should this be:
               S   0        1    S
           ..__     ........_____    ...
               |   ^        ^    |   ^
               V___|........|    V___|.. 
              T0   T2       T2  T3

		  t2-t0 > t3-t2 => 0
		  t2-t0 < t3-t2 => 1

I would think that the transition from low to high would be where the
timestamp
should happen.  If it occurs early it is a zero and if it occurs late it is
a one.
