While it doesn't provide the time at which the configuration was actually applied, this isn't actually useful because the configuration results in messages sent to the Control-Server and the protocol doesn't allow the actual time of execution of the message to be returned. Not that I think it would be useful to do anyway. So I don't think this proposal is required in order for draft-cmzrjp-ippm-twamp-yang to specify a mechanism for TWAMP test sessions to be started.
