A single time zone within a small state, or two or three within a larger state, still has some utility for local events. But yes, in the age of smart watches, there’s no reason not to skew time by a few minutes every night for a more consistent experience. Using local noon as an anchor isn’t optimal because wake up time will still vary. I argue that wake up consistency with sunrise is the most important feature for humans.
