Have you ever glanced at a clock, and the time goes ahead quite a few minutes within a second? With the 'old' clocks, the hand spins, or with the digital, the numbers go up, and you can see each individual minute even though it's only 1 second. I don't know what the hell this is. No, my clocks aren't broken.
well if it is one of those satellite clocks those things are always screwed up and the tempo to those things are severely messed up. but it may also be that you are zoning out which would explain a lot because perception of time when you become out of touch with reality usually becomes a lot faster than normal. Although I have heard of times when time had slowed down instead.
there are other possibilities as well but I am just creating ideas with the information you gave.
