Object

scalar 0.01 secondsSNMPv2-TCTimeStamp

This timestamp denotes the system time when the most 
recent grandmaster change occurred in a gPTP domain. 
This timestamp is updated when the 
PortAnnounceInformation state machine enters the 
SUPERIOR_MASTER_PORT state or the 
INFERIOR_MASTER_OR_OTHER_PORT state (see 10.3.11 and 
Figure 10-13).

How SNMP and these commands work

Scalars have one instance, identified by the .0 suffix.

Type Description

The value of the sysUpTime object at which a specific
occurrence happened.  The specific occurrence must be
          
defined in the description of any object defined using this
type.
          
If sysUpTime is reset to zero as a result of a re-
initialization of the network management (sub)system, then
the values of all TimeStamp objects are also reset.
However, after approximately 497 days without a re-
initialization, the sysUpTime object will reach 2^^32-1 and
then increment around to zero; in this case, existing values
of TimeStamp objects do not change.  This can lead to
ambiguities in the value of TimeStamp objects.
