Hi Andrej,

The timestamps in the capture file. 
You can run capinfos to display the statistics:
http://www.wireshark.org/docs/man-pages/capinfos.html

$ capinfos -ae test.pcap
File name:           test.pcap
Start time:          Fri Apr 03 06:16:26 2009
End time:            Fri Apr 03 06:17:50 2009

$ editcap test.pcap test_editcap.pcap -A "2009-04-03 06:16:50" -B "2009-04-03
06:17:10"
(you have to use quotes)

$ capinfos -ae test_editcap.pcap
File name:           test_editcap.pcap
Start time:          Fri Apr 03 06:16:50 2009
End time:            Fri Apr 03 06:17:10 2009
