client→server |
EnableKey: octet_string, EventTrigger: int64u |
| 0x01 |
TimeSnapshot
This command MAY be used by a client to obtain a correlated view of both System Time, and, if currently synchronized and supported, "wall clock time" of the server.
|
client→server | None |
| 0x02 |
TimeSnapshotResponse
This command SHALL be generated in response to a TimeSnapshot command.
