Auto GPS Time does not work for me. Does it work for anyone?

GPS time does not work, and nor does GPS. The time feature would be so useful for those few who wish for very good time synchronization, would it not?

[Peter Kilmister]

No idea. I wear an old-fashioned clockwork 'tick-tock' watch. I can't be bothered with GPS to tell me the time. My watch is also a compass, because I learnt how to use it when I was a child. Mind you, on a day like today when the sun was invisible behind the rain clouds I suppose GPS might have been useful.

The subject referred to one in which a poster was looking for an accurate time protocol for his M10.

In cameras which can be accessed by Fotos, the camera synchs up with the time signal from a smart phone or iPad.  Since that comes from the nearest internet or telco time information, it may not have atomic clock accuracy, but it's better than needed for Gov't work.

Nearest Internet, Telco might use NTP, PTP provided by  real time, delay calculated connection to valid time reference server. PTP sync rate is up to 128 per second from master to slave.

My company phone  is more accurate  what PC provided by company I work for. They have sold 36000+ timing devices (just one particular model, from three available).

I did not know that. Thank you.

What do they do with the second set of 8-bits?

It has been years since I read the IEEE papers. The time protocols are ingenious. In my day, NTP was good for ~1second accuracy. PTP blows my mind with its promotion of the most accurate server.

FWIW, don't all apple devices still go to their cluster of time.apple.com servers?

The Visoflex 020 works fast and reliable if weather conditions are good (cloudless sky).

Cloudless. So that pretty much eliminates the UK.
