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?

OK, on the units position of the hour, the vertical section at the lower left never lights up, so at 6:00 to 6:59, it looks like 5:00 to 5:59, but from 8:00 to 8:59 it looks like 9:00 to 9:59. Only at the 10:xx, 12:xx and 2:xx hours does the clock look completely broken.
