Technically no. Work and School dictate when we get up and go to bed. It's all relative. We could create a timezone where 12:00PM is in the morning. We are just used to this idea that morning, afternoon, evening, and night need to correspond to specific time values. For example, China uses just one timezone. So local regions just adapt to what logically makes sense. In a perfect world, local regions would adapt to the amount of daylight we have for each season, like it was before timekeeping and timezones. So school and work would shift when they start based off the rising of the sun. This isn't practical though for multiple reasons. It would cause chaos and confusion for work shifts, scheduling etc.
