Having moved to and lived 7 years in Southern Arizona, it did not take long to figure out why one extra hour of daylight was not welcomed. By not having daylight savings time, this one more hour of darkness in the evening is helpful. It is damn hot here, today again we were 100°. Right now the sun went down at about 6:15 on daylight savings time it would have been 7:15 pm. When it is hot outside, when the sun goes down it just feels cooler. Most people will go outside on a workday at 6:00 pm and socialize to about 10:00 pm because sleep for the next day helps productivity on the job. During daylight savings time, outside would have less darkness between 6:00 to 10:00 pm.
