About the only thing that people truly synchronize on is that lunch is around noon, but practically there's an hour of flexibility on when people actually eat. When is the official time for work to start or end? Maybe 7, 8, or 9? Office work seems to end around 5 or 6. School starts sometime between 6 and 10 AM depending on grade and locale. My point is that there already is no standard wake/sleep schedule. Noon may be the tightest bound on when people all want to be doing the same thing, but importantly that happens after everyone is already awake so picking DST or ST is arbitrary. People who want sunset or sunrise to occur earlier or later in the day have a conflict coordinating with other people in their life, not a problem with official timezones. Maybe pick your job and school district based on start times instead. I'm happy to jump on the first bandwagon that gets rid of seasonal changes to timezones.
