The good thing about digital clocks is that you can easily tell what time it is. With analog watches, when you look at your watch, then look up, you still don't know what the times is. So you look again. You know you had that experience. That's one of the things we remember the late George Carlin once said.
If you want to make it harder, try this clock or time machine minus the flux capacitor. This is annoyingly loud though so we suggest you use it in your bedroom if you are hard of hearing. Oh wait, we meant deaf. Another thing Mr. Carlin said; avoid soft words.
