Stopped Clock

Sometimes, when a clock is ticking down, and I want it to tick faster, it actually ticks slower, because the second my eyes land upon the number when it has just barely ticked, the number lingers there for about 2 seconds. How can a second be 2 seconds? What is happening? What the hell is going on? WHAT IS TIME. We think we understand it, but we do not. We don't understand a thing. YOU KNOW NOTHING.
