here is the CLOCKFACE script...coded in 3 MINUTES...17 LINES of CODE

[Geoff Canyon]

I considered this option and went the other way for a couple reasons.  
It seemed more natural to leave it in one handler. It takes more  
lines of code to split the handlers up. I wonder what the overhead is  
to have three messages pending as opposed to one.

That said, I think this is the way to go. It solves the display-isn't- 
right-for-up-to-two-minutes problem, and the implementation is about  
as clean as can be.

I think we may finally be close to the optimum solution.
