OK, I've just checked in a change to, for Modbus reply packets, giving the time difference between the matching request and the reply. It shows up right after the frame number of the packet containing the matching request; the field name is "modbus.response_time", and you can make it a custom column so it shows up as a column.
It will be available in Wireshark 3.0; if you want to experiment with it, you can go to the "Go Spelunking" section of the Wireshark download page, select one of the download sites (3 in Europe, 2 in Asia, 3 in the US), go to "automated", and select:
Pick one of the "wireshark-3.0.0rc1" files - choose the newest one. These are "release candidate" builds, and may have issues (the first announced release candidate had some macOS issues that needed to be fixed, for example). Report any problems on the Wireshark Bugzilla.
If the request/response time information there solves the underlying problem you're trying to solve, let us know.
