I think you have missed the point this is not so much about keeping time down to the nano-second
I was suggesting NTP, not PTP.
The WWVB clocks being discussed here come in a plethora of decorator styles and display varieties ( though most are old analog dials) some up to 3' in diameter.. They are battery powered so one does not have to connect them to external power source. They serve a dual purpose .... for the lady friends who keep us fat and happy they are pleasing to the their sense of form and feng shui (If momma aint happy ..aint nobody happy)
Then find a more rationally-minded wife or partner. . For the engineer in us we know that the time is accurate to
the second and we don't have get out the step ladder to crawl up there and reset the clock twice a year when daylight savings changes over. When I was a road warrior I had a wrist watch that kept WWVB time and I always knew down to the second how much time I had before I missed the next flight or train out of Dodge. ( I haven't worn a watch by the way since I retired in 2008 !) Nowadays I suppose you could build/buy one that talks to your WLAN but I suspect the battery life is not quite as good as the current WWVB version which can run off a watch battery for 5 years.
Well you would have to bother with the rather-pointless project of building a WWVB simulator, taking care not to cause interference. Stationary clocks do not have to be battery-powered. Yes, battery life would obviously be a problem for typical smartwatches, but assuming a rational mind, virtually everyone will opt for a smartwatch over a WWVB-synchronized dumbwatch, despite the battery life penalty incurred.
On the other hand I know I can sleep better at night knowing my WWVB clock has not joined the dark side and is mindlessly helping the terrorists bring down the power grid 8^(
What a brilliant idea---lets refuse to embrace computerization and the transition to Internet-of-things (which should've happened in the 80s) out of fear of the expansion of botnets; furthermore, lets roll back computerization, and maybe even eliminate all computers? Why have progress when we can have regress? Of course, we shall disregard the fact that there are a wide array of all sorts of security countermeasures (correctness proofs, sourcecode auditing, multifactor authentication, ASLR, DoD-style MACs, firewalls, IDSs, honeypots, tarpits, etc.) and the fact that all properly-designed high-security and/or critical systems are either completely air-gapped (SIPRNet, JWICS, NSANet, stock exchange internal networks, etc.), or are unidirectionally interfaced with the Internet (many SCADA sites, etc.)
