Years of Service Clock

Or do you want a count-down timer to a special date?

In any case, I have the solution. Without further adieu, I give you the "Years of Service" or "Count Up/Down" clock (JavaScript Edition). To use, fill out the simple form below and bonk on the button.

(Note: I know this could be optimized, I just haven't had the time to do it.)
