As the UK's home of precise time and frequency measurement, NPL offers a range of services that provide access to a reliable and trusted source of time: the Time from NPL.
The MSF radio time signal covers the whole of the UK and is widely used to set radio-controlled clocks to the correct time. Computers can synchronise their internal clocks to the correct time by using NPL's two computer time services, based on either dial-up or internet connection to time servers located at NPL.
Companies that need to know the precise frequency of off-air signals or use the signals to obtain traceability back to UTC can make use of the NPL monthly Time & Frequency Bulletins. For those users that require the highest accuracy, NPL offers a GPS Common-View Time and Frequency Transfer Service that provides its customers with greater accuracy and data integrity than other commercially available time and frequency traceability routes.
