I have one. It's an add-on for a car with internal and external temp
sensors. I picked it up when I was in Munich last year and didn't
realize that you _can't_ set the time manually. I was figuring that it'd
be fun to have a thermometer, and the fact that we don't have the same
clock transmitter in the States wouldn't be a problem. It is. I have a
car thermometer that knows what time it is in Germany.

There is a transmitter in Colorado, but I am not aware of any hobby projects
to take advantage of it. They did start building VCRs that could set
themselves off of a time signal broadcast over PBS stations, but I think I
heard something about that being a failed program and being discontinued
at some point. When I heard about it, it suggested to me that if the
atomic clock radio signal had good propgation characteristics, they would
have used that instead of a time signal from a TV station, but perhaps it's
more an issue of Daylight Savings Time.
