I'm more concerned about your glib statement of "same exact moment"... 
we'll have none of this same exact stuff without careful specification 
of the reference points, accounting for light time delay, etc.

Now, let's get right to it... on that chime... is it the time when the 
hammer hits the bell, or when the peak of the first cycle occurs, or what?


Sounds like a cool idea...
