I've always "loved" the farmer argument; like a farmer is going to check the clock and say "well, even though the sun is coming up, I can't head out into the field until x time."

Of course you could argue that some/most cities have hours when contractors can make noise and in the summer they want to start early to avoid the heat. Of course that could be a simple ordinance change saying something like work can begin at sunrise rather than saying 7:00am.
