With the US entering Daylight-Whatever-Time this past weekend, I got to thinking. Historically, DST was implemented to save on the amount of candles used by people who followed 'clock time' instead of 'solar time'. Farmers, for example, got up when the cows needed milking, regardless of what that consarned conglomeration of gears said. Clerks, on the other hand, were supposed to be in the office in time to 'do business', regardless of where the sun was. By shifting the clocks forward and back, the clock-time was realigned with the solar time twice a year. It was somewhat convenient to do it that way, because the physical clocks only had to be messed with twice a year.
Nowadays, many clocks are set up to automagically reset to the appropriate time - I played Minecraft for an extra 7 minutes on Saturday night/Sunday morning, and ended up going to bed at three instead of two. It's a simple programming matter, as I understand it, even if you put aside the various atomic clock synchronizing apps.
So, why not distribute the hour of 'shift' across the year? Instead of the sun rising later and later in the fall, and then suddenly *bam!* we change the clocks and the morning is bright again, change the clocks a few seconds a day so that the adjustment is almost imperceptible. I think we're reaching the point in technology where this could be possible.
