A common issue that I am looking into is setting the execution date to test future or legacy rules (i.e., with dates that are not the system date.) A number of users have posted about TimeMachine, TimeServices and the perils of setting the system date - but a JIRA lists TimeMachine as being remove

Hmmm, that could be it! I'm not sure I understand what you mean by that "guard" object. Would that mean that I should insert some dummy object in a script node (action node) before my rule node and change its value inside this rule, so the rule could be triggered when the second and third instance
