Currently, i install TCPDUMP to get all the packets between a cellphone and a camera. i want to know when a packet is sent from the camera, how can i use the value TSVAL,What is the unit? ms or us or any other unit based on the processor?
While the TCP timestamp option is defined in section 3.2 of RFC1323, "TCP Extensions for High Performance", the timestamp clock itself is described later in section 4.2.2, with the following statement of particular relevance:
Based upon these considerations, we choose a timestamp clock
frequency in the range 1 ms to 1 sec per tick.
Basically, the value is implementation dependent.
