To this day I wish things like WWV (https://www.nist.gov/pml/time-and-frequency-division/time-distribution/radio-station-wwv https://www.nist.gov/pml/time-and-frequency-division/time-di...) worked better. Folks from Ninja Networks attempted to use something like that on their DEFCON 17 badges (https://www.wired.com/2009/08/hacking-the-defcon-17-badges/ https://www.wired.com/2009/08/hacking-the-defcon-17-badges/) but it required folks to be stationary too long to sync time. Seeing as most major appliances are stationary it would have struck me as a good fit (with the exception of time zones / DST).
