Sounds pretty similar to tcprewrite, isn't it?

Dev list,

I wrote a command line tool that you might want to include in the
Wireshark bundle of command line tools.

rewritecap is a tool for rebasing a PCAP file, editing layer2 and layer3
addresses, and updating ARP packets. PCAP-ng files are not currently
supported. This tool will accommodate 802.1Q tagged frames and
Q-in-Q double tagged frames.

The timestamp changes allow you to rebase the PCAP file to a new date
without changing the actual time of day or the inter-frame gaps. You can
also timeshift all of the packets by a value in +/-00h00m00s format.
Multiple timeshifts can be specified at the same time by separating
them with a comma, thus --time-shift=2h,-3m

./rewritecap --help
./rewritecap -f test.pcap -n test2.pacp -y 2016 -m 3 -d 10
./rewritecap -f test.pcap -n test2.pcap --ip4 10.0.2.32 --ip4-new 2.2.2.2
--mac 68:A8:6D:18:36:92 --mac-new 22:33:44:55:66:77
./rewritecap -f test.pcap -n test2.pcap --time-shift=2h1m3s
./rewritecap -f test.pcap -n test2.pcap --time-shift=2h,-1m

rebasecap is Apache 2.0 licensed and will compile to a static binary for
Linux and Mac OS X.  It should also compile to a static binary for Windows
but have not tested that.

It is written in Go 1.5.  Code, install, and compile instructions can be
found here:

Thanks,
