12 hours. Back when I used to build pr0n sites, I had one a guy said he'd give me a $1000 bonus if I got it up by 5am. That included indexing 2000 images, graphics and navigation, and db work on the server remotely.
I was tempted to re-fill my super big gulp my wife brought me while I was working. I got the site up by 4:30, got the bonus, and decided even a thousand dollars wasn't enough for the pain my kidneys were in.
HURTS!
