About clocks:

I hate to have to change the time of the oven twice a year. It annoys me :P

I have a nice, cheap, small alarm clock by my bed which gets the current time over air (some sort of radio signal, probably https://en.wikipedia.org/wiki/Radio_clock ) => works great, in the past it maybe needed up to 30 minutes or so to do an initial update of its time after a change of batteries, but then it always worked perfectly.

Why aren't more appliances using that? Shouldn't even an oven, maybe having a small antenna embedded in its front, be able to get that signal?
