about 12 hours, from 8am - 8pm
We were working on an iOS build for a demo and were told that day was the deadline for having code merged. I got kinda shafted cos I needed someone elses code merged before I could finish mine. It got merged at like 5pm and then everyone went home leaving me with a ton of merge conflicts to deal with. I gave up at 8pm and went home. Found out the next day that the deadline was horse crap anyway....
