You don’t even need that. My microwave is wifi connected but still can’t keep time. Instead of using NTP like any appliances or industrial control system in the last decade+, it syncs to your phone time though an app.
RCC has been available since the 80s. Much of the wold has been covered by radio time broadcasts that would be used by devices to set their own time but somehow it didn’t start to become really commonplace until wifi allowed for 2-way communications 🤔

Wtf.
Fuck IoT
All my homies hate IoT
If you have wifi you need to store it’s credentials somewhere, and you run into same issue.
Actually automatic way would be to just take GPS signals clock time.
