When using a pseudo-clock, I have always used
   SessionPseudoClock.advanceTime(long x, TimeUnit unit )
to advance the clock to some reasonable value, especially so
if the timestamp is an attribute of the event fact.

This is strange - if there are no declare X @role( event ) end in your DRL,
there shouldn't be a complaint that the timestamp has a value equal to
zero. Please check the absence of such declarations.
