Standard time isn't perfect though. The more west someone is in a time zone, the less sleep they often get because the sun goes down later in the evening. Some have estimated it to be as much as 20 minutes of sleep less, which is very significant over time.

What we really need is for schools and work to start later in the day for a larger number of people so that the morning can be a time to sleep in, or if you are a morning person do your morning things.

I almost think that getting rid of time zones in the US might make it so that people are more cognizant of where the sun is and so that society runs on a more local time.
