But what about all the little school kids waiting for the school bus in the dark some will say.
Those of you who live in the South and/or in the middle of a time zone don't realize the utility of changing the clocks because it doesn't really help you.
But if you live far north of the equator, especially in the far east or west of a time zone - you appreciate the value of the seasonal change.
Example: I live in New Hampshire - eastern part of the time zone - pretty far north. If we had year-round Standard Time, then in late May and June, the sky would get light in the morning at around 3:45am. Hard to sleep. Conversely, if we had DST all year, in late December and January, it wouldn't get light in the morning until 8:15-8:30am.
