So Long, CHU, And Thanks For All The Time Signals

In the long ago, pre-internet days when your clock project wasn’t an ESP32 getting its timing via NTP over WiFi, it was still possible to build a wirelessly-updating clock. All you needed was…

Hackaday
Moved the #RadioClock to a 3rd location at the north side of the house upstairs, battery out and in, and this time it's picked up the signal and corrected itself, thankfully.
My radio wave #clock hasn't changed the time this morning (BST). I put a fresh battery in and it's reset to 12:00:00. Sat like that for 10 minutes, now the hands are moving at normal speed, so it's now showing 11 minutes past 12 rather than 23 past 7 am. I'm guessing it's due to the Rugby #RadioClock being turned off and replaced by Cumbria? Moved the clock upstairs for better signal, still no joy.
How does Britain know what time it is?
