In defense of Daylight Savings Time

In defense of daylight savings time, I had to approve the regulation that extended it for a few weeks longer every year in 2006, so I also had to read and approve the 100 page regulatory impact analysis justifying it. It was probably the best justified government regulation I worked on.

The basic idea is simple. On those summer days when the sun sets at 8pm, by symmetry, that means that sunrise is 4am. But nobody is awake then. So it makes more sense to move sunrise to 5am so the sun sets at 9pm.

There are significant electricity savings, less crime, and fewer car accidents from longer hours of daylight.
