The Surya Siddhanta also described a method of converting local time to the standard time of Ujjain. [5] Despite these early advances, standard time was not widely used outside astronomy. For most of India's history, ruling kingdoms kept their own local time, typically using the Hindu calendar in both lunar and solar units. [6]
The Indian Standard Time was adopted on 1 January 1906 during the British era with the phasing out of its precursor Madras Time (Railway Time), [2] and after Independence in 1947, the Union government established IST as the official time for the whole country, although Kolkata and Mumbai retained their own local time (known as Calcutta Time and Bombay Time) until 1948 and 1955, respectively.

The main purpose of this page is to list the current standard time offsets of different countries, territories and regions. Information on daylight saving time or historical changes in offsets can be found in the individual offset articles (e.g. UTC+01:00) or the country-specific time articles (e.g. Time in Russia).
It was then decided that India would have two time zones, Calcutta (now Kolkata), and Bombay (now Mumbai). Bombay Time was set at 4 hours and 51 minutes ahead of Greenwich Mean Time (GMT). [1] [2] However, Bombay Time was difficult to convert to Indian Standard Time (IST) after it was adopted on 1 January 1906 as the official time zone of India.

The International Time Bureau (BIH) began a time scale, T m or AM, in July 1955, using both local caesium clocks and comparisons to distant clocks using the phase of VLF radio signals. The BIH scale, A.1, and NBS-A were defined by an epoch at the beginning of 1958 [ a ] The procedures used by the BIH evolved, and the name for the time scale ...
