Timer problem

I initiate a timer as soon as I enter a specific frame in my movie, however the time that I get is the cumulative time for the entire time that the movie has been running…

If that is worded to…confusing…then let me just state what I need. I need a way to start a timer when I enter a new frame. However when I use an ENTER_FRAME event listener, I get the cumulative time that the entire movie has been playing.

Thanks for your help!
