I haven't heard of anything like that in camera. It might be possible using some sort of software to control the camera on a computer that would signal the camera to take a photo
I do timelapse all the time with Canon EOS viewer/capture utility running on a laptop. Can do 1 to 1999 shots, minimum 5 sec interval, max 2 hours. I have used Canon EOS-1D or Ds bodies. If you run the utility on a Mac, the 1999 frame limit does not apply for some reason.
New Nikon D300 has a buit-in intervalometer, every camera should have one. Maximum number of shots is 999. No laptops needed. My favourite.
