Curiously, if it was abolished, the “crack of dawn” here in Nashville during June would be at or around 3:50am. The last bit of sunlight goes around 8:45pm (CDT). I’m thinking of splitting the difference and bumping it a half-hour. Still, I think we should probably “adjust” the whole country to make it optimum for everyone along longitudinal lines as opposed to state/county.
As someone who one ran frantically to the departure gate at the Memphis airport only to find out when I got to the gate that my flight left not in ten minutes but in 70 minutes because, unbeknownst to me, Memphis (unlike East Tennessee) is in Central Time, I can’t say that I’m a fan of states (much less counties) being divided between time zones. And if the crack of dawn in Nashville is around 4:50 a.m. in June *even with Daylight Saving Time*, then clearly all of Tennessee should be on Eastern Time (along with all of MI, IN, KY and FL and the state of AL); New England probably should be on Atlantic Time.
