How can I automate an HDR sunset time-lapse using exposure bracketing?

I want to shoot a sunset time-lapse where each final frame is an HDR image made from a bracketed exposure sequence. In other words, I need the camera to capture an exposure-bracket burst every set interval for a period of time. Is there a practical way to automate this, either in-camera or with tethering software such as digiCamControl?

In addition to @BShaw's answer, if you're a Mac/Aperture user the following blog post might help:

It's a script to take a specified number of photographs at a chosen interval between them. I have used the script successfully to create time-lapse videos. My guess is, if you set your D300 to bracket the exposure, then set the script running while your camera is tethered, it should take the appropriate exposures if the interval between shots is long enough.

This may or may not help, but is another option at least.

Yes—this is generally possible if you combine interval shooting with your camera’s auto exposure bracketing. Set the camera to bracket each shutter release, then use an intervalometer or tethered control software/script to trigger a shot sequence every X minutes.

From the community input, one working approach is tethering a Nikon D300 to a Mac and using an AppleScript-based interval shooting setup. If the camera is already configured for bracketing, each trigger should fire the bracketed sequence, provided the interval is long enough for the full burst and file writing to complete before the next cycle.

The key practical point is timing: make sure the interval between sequences is longer than the time needed to capture all bracketed exposures and save them. After shooting, you would merge each bracketed set into HDR frames and assemble those into the final time-lapse.
