[rules-users] Snapshot of drools engine's state

[IK81]

Thanks for your reply. The way you described this is actually how my
proof-of-concept works. However, I implemented it using two timestamps.
First I use the @timestamp annotation for the property of the event. This
property is set by the event source. Second, I persist a second timestamp
that reflects the timestamp of the session's pseudo clock when I inserted
the event. From my naive feeling I need both for a reproducible replay
starting with the last snapshot of the session. 

Thanks for the hint concerning the sliding window. This is the drawback of
the approach of externally controlling the clock - it limits the time
granularity of these not-event-B-after-A rules. But in my case I can live
with this restriction that the rule might fire some seconds later. I wished
there would exist a possibility to register for a kind of callback when to
externally trigger the event engine again - however, I haven't found
anything related to that.

Thanks & best regards,
Ingo
