I don't beleive that each frame contains a timestamp of it's own.
The video will have a timestamp either of it's start time, or end time depending on the firmware of your camera. You then have to count frames at the framerate of the camera.
So if the video timestamp is 13:00:00 (1300 hours exactly) at a recording rate of 15fps, the 30th frame would be 13:00:02

thanks tlhintoq.. for your reply...

but i think each and every frame has its own timestamps.. or a stream .. .

which may be used for syncronize the video and audio stream.. in video file.
