>DST means that in the norther US, children can go to and from school in daylight which has public safety benefits.
You're obviously not clear on how it works. We just left DST and went to standard time. It varies by district, but around here, school hours range from 730 AM earliest start - 330 PM latest end. If kids leave for school at 7 AM, the shift to standard time means that today they're going in what was the 8 AM morning light of yesterday. It's DST which makes it darker in the mornings, and there's plenty of light in the afternoon whether DST or not.
