An embodiment of the present invention is a technique to provide time sensitivity to an inference engine. A time function is associated to an event object and a rule object in a rule engine using a dynamic object. The event object represents one of an event and a fact. The rule object represents a rule associated with the event object. Time-related information on the dynamic object is obtained using a timed fact object and the time function. The timed fact object corresponds to the event object. A time queue containing the timed fact object is updated using the time-related information. The updated time queue updates status of a condition of the rule.
