[rules-users] Conditional 'not' invalid for event streams?

Barry,
I did not run the code bellow, but drools uses the temporal distance
algorithm to calculate how much time it has to wait on a "delaying not"
before activating the rule. So, the first question I have is what are you
using as timestamp for the events? the time they are inserted into the
engine or a timestamp attribute?
