There is an obvious solution which never gets discussed: re-draw the boundaries between the time zones a half hour or so, and stay on "standard time" all year.

There is an obvious solution which never gets discussed: re-draw the boundaries between the time zones a half hour or so, and stay on "standard time" all year. Move them further east, and sunrise and sunset are earlier by the clock for people who have been changed from one time zone to another; move them further west, the opposite. Follow state lines if you must, but probably better not to.
