I am debugging a network issue on a system running Connext 5.3.1. My tcpdump contains several million messages. I am trying to calculate from data available in tcpdump the time difference between the source timestamp and the reception timestamp. I understand that the first data available in the 0x09 INFO_TS submessages of a message. As an example, I have the following snippet from tcpdump:
0x0030: 0901 0800 e9f2 b766 c4b7 3ea0 1505 5c00
