[rules-users] Rules Effective Date

Hi I am a newbie for Drools and googled for a good time. I would like to know if Drools 4.0.7 and Drools 5 have anything like an "Effective Date" concept? We have a requirement for having a rule written by the Business Analysts and takes effective for a future date, without restarting the application. Is Rules Engine intelligent enough to pick the rules depending on effective dates? Thanks a lot for your help. SRINI
