The RT_PARAMETER_DATA structure contains the parameter data for the report timestamp command.
ParameterDataLengthIndicates the number of bytes that follow in the parameter data.
OriginIndicates the most recent event that initialized the returned device clock.
| Value | Meaning |
|---|---|
| 0 | Device clock initialized to zero at power on or as the result of a hard reset. |
| 1 | Reserved for future use. |
| 2 | Device clock initialized by the SET TIMESTAMP command. |
| 3 | Device clock initialized by an unknown method. |
| 4 to 7 | Reserved for future use. |
Reserved1Reserved for future use.
Reserved2Reserved for future use.
TimestampContains the current value of a device clock.
