Re: [rules-users] How to pass a "global" reference date to rules

You can run your session with a pseudo-clock, advanced to the point in time that corresponds to your reference date. KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(); config.setOption(ClockTypeOption.get("pseudo")); StatefulKnowledgeSession session = knowledgeBase.newStatefulKnowledgeSession(config, null); SessionPseudoClock clock = session.getSessionClock(); // session clock := NOW clock.advanceTime( (new java.util.Date()).getTime(), TimeUnit.MILLISECONDS ); // session clock := TOMORROW clock.advanceTime(1, TimeUnit.DAYS); This rule would fire, today being the 5-Feb-2013. rule test date-effective "6-Feb-2013" date-expires "7-Feb-2013" when $i: Integer() then System.out.println( "Integer " + $i ); end On 05/02/2013, pdario <dario.piantanida(a)gmail.com&gt; wrote:
