Wireshark · Wireshark-users: [Wireshark-users] add timestamp to fieldlist in wireshark

["haneugen@xxxxxxxx" <haneugen@xxxxxxxx>]

Hi,
I am using tshark to extract all the fields I need out of a capture and to further process them. But as you know processing becomes much easier when working with numerical values instead of having to parse strings thus I would like to add a field containing the unix timestamp (relative_time is unfortunately not sufficient) to the tshark field list. Does anybody has an idea how to do that, e.g. which field to add?
Thanks in advance.
Cheers
