What you suggest though could be useful to set watches or microwaves to the correct local time using OTA data like the clocks that derive their time from atomic clock radio signals. To my knowledge that signal doesn't include any TZ info. Seeing the low value in these devices I doubt there will be pressure to pay for the infrastructure for such a solution.
The atomic clock radio signal is in UTC. You have to configure the clock for a base timezone, but the signal does include embedded DST information at the day level (the clocks are hardcoded to make the transition at the next 2:00 local time). AIUI it's centrally located for the whole country, so they can't send "what timezone you are in now" data the way cell phone towers can.
