Accessing the seekbar timing through JavaScript....

I've seen a few post relating to this not being possible in SL. However, I'm wondering if there might be a way to access the timing of the individual slides seekbar time line?  Maybe with a JavaScript file that is linked to the course via the story_content folder? Then it could be saved in a variable and utilized on the individual slides.

Has anyone done something like this or know if it's possible?

Thanks!
