Reference Time Delta (0xFF,0xD6)
| Description |
Delta time since the last packet. |
|
| Notes |
Difference between the time as reported by the shared reference time field, 0xD5, and the previous output of this delta quantity within the same descriptor set and event instance. The delta is based on the reference time which never jumps. The value is always valid. This can be used to track the amount of time passed between event occurrences. See the manual page on delta time quantities. |
