely abandoned in favour of IST.
