Practically you must do at least one. The point of fussing with time zones (or the start-time for school/work, if you're in some weird place where people are capable of that) is so that you can go from "no morning or afternoon sun" to "morning or afternoon sun". You could tweak your 8.5 hours of daylight so that the sun rises at 6am and most people go to work/school in the sunlight and the sun sets at 2:30, or you could tweak it so that the sun rises at 10am and most people get some evening sun until 6:30. It's not great but it's an option, instead of demanding the sun rises at 8am and sets at 4pm so that noon is noon and no one gets to enjoy it.
