Daylight saving time was observed nationally again during World War II, but not uniformly practiced until 1966, when start and end dates were standardized. States could still opt out if they wished.....But people in Hawaii and most of Arizona-- along with Puerto Rico, American Samoa and the Virgin Islands -- will do nothing come Saturday. Those locales never deviate from standard time....In 1986, the start date was moved from the last Sunday in April to the first Sunday in April.In 2005, Congress pushed the start of daylight saving time forward three weeks to the second Sunday in March, rather than the first Sunday in April, and moved the end back one week to the first Sunday in November,,,The changes went into effect in 2007 and were meant to save electricity, although a U.S. Department of Energy study estimated a savings of less than 1 percent of the countrys annual energy consumption.Among several time zone oddities, Newfoundland, Canada, has its own time zone in Canada and North America which is 30 minutes behind Eastern Standard Time. Alaska also has its own time zone.
