Coordinated Universal Time
Around the world people need to keep to an agreed timescale.
The time measured by the rotation of the Earth about its axis
slowly drifts away from UTC this means leap seconds are inserted in order,
to keep UTC to within 0.9 seconds of the Earth's time.

Atomic time and UTC are kept through the collection of about forty laboratories
worldwide, each labratory housing several atomic clocks. The National Physical Laboratory
collaborates on behalf of the UK and it has the responsibility for maintaining the
national scale of UTC. The National Physical Laboratory broadcasts time signals from a transmitter at Rugby.
Anyone with a suitable receiver can set their clock directly against the national atomic clock.
Some clocks used for domestic every day use are now available with an in-built receiver.
