Perpetual Video Web Site

I need a developer who can make a webapp that when a user visits it detects the users time zone and shows a video of a "human clock" for that time, it would have to be perpetual like if they kept the web site up, it would jsut loop for 24 hours. Here is an example of the type of video I am talking about [login to view URL]:1925953 We would provide the 12 hours of video (it would be on a loop), but your software would have to determine where to start playing it so the time was precise. An example of something kind of like this is [login to view URL] Please include time frame in your quote, we have not yet made the video, as we will need instruction from the coder on how the video should be made in terms of how we break it up.
