Does powerpoint have a time display of show?

[paniko]

When creating a slide show I am trying to find a way in PowerPoint to show the elapsed time of the entire slide show. Trying to place a music score into the show so it ends with the last frame is a guessing game. SoundForge (music software) shows the elapsed time of the music score but I cannot simply synchronize it with the slide show other than guessing the elapsed time of the slide show. Have tried 3 different slide shows with 50 slides and each show seems to time out differently even though I have slide transitions set to .03 seconds on each show.
Hoping for some help.

I don't know what version of PP you use, I use 2003
go to Slide Show menu on the menu bar, then choose Rehearse Timings, PP will star playing slide show, and you can see a time indicator on the top-left corner of the slide show. after you finish your slide show, PP will tell you the play time.
