How does Britain know what time it is?

My Casio G-Shock watch picks up this radio signal (or one of five others round the world) and is solar powered, so in theory will be charged and accurate for decades to come.

Although I have several clocks that are auto set, I really don't need them, my cat knows exactly when 7AM and 7PM are, 'cause that is meal time! The rest of the day doesn't matter, so I don't care anyway.

Saw this in my recommended and thought it was a new upload but it turns out it’s just from my watch later list 😔

I am surprised that given the simplicity of this technology, my Sony radio alarm clock (which has an actual tune-able FM radio built in, for crying out loud!) lacks this feature. It has drifted about 8 minutes in 3 years.

The Transmission Station used to be near to Rugby and I got an update signal just fine
... now the Station is in Cumbria ... no updates received in the Midlands 😢

How does the Germany know?

The Radio Controlled clocks I had have never worked.

If I go to the moon , and when England is below me I look through binoculars at a clock at the transmitter site , it says midday.
Then I peer at a clock in London it appears to be slow, by about 100 microseconds .
So is the term universal time not quite right?

Why does my radio controlled clock lose two hours every month or so, then automatically right itself a few hours later?

Interesting but the cable management at NPL is worst than in my office at home, kind of worrisome

Very interesting and informative- thank you.

Used to be based in Rugby didn't it?
They were always called Rugby Receivers on the clock boxes from what I remember?

I was once told that Rugby Radio station transmitted this time signal? Did it? (it's not there any more)

"Not enough power"? It's a receiver! 🤣

Odd that scientists cannot say for definite that time does or does not exist. Did man create time or were we given time ?

All those wires hanging around there are the result of extreme frustration.
If you can't fix it, wire around it. Age old concept. 🎉

We had one of these clocks in primary school Year 5 (United States 6th Grade). I found it quite remarkable.

We'd always see it turning clockwise and anticlockwise really fast. It must have been confused.

My OCD is kicking in. That desperately needs some cable management.

Is it available on St. Helena?

Because we decided what time it is/was/will be.

Britain watches Dave Allen's hilarious sketch "Telling the time"

What's with the French stuff?

It's CUT (Coordinated Universal Time) not UTC (Universal Time Coordinated).

We are not French, we invented the measurment of time, why does our establishment allow the French to lay claim to our stuff? What is wrong with them that they constantly cower before anything the French want?

Motion blur is your friend. Our eyes don't have fast shutters!

60khz my word thats a low freq.

The Curious Marc channel mentioned in a recent video about how an atomic clock was flown around the world and was used to get everyone’s clocks in sync.

I had one AA battery in my radio controlled clock that lasted about a decade and still showed the correct time. The battery had only about 0.2 volts left in it and had even started to leak. The display was getting a bit dim though. 🤣

Several years Ago Aldi accidentally sold a batch which take their time from a German transmitter (Aldi is a German company) and so were always an hour fast compared to the time in Ireland. Aldi recalled them but I kept mine. It is still on the wall keeping time accurate to 1 second every 5 million years, but EXACTLY 1 hour fast. I always know what time it is in Germany.

I once took one of these clocks (a bedside digital one) to Burkina Faso and it would still pick up the time signal, although it sometimes took it several hours to do so.

School clocks are slways wrong and they force me to use them, problem solved

There is the 60kHz time station in England and then the 77.5kHz time station in Germany.
English time and Central European time are one hour apart.
The Swiss time station has ceased operations. Switzerland has the same time zone as Germany.

We Americans like to work harder not smarter

Misclickers anyone?

OK, well how does the radio receiver make the clock motor move its hands when you start the clock up off time?

They have it in Japan too

If there is a strong day with tropospheric ducting, does it mess up other countries clocks?

Omg those wiring looks terrible. 😅😅😐

This is much like the NIST station WWVB in the US. They even use the same frequency, 60 khz.

I was an intern in a similar lab in Beijing, and worked on an UI that synchronous multiple devices. It was not the master clock, but still very cool experience.

G-Shock uses it and they called it multi band 6

I live in the UK, and got a very cheap radio controlled wall clock from a charity shop, with the writing on the box all in German.
When I set it up, it zeroed itself at 11am instead of 12.00, and then always ran a hour behind.
It then occurred to me that it must be tuned to receive a time signal from somewhere other than our own.
I couldn't return it for a refund, so I had to dismantle it and reposition the fingers on the shaft at a position which was correct for local time.
Been working in the bedroom like that for 4 years, although I do wonder if ever the German daylight saving time deviates from the uk......

They couldn’t just check their watch?

This channel is an absolute gem

And if you're wondering why "coordinated universal time" abbreviates to "UTC": that's because it officially stands for "temps universel coordonné", and this way neither English or French speakers are happy. Compromise!
