Yes, and would I suggest limiting the scope of the present series just to allow changing the global, device-level time stamping layer administratively. Trying to support multiple time stamps from different layers is a much larger development project, and it will require new kernel/user interfaces. (Of course it would be grand if the series is forward looking to the day when time stamp reporting expands beyond the current hw/sw cmsg.) Thanks, Richard
