At exactly 12:00, the hour, minute, and second hands are all pointing straight up.

Are there any other times that all three hands are superimposed?
If so, when?

I think that once every hour there is an exact moment in which all three hands are superimposed upon each other.  Fore example, somewhere around 6:33, 7:38, 8:43, 9:48, etc.
