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.
|
server→client |
SystemTimeMs: systime_ms, PosixTimeMs: posix_ms |
| 0x03 |
PayloadTestRequest
Optional This command provides a means for certification tests or manufacturer's internal tests to validate particular command handling and encoding constraints by generating a response of a given size.
|
