I have a file that needs to be analyzed. In the same frame, I found that there is a difference of 30ms between tcp.time_delta and the time of http.time. questions: What factors affect this difference, and is it related to memory, operating system, and system tcp kernel parameters?

TCP and HTTP are two different protocols. Each with its own timimg.

For example tcp.time_delta can refer to the previous TCP-ACK, while http.time can refer to the previous HTTP request in another (earlier) packet than the TCP-ACK.

If you filter on http then the TCP-ACKs are not shown, filter on tcp.stream instead.
