All these separate proposals are a logical nightmare for truckers and people who have to cross state lines. I've heard this proposal before, but seems way simpler:
1) Abolish daylight savings and the 1 hour change and keep things the way they are. So technically daylight savings is right now (from March-Oct). Just keep it as it is this very second
2) Merge the Pacific time zone with Mountain time zone. That way in the continental US we have 3 time zone: Eastern, Central, and Mountain
But I can't find the exact resource I got this idea from, but I think this would minimize the headaches and gripes people have.
