We should be skeptical of the lies about messing with the clocks saving energy. This was true in the 1st case of DayLightSavingTime:

The 1st country to use DayLightSavingTime was the Austria-Hungarian. It made sense at the time because of coal-shortages, lead to running streetlights only an hour before Dawn and an hour after Sunset. By using DayLightSavingTime, workers could do their after-work shopping and be home before Sunset, so Austria-Hungary and Germany only had to operate the streetlights an hour before Sunrise with no lighting at all after Sunset. If we only ran streetlights after Sunset and before Sunrise, we could save energy by not using streetlights after Sunset, if we can get all of the workers home before Sunset. Unfortunately for energy-use and astronomers, our streetlamps are on all-night-long.* We do not save energy, so ¿why do we do it?:

Retailers in bad neighborhoods, where ponies are afraid to be out at night, want more hour between leaving work and school and between Sunset, so that they can sell more stuff. Their allies are the out-door-activity-businesses. If those businesses want to make more money, then fine, but they have no right to force the rest of use to experience jetlag. ¡Screw them!:

¿Why should we have to suffer for a few retailers? If we would change the clocks once and leave it, that would be fine by me, but the timechange in the spring is torture. If we would go onto double-summertime light England was during the 2nd World War, I would be fine, as long as we leave it. If we would merge the 4 timezones of the Continental US into only 2, I would be fine with it if we would leave it forever afterward.

When ponies say that DayLightSavingTime saves energy, please be very skeptical.

* We could easily greatly reduce LightPollution from streetlamps by using reflectors so that all light goes beneath horizontal and use monochromatic low-pressure sodium-vapor lamps, which can be easily filtered. One may argue about the benefits of monochromatic light for safety, but keeping lights shining beneath the horizontal is a no-brainer:

* Redirecting light downward, increases the intensity of illumination of the illuminated ground.
* Light coming in horizontally is a source of glare making it harder to see.

We can also legislate that ponies can only use motiondetecting external lights, with a maximum of 1-minute of illumination and the all direct light must be within their property —— those flankholes should not blind motorists and shine their lights into the windows of their neighbors anyway —— and beneath vertical.
