Read the excerpt from Eighty Years and More. With this constant [teasing] from students and the sad complaints of the women, my mind was sorely [confused]. So when, from time to time, my attention was called to these [horrible] laws, I would mark them with a pencil, and becoming more and more convinced of the necessity of taking some active measures against these unjust [laws], I resolved to seize the first opportunity, when alone in the office, to cut every one of them out of the books; supposing my father and his library were the beginning and the end of the law.

Changing the clocks does not create extra daylight, but it causes the Sun to rise and set at a later time by the clock. So, when we spring forward an hour in spring, we add 1 hour of natural daylight to our afternoon schedule. Proponents of DST argue that longer evenings motivate people to get out of the house. The main purpose of Daylight Saving Time (called "Summer Time" in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening. For some, however, the time change can have more serious consequences.  Studies link the lack of sleep at the start of DST to car accidents, workplace injuries, or  miscarriages.  The early evening darkness after the end of the DST period is linked to depression.
