What if instead of redefining time, "Daylight saving" was the part of the year when most businesses, schools etc. started work at 8am instead of 9am? The government could mandate that schools and many other institutions change their start times, businesses could be encouraged to mostly follow (although some may choose not to if they want). Changing the definition of time is an absurd way to fix the issue. Why not have "winter miles per hour", where because more car accidents happen in winter, everyone has to adjust their car's speedometer to read 10MPH more, so that you then drive slower on the road - Roads with a 70 limit become 60, etc.
