Science Questions

I have two radio-controlled speaking clocks that are identical but one’s two year’s older than the other. They speak at different times. Why is that? David, Harlow

We're actually not sure about this one!

Most radio-controlled clocks update themselves once a day, but cann't do so if they can't receive a strong enough radio signal.  It's possible that one of the clocks has a weaker antenna, and so isn't receiving a signal, and has fallen out of time.

Please let us know if you can think of any other reason for this!
