Code to get timestamp in tcpdump output

Hi all, I’m almost new to the network but I happened to use tcpdump for my research. I wonder where exactly the timestamp of tcpdump comes from. I'm working on Linux. My best guess is that it is from net_timestamp_check() function which is called by netif_receive_skb_internal() in net/core/dev.c for incoming packets. http://lxr.free-electrons.com/source/net/core/dev.c?v=4.0#L3794 But I'm not sure. In addition, I would like to know where is the code for outgoing packets. Can anyone help me out? If this is not the proper mailing list for this question, I apologize for that. Best, Jintack _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
