The '''Time and Frequency Standards Laboratory''' is a part of the [[National Physical Laboratory of India|National Physical Laboratory]] in [[New Delhi]] which maintains and calibrates the [[Indian Standard Time]].<br />
<br />
Features of the Time and Frequency Standards Lab include:<br />
* Four [[caesium]] and [[rubidium]] atomic clocks<br />
* HF broadcast service operating at 10&nbsp;MHz under call sign ''ATA'' to synchronise the user clock within a millisecond. This service has been discontinued as of today.{{when?|date=January 2019}}<br />
* An innovative time service via telephone line known as ''Teleclock'' service was launched on 28 July 2009.<ref>http://www.nplindia.org/launching-mobile-teleclock-0</ref> After successful commissioning this type of service in Nepal and Saudi Arabia, initiation of similar service in SAARC countries are being planned.<ref>http://www.nplindia.org/time-and-frequency-standards</ref><br />
* [[Indian National Satellite System|INSAT]] satellite-based standard time and frequency broadcast service which offers IST correct to ±10 microsecond and frequency calibration up to ±10-10.<br />
* Time and frequency calibrations are made with the help of pico- and nano-seconds time interval, frequency counters, and phase recorders.<br />
