Yes, but at the cost of running crazy air conditioning. The only time I visited Phoenix I arrived near lunchtime and was baffled to be wandering around a seemingly modern city where the streets were entirely free of people. I felt like it I was in the opening scene of a zombie movie or something.

Personally speaking I've never seen much value in living by the clock if it puts you in conflict with the seasons. The notion that people everywhere should adhere to the same schedule regardless of local conditions is inherently absurd.
