Tonight at 2am, remember to set your clock an hour forward. Look forward to both more sunlight at the end of the day and unfortunately, an earlier rise to work. Wikipedia explains why:

Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours, but causes problems for farming, evening entertainment and other occupations tied to the sun. Traffic fatalities are reduced when there is extra afternoon daylight;[6] its effect on health and crime is less clear. Although an early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity, modern heating and cooling usage patterns differ greatly, and research about how DST currently affects energy use is limited and often contradictory.

Emphasis on energy usage, all mine, to match my surprise. I did not know that. Did you?

Oh, apparently Wilson did. And the energy savings are BS these days, say some. So remind me why we still use this system? [Wiki]
