This year will be longer than usual -- by one second, the U.S. Institute of Standards and Technology said Wednesday. The earth is sufficiently out of sync that a leap second has been scheduled for 7 p.m. U.S. Eastern Standard Time on Dec. 31, said the institute, noting those interested in watching it happen should go to www.time.gov before midnight, London time, and click on their time zone. A total of 24 leap seconds have been added since 1972, the last being in December 2005, because the...

The world's timekeepers are making the year 2008 even longer by adding a leap second to the last day of the year. The Earth is slowing down, which requires timekeepers to add an extra second to their atomic clocks to keep in sync with Earth's slightly slowing rotation.  So on December 31st at 6:59:59 p.m., an extra second will be added before 7:00 p.m. Eastern Standard Time. The extra second, plus the extra day on Feb. 29, makes the year 2008 the longest year since 1992. The decision to...

LOS ANGELES, Aug. 5 /PRNewswire/ -- If the success of American Idol(TM) has taught us anything, it is that we crave the drama and exhilaration of competitive events. "It's a remarkable communal experience that transcends borders, cultures and languages," said CEO and co-founder of Second-Look Media, Christina Tongco Garcia. "Our empathy for the struggles and hardships artists must endure to fulfill their dreams make us stand up and take notice. We hope to open doors for millions more to...

U.S. physicists have designed a new atomic clock that will not gain nor lose a second in more than 200 million years.The new precision clock was developed in the Joint Institute for Laboratory Astrophysics, a combined effort between NIST and the University of Colorado in Boulder. Another atomic clock was also created there, and both clocks are raising the standard of time."These clocks are improving so rapidly that it is impossible to tell which one will be the best," said Tom 0'Brian, head...

NEW YORK (AP) - Some physicists are creating a revolution in the arcane world of ultra-precise clocks. And among them is a researcher who has trouble getting anywhere on time. "I do tend to be a little bit late," said Jim Bergquist, 58. "Quite a bit late." Of course, the time he focuses on professionally is far removed from the world of dinner dates and planes to catch. Bergquist, who is with the National Institute of Standards and Technology in Boulder, Colo., works with extremely accurate...

If life is often a matter of split seconds - the train door that closes in your face, the chance encounter with the love of your life, the near-collision with an oncoming SUV - then the universe is about to bestow upon us a generous gift: the leap second. On Saturday, at exactly 7 p.m. Eastern Standard Time, one second will be added to our official record of time - Coordinated Universal Time, kept by a series of atomic clocks, housed in environmentally sealed vaults in about 80 timekeeping...

By Jim Wolf WASHINGTON (Reuters) - Get ready for a minute with 61 seconds. Scientists are delaying the start of 2006 by the first "leap second" in seven years, a timing tweak meant to make up for changes in the Earth's rotation. The adjustment will be carried out by sticking an extra second into atomic clocks worldwide at the stroke of midnight Coordinated Universal Time, the widely adopted international standard, the U.S. National Institute of Standards and Technology said this week. "Enjoy...

PARIS (AFP) -- Japanese scientists say they have made a technical breakthrough in the quest to perfect the world's most accurate clock, a timepiece that would lose only one-quintillionth (a million-million-millionth) of a second per day. University of Tokyo researcher Hidetoshi Katori and colleagues devised a "pendulum" of strontium atoms that ride on the crest of highly stable laser-generated lightwaves, according to their study, which appears on Thursday in Nature, the weekly British...

Cesium (or Caesium) is a chemical element with the symbol Cs and atomic number 55. Caesium is a soft alkali metal that is silvery-gold. It melts and liquefies at 83 degrees Fahrenheit and is one of only five metals that are liquid close to room temperature. Caesium is a metal that is most widely known for its use in atomic clocks. Cesium comes from the Latin word caesius meaning "˜bluish-gray'. It was discovered in 1860 by Robert Bunsen and Gustav Kirchhoff in Durkheim, Germany in mineral...
