I think time zones should be dropped entirely. It might be weird at first, but people would learn to adapt around the new numbers for the hours. dayshift hours in a country could revolve around whatever their stock exchange decides upon.

personally, I would love to shift sunset to like 5-6 hours after work ends to maximize daylight after working hours. Sometimes in the winter its dark when you wake up, and dark when you get off work, which can't be great for mental health.
