maxTimeElapsedSinceLastModification property

Ensures that objects are not transferred if a specific maximum time has elapsed since the "last modification time".

When a TransferOperation begins, objects with a "last modification time" are transferred only if the elapsed time between the start_time of the `TransferOperation`and the "last modification time" of the object is less than the value of max_time_elapsed_since_last_modification`. Objects that do not have a "last modification time" are also transferred.
