Quote -  It rendered for 9 hours because I turned it on this morning before going to work. :)

I ran a few test renders last night on the same scene getting the sun direction and camera position right and they were acceptable quality within 30 minutes.
The overexposure is on purpose, gain is already low at 0.04 but I cranked the fstop down to all the way to 0.7, exposure at 1/250, iso at 80.

If you adjust the gamma under linear you can also get the image toned down. Just play around (I've been doing it for days....lol).
