Look, lets just give everyone a pair of night vision goggles – this would eliminate the need for daylight altogether. Think of all the implications – provide a boost to our military industrial complex, save electricity, cut pollution the benefits are endless.

Here’s some wiki on DST:
Daylight saving time (DST; also, summer time in British English; see Terminology) is the convention of advancing clocks so that afternoons have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. Modern DST was first proposed in 1907 by the English builder William Willett. Many countries have used it since then; details vary by location and change occasionally.

The practice is controversial.[1] Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours,[2] but causes problems for farming, entertainment and other occupations tied to the sun.[3][4] Traffic fatalities are reduced when there is extra afternoon daylight;[5] 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,[6] modern heating and cooling usage patterns greatly differ, and research about how DST currently affects energy use is limited and often contradictory.[7]

DST’s occasional clock shifts present other challenges. They complicate timekeeping and can disrupt meetings, travel, billing, recordkeeping, medical devices, and heavy equipment.[8] Many computer-based systems can adjust their clocks automatically, but this can be limited and error-prone, particularly when DST rules change.[9]

But that’s beside the point. At this point in our world, DST is pointless. I live in AZ where we dont have it, and other than the inconvenience of dealing with everyone else who does, we much rpefer it that way.
