Daylight Savings Time was created to help farmers be able to extend their working and growing hours. Since the average man does not farm anymore and those that do have the advancement of modern technology it could be said that the time changing is a thing of the past. Since its no longer needed for the original creation it could become obsolete.
Daylight Savings Time doesn't serve much of a purpose anymore, and is more of a nuisance than anything else. It would be much easier to just use the same time for the whole year, instead of everyone having to remember when the time changes, and whether it goes forward one hour or back one hour. It provides a lot of headaches with no clear benefit.
Yes, I think we should no longer use Daylight Savings Time because it was enacted in a time when Daylight Savings made sense. Now, however, it has no purpose. Daylight Savings also results in many more traffic accidents in the weeks that follow because people oversleep and have to race to work.
Daylight Savings Time is a clever and useful device that should be continued. People are happier and more productive during the daylight hours, and Daylight Savings Time is a simple and effective way to increase the amount of sunshine and daylight that people experience. There may be some minor disruption for the few days after the clocks change, but that is far outweighed by the eight months of benefit each year.
