.1.3.111.2.802.1.1.20.1.2.14
Object
This timestamp denotes the system time when the most recent change in grandmaster frequency occured, due to a change of either the grandmaster or the grandmaster time base. 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), and when the ieee802AsCurrentDSGmTimebaseIndicator managed object (see 14.3.5) changes.
