Honestly, this comment is spot on. I think people don't realize that the fact that we are so accustomed to the 8 or 9 am meaning the start of the school or work day is not good for public health. If we had UTC or some nation wide time like China there might be more thought about when to actually start things and where the sun is actually at. The article points out that western edges of time zones are hit harder by clock changes. Other research also shows that they are in general sleeping less on western edges because the sun goes down later and they still have to get up at the same time as eastern edges. Because of this, while all-year DST would be better than what we have, it is still worse for public health than all-year standard time which is maybe worse than UTC (as people will start thinking more about the sun and maybe in 30 minute chunks instead of hours).
