What is the history, controversy, and clock about daylight savings time 2009?”
Daylight saving time (DST; also summer time in British English—see Terminology) is the practice of advancing clocks so that afternoons have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn.[1] Modern DST was first proposed in 1895 by George Vernon Hudson, a New Zealand entomologist.[2] Many countries have used it since then; details vary by location and change occasionally. The practice is controversial.[1] Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours,[3] but causes problems for farming, evening entertainment and other occupations tied to the sun.[4][5] Traffic fatalities are reduced when there is extra afternoon daylight;[6] its effect on health and crime is less clear. Although an early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity,[7] modern heating and co
Daylight saving time (DST) ends this Sunday, Nov. 1 at 2:00 a.m. (or — should I say 1:00 a.m.?) when we get our extra hour of morning “daylight” back. Official time turns from 1:59 a.m. back to 1:00 a.m. early Sunday morning, earning us an extra hour of sleep, and a brighter morning — though, in Oregon, I’m not sure we’ll notice. Congress passed the most recent DST revision in 2007, which sets the dates for DST: It starts on the second Sunday in March and ends on the first Sunday in November. The first daylight saving law went into effect in 1918, but no federal law actually requires states to observe the change; just, if they do, to do it at the same time as everyone else. The clock-changing time (2:00 a.m.) was selected many years ago to cause minimal disturbance to late-shift workers and train schedules. It was also selected, instead of midnight, so that DST would not cause it to all of a sudden be “yesterday,” which could be quite confusing. He who pays attention to the syntax of
