1.  Introduction

   Time synchronization protocols, Network Time Protocol version 4
   (NTPv4) [RFC5905] and Precision Time Protocol (PTP) Version 2, a.k.a.
   IEEE-1588 v.2, can be used to syncronized clocks across network
   domain.  In some scenarios calculation of time packet of time
   syncronization protocol spends within a node, called Residence Time,
   can improve accuracy of clock syncronization.  This document defines
   new Generalized Associated Channel (G-ACh) that can be used in Multi-
