    There are radio controlled clocks which theoretically shouldn’t be wrong. At least as long as there isn’t a battery or motor issue…

        Sometimes they have it written on the clockface. I don’t think that’s a general rule though.

        In the same way there are digital clocks that can be wrong too though.
