The time signal which sets the nation's clocks is to break with almost 80 years of tradition by moving away from Rugby.
The radio message, which is used to provide timings for everything from the 999 emergency services to the BBC's famous pips, will move to a new home next year.
The service, which is run by the National Physical Laboratory (NPL) will be moved from Rugby - its home since 1927 - to Anthorn, west Cumbria.
Atomic clocks based in Teddington, south-west London are used to keep the time accurate to within one milli-second, which is 1,000th of a second.
Bosses at NPL decided to switch contracts from BT, which owns the site at Rugby, to VT Communications, which runs the Anthorn complex.
The signal, often referred to as "The time from Rugby", will in future be known as "The Time from NPL".
NPL has been responsible for keeping the time signal accurate from Rugby since 1950 and will make the switch to the new venue in April next year. The switchover will take place following a three-month test period and NPL stressed most users need take no action to continue receiving the signal.
NPL managing director Steve McQuillan said: "Maintaining accurate time is essential to keeping the modern world working.
"Most people only need time to be accurate to within a few seconds or even minutes, but global navigation systems, the internet, email, television, power industry, transport, and financial systems are just some of the industries that depend on very accurate time to operate."
