What do you set your watches to?

[Tall_martin]

Just curious.

As a wee kid occasionally I was allowed to phone 123 and set my watch to that.

Then it was the beeps on radio 4.

Now all my radios are on dab mostly I use the time on the work computers and don't bother with the seconds.

What do you use?

[Mazinbrum]

Time.is

Synch them with my phone.

As this is PH, you will have a high performance Ubiquiti/Unifi network at home.
The right solution is the addition of a Precision Time Protocol Grandmaster clock system with a roof mounted GNSS antenna.
This will provide the kind of precision needed at the relevant cost/performance level expected on these boards.

you'll also know that GNSS is off by a few seconds compared to UK time.

I always rely on my deadbeat longcase regulator with its mercury pendulum bob suspended on an invar rod - either that or the town hall clock.

I would be very surprised - there are at least four GNSS constellations available from the UK (GPS, Galileo, GLONASS and BeiDou) as well as several augmentation systems that improve accuracy and/or allow for error removal.
Which is why powerfully built director types also ensure they have a multi frequency, multi constellation GNSS receiver.

These are an excellent mix of Piss taking and helpful answers

I check mine against the station clock. I've heard that the station master checks the station clock against the clock on my east tower but I couldn't possibly comment.

I have my watch butler set all mine for me.

I use the new optical atomic clock at JILA (which takes into account gravimetric variances observed through General Relativity) and set the hands on my Benson accordingly.

Usually though I just look at my phone and set the hands on my watch to say the same thing. By the end of the day it's only drifted a bit. The Seagull on the other hand can drift by up to 2 minutes in 24 hours which is probably why I always seem to miss the 17:28 tube back home although that could also be TFL making stuff up as they go along.

I used to use Time.is as mentioned already, to set my Explorer, but I now have a G Shock with Multiband 6 and Bluetooth connectivity, which updates itself up to 4 times within a 24hr period.

Seems excessive, but I enjoy the technology nonetheless.

I use it with a delay offset with a rubidium oscillator, I don't want to get the launch time of my nukes wrong.

The simple solution I have is a radio controlled wall clock in my study which updates itself once a day overnight. The drift of the quartz movement over the following 24 hours is negligible. Then if I wish to be accurate I use this. Or if close enough, then the time on my phone or news channel and restart when the minute changes. Some clocks only need to be approximately good enough!
