Date Modified values in File List when branching

[IFU]

Up to now, I have been relying on the “Date Modified” values in Flare's File List to determine what source files have changed between say version A and version B of a document.
After watching Paul Stoecklein's webinar on the world's oldest living Madcap Falre project, I have decided to adopt Git and more specifically branching.
It comes as a bit of a shock to see that the Date Modified values in File List have become practically useless for my purpose since they get updated whenever I have modified a file in say Branch B and now go back to Branch A. The timestamp for the file in Branch A corresponds to the time I have checked out Branch A and not the time I actually modified the file in Branch A.
Is there some sort of workaround or other Flare feature I could use to figure out what files have really changed in a project in a given branch?
Thanks

I suppose one answer is to use the git diff command.
