Indian Standard Time

In 1906, in British India, all the railway and telegraph clocks were put at Indian Standard Time. Indiaimplemented their international standard time zone based on the 1905 decision for the Indian Time Meridian. It was set as the meridian passing through Allahabad at 82.5° east of the Greenwich Meridian longitude. The country had a single time zone, IST, at 5 hours and 30 minutes in advance of GMT. This was about 9 minutes faster than Madras time, and about 24 min slower than Calcutta time. (Railway Time had been in use since 1 Jan 1888 using Madras time.) However, Calcutta and adjoining areas, until 1948, kept a separate time zone, Calcutta LMT (Local Mean Time). Pakistan kept IST for three years after its partition, then in 1951 introduced Pakistan Standard Time at 5 hours ahead of GMT.«
