The value of sysUpTime on the most recent occasion at which
any one or more of this general statistics counters suffered a
discontinuity. The relevant counters are the specific
instances associated with this interface of any Counter32 or
Counter64 object contained in the SCTP layer statistics
(defined below sctpStats branch). If no such discontinuities
have occurred since the last re-initialization of the local
management subsystem, then this object contains a zero value.
