AS3 video (flvPlayback) display time

Hi,
thanks for looking at this post.
Im trying to convert my video player from AS2 to AS3.
Im about 90% of the way there.

One thing thats troubling me is displaying the current time location of the clip

eg 00:00 / 00:00
Most tutorials use netStream and objects but im using flvPlayback.

Are there any suggestions on how to do this?

thanks
