Digital isn't better it's just different. Also a tonne of wristwatches are still analogue.

It absolutely is tho. Usually more precise, 1:1 translatable into written text, can use the superior 24h system and uses the same reading system that is already taught in school anyways.

Right! Just to prove a point, I am going to make an NTP enabled rolex, and sync it to my microsecond accurate local NTP server! :P

[–] Incandemon@lemmy.ca 11 points 3 weeks ago (1 children)

To be fair, I did have a watch that automatically synced itself to the us naval observatories atomic clocks over the air.

[–] r00ty@kbin.life 4 points 3 weeks ago (1 children)

Yeah, but you need to factor in the distance to the transmitter. Going to add at least a few microseconds to your time accuracy!

Latency is accounted for in the sync process

[–] r00ty@kbin.life 4 points 3 weeks ago

Sync process? The other comment was talking about the old receivers for the atomic clocks on SW/MW frequencies. It was a one way thing.

Now in theory if a receiver also had GPS they could account for the distance. But, then they'd get far more accurate time from the GPS receiver so..

The watches/clocks they are talking about listened to WWV, a set of radio stations transmitting from Fort Collins, Colorado. The system long predates the Network Time Protocol you're referring to. Radio controlled clocks/watches had no means for accounting for latency.

Ahh OK my bad. I've only worked with NTP for a long time and wasn't aware of the earlier stuff.

If you're interested in prehistory, listen to this for a couple minutes.
