Leap Second added to Indian Clock to Synchronize with Earth’s Spin

Leap Second added to Indian Clock to Synchronize with Earth’s Spin An extra second was added to the Indian clock at 5:29.59 hours at the National Physical Laboratory (NPL) on January 1, 2017 as the atomic clock was struck at 23:59:59 the previous night. The ‘leap second’ was added to the Indian clock to synchronize the Indian Standard Time (IST) with the Earth’s Rotational Clock. The atomic

clock was programmed to add an extra second to 2017 to compensate for a slowdown in the Earth’s rotation. Addition of the leap second to the Indian clock is done by the NPL under the Council for Scientific and Industrial Research. The NPL, one of the oldest laboratories in the country, has five atomic clocks and nearly 300 such pieces exist across the globe.
