This is so simple that I almost hesitate to mention it. I use
javascript to set a cookie on the client when they submit. The cookie
holds the system time of the submit. Then at the bottom of the newly
render page I have a line of javascript that subtracts the saved
cookie time from the current system time and displays the difference.
