The master clock in a clock network can receive accurate time in a number of ways: through the United States GPS satellite constellation, a Network Time Protocol server, the CDMA cellular phone network, a modem connection to a time source, or by listening to radio transmissions from WWV or WWVH, or a special signal from an upstream broadcast network.
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] For example, the Jantar Mantar observatory built by Maharaja Sawai Jai Singh in Jaipur in 1733 contains large sundials, up to 27 m (90 ft) high, which were used to accurately determine the local time.
