I always hated busy work in school, and I'm hating it now as I update my home's various computers for tomorrow's daylight saving time switch, the one that our ingenious Congress decided to foist upon us.
The goal of the change in DST -- it now happens about three weeks earlier in the spring, and lasts a week later in the fall -- is to save fuel (and thus money) by giving people more daylight hours to work with. Abstractly, it makes sense. But when you get down to the fine details of actually implementing it, it's a colossal pain in the ass.
