A BIG thank you to whoever added that feature all those years ago.
I think I've used it once before tonight. This time it really saved me from major brain strain, thank you again to whoever.
You can measure time between two points by marking a loop region.
Where it saved my bacon was I did a project that ultimately rolled three projects into one e.g. show1, show2, show3 all end to end in a compilation project.
Then the client sends back timecoded comments from watching the DVD. Except project show3.veg starts at 0! By changing the ruler in show3.veg to match where that video ended up in the compilation I could exactly follow the clients comments by timecode.
