I made a mistake in the steps I gave you earlier.  Rather than exiting if 
steps 2 or 3 fail, you should go to step 5.  Those globals should always 
be set (steps 5 & 6) - whether or not the tests in 2 & 3 pass.  Sorry for 
the slip.

> If they are within FN GetDblTime ticks of each other, then go on to #3,

>7) return the flag (true or false).
