The national Physical Laboratory (NPL) is the Uk's home of measurement and the nation's timekeeper. NPL is responsible for operating the national time system and making accurate time available across the UK. The clock you are looking at keeps accurate time by picking up NPL'S radio signal, called MSF, which is broadcast on 60 khz from a location in Cumbria.

This transmission carries a date and time code that radio controlled clocks use to set themselves to the correct time. The signal is controlled by atomic clocks at the radio station, and is adjusted to keep it in step with the national time maintained at NPL's laboratory in south-west London. For more information visit www.npl.co.uk/time

Your clock is controlled by the MSF signal which is synchronised to the national time scale at NPL, making it 'forever accurate'
