Leap Second sync

A ‘leap second’ was added to the Indian clock at 5:29.59 hours on Sunday to synchronise with the Earth’s rotational clock. As the atomic clock at the National Physical Laboratory (NPL) here struck 23:59:59 last night, it was programmed to add an extra second to 2017 to compensate for a slowdown in the Earth’s rotation.

Adding a second barely has an impact on the daily life, but it does matter in the fields of satellite navigation,astronomy and communication.
