When I use the command below: $ tshark -r fie.pcap -T fields -e frame.number -e frame.time -e ip.src -e ip.proto

I get the time with the date including. How can I display just the time (not the date) only in seconds (not hours or minutes). if I add -t a before -r, I still get the date displayed together with the time in hours, min and seconds. After sorting by IP source address, I am trying to determine the duration of those flows that have 100 packets or more for each IP source address. Thank you.

You're not looking for frame.time but what presented in the Time column (that's not the same).

$ tshark -r fie.pcap -T fields -e frame.number -t e -e _ws.col.Time -e ip.src -e ip.proto

Thank you for your help Jaap. Just to clarify (for me):

I get a display with 4 columns/fileds: frame#, time (in secs), ip source, protocol, so "-t e _ws.col.Time" , all this expression displays the time in seconds, correct?

The last column I wanted to display whether UDP, TCP or ICMP traffic, so I don't think ip.proto was the right filter because I just get a column with the number "6". What would be the right filter for that purpose?

Thank you very much.
