Home Depot maintains summer/winter hours, it's not that difficult. Bin collections are by day not by time. Don't know about you but bin collections around here are "whenever they get around to your road", not at a specific hour. I used to live in the UK where trains had summer and winter schedules anyway, all published on one sheet for that line.
I can't see it being any easier to change the clocks than it would be to just do stuff at different times, if that's what you wanted to do. Mandated changes only serve to piss everyone off, let business and the voters decide when things happen locally.
