StationOnlineOfflineDuration Property

The total amount of time the endpoint was offline prior to this notification. Note: There may be certain circumstances where it is impossible to provide this duration (as in the case of an unexpected power faillure or other extreme events). In this case it is acceptable to report a duration of "null", which will be interpreted as "unknown" by the receiver of this event.
