I've rehearsed a talk using OpenOffice.org Impress, and I want to know the total time taken. How can I do this?
After you've rehearsed your talk, you can look at how long an individual slide took by looking at "Automatically after" in the "Advance Slide" of the "Slide transition" Task Pane. OO.org documentation.
It'd be nice if you could view the times of each slide all at once, or better yet just get told the total.
