I agree permanent standard time is a better solution. But maybe we change work to 8-4 from 9-5 and might be better that way anyway.
Why not change the working hours of stores, and tv programming and other schedules too?
In the end, you get the same thing as a clock change, but having to change the times of everything everywhere.
Stores already open across a spectrum of times.
(It's actually 8-5 with an hour's break).
