I would like to get TX packets timestamps and for that I was trying to parse the Timestamp field in the STC signature in the packet payload. But what I see is not a full timestamp, it is a relative one and it seems that there is a reference timestamp used by STC and only the relative timestamps are written in the STC signature.
Could somebody confirm this ?
If so, Do you know how can I find this reference timestamp so I can find the full timestamp at the end of each packet ?
