Fast clock, slow clock (Posted on 2007-04-11)

At a certain time of day, every day, my clock appears to be an hour fast. At another time of day, it appears to be an hour slow. It is neither fast nor slow. What's wrong with it?

Solution: (Hide)

The LCD light on the lower left of the hour digit is broken, so that the hour number 6 appears to be a 5, and 8 appears to be a 9. During hours 2, 10, and 12, it will be clear that the clock is broken.
