Rules Engine: Add Rule DateTime as a field option

We use the Rule Date field to load a “snapshot date” to certain objects for historical tracking. It would be very helpful to be able to load the Rule Date as a DateTime field for greater granularity when troubleshooting. For example, if we have a certain rule that updates values every 2 hours, the time granularity would be helpful in understanding when an error may have occurred (incorrect value loaded, etc.).
