title: Epoch and wireshark capture
body: <p>I have a .pkt sniffer capture. When I read each and every packet within the capture from my C application, I observe a radio header appended. The radio header contains the time in epoch for each and every packet. I would like to find out the time difference between two packets in terms of milliseconds. I am not sure how to diff two epoch values and find out the time difference in milliseconds. Please help me with this.</p>
