This site is a pretty exhaustive listing of about any kind of Internet clock or counter.
A few of the clocks listed:
- Digital Doomsday clock
- Binary clock
- Martian clock
- Salary clock — for super sadness compare your accummulating wages to that of, say, Tiger Woods
- US National Debt clock








You left out my personal favorite.
time.gov — the official time site for the US government… great to set your PC clock by, or figure out what time it is in some other time zone when you don’t want to do the math.
