Standard Time vs. Daylight Saving Time

Once again, this weekend, as we do twice a year, we had a time change. We went from Daylight Savings Time to Standard Time.  This is an artificial device to "give" us more daylight at various times of the year.  This is senseless in this day and age. We are a 24 hour society, and daylight does not so much dictate our activities as artificial time frames do.  Why do we bother?
