Wireshark-users: Re: [Wireshark-users] PCAP date change ?

Development versions of capinfos have the -S option, which should make this easier:

   −S  Display the start and end times as seconds since January 1, 1970.
       Handy for synchronizing dumps using editcap −t.

You can use editcap (shipped with Wireshark):

  -t <time adjustment>   adjust the timestamp of each packet;
<time adjustment> is in relative seconds (e.g. -0.5).

(from editcap -h)

Cheers,


Sake
