I have made a geoevent service to detect a car to enter a geofence and I have a alert featrue service that when the car inside the geofnce new featrue will update to .When the car is outside the geofence I want the featrue in alert would disapear after 1 minute, in fact it would be there all the time.I think I made the "Maximum Feature Age (Minutes):"  ok.
