Indian standard time

India does not observe daylight saving time or other seasonal adjustments. The Indian Standard Time was adopted on 1 January during the British era with the phasing out of its precursor Madras Time Railway Time , [2] and after Independence in , 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 and , respectively. Inhabitants of the northeastern states have to advance their clocks with the early sunrise to avoid the extra consumption of energy after daylight hours. In the late s, a team of researchers proposed separating the country into two or three time zones to conserve energy. The binary system that they suggested involved a return to British-era time zones, but the recommendations were not adopted. In , the government established a four-member committee under the Ministry of Science and Technology to examine the need for multiple time zones and daylight saving. Though the government has consistently refused to split the country into multiple time zones, provisions in labour laws such as the Plantations Labour Act, allow the union and state governments to define and set the local time for a particular industrial area. In , Chief Minister of Assam Tarun Gogoi started campaigning for another time zone for Assam and other northeastern states of India. Official time signals are generated by the Time and Frequency Standards Laboratory at the National Physical Laboratory in New Delhi , for both commercial and official use. The signals are based on atomic clocks and synchronised with the worldwide system of clocks that support Coordinated Universal Time.

Indian standard time

India does not currently observe daylight saving time DST or summer time. The official time signal is given by the Time and Frequency Standards Laboratory. The date and time notation in India shows some peculiarities. The 4th century CE astronomical treatise Surya Siddhanta postulated a spherical earth. The day used by ancient Indian astronomers began at sunrise at the prime meridian of Ujjain, [2] and was divided into smaller time units in the following manner: [3]. For most of India's history , ruling kingdoms kept their own local time, typically using the Hindu calendar in both lunar and solar units. In Madras Time was set up by John Goldingham [7] and this was later used widely by the railways in India. However, Calcutta Time was officially maintained as a separate time zone until and Bombay Time until In , time synchronisation began to be relayed through omnibus telephone systems and control circuits to organisations that needed to know the precise time. This continued until the s, when time signals began to be broadcast using the radio by the government.
