Daylight Saving Time

[摘要] Currently, in most parts of the United States, timepieces are moved forward one hour in the spring and back one hour in the fall to provide an extended daylight period during the summer months. This is known as Daylight Saving Time (DST). Much debate and many changes led to this present practice. This report provides a brief history of the issues surrounding DST, an outline of the legislation that created and modified it, and a list of references to more discussions.
