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:
