I cannot locate a "time" property for a video texture

I need to add a shuffle slider to my scene to scrub through the videoTexture.  I don't believe there is a property for time such as in buiding a direct HTML5 video player.  If there is one such as VideoTexture.video.time() please let me know.  Otherwise, my solution is to load both a forward and backward playing video and manipulate those.  Lot's of work. 

Thanks.
