[rules-users] Unpredicatable output with Temporal rule

[Edson Tirelli]

   Since you are not declaring to the rules engine what is the timestamp
attribute, the engine uses the timestamp of the session clock at event
insertion. What kind of session clock are you using? how are you firing your
rules (fireAllRules() or fireUntilHalt())? How frequently are you feeding
the events into the working memory?
