British custodians of time prolong 2008 gloom with 'leap second'


10...9...8...7...6...5...4...3....2....1.....1....Can't wait to kiss the worst economic year to hit the planet since the great depression good-bye? You'll have to wait a second.

That's because the British custodians of time are preparing to tack a "leap second" onto the clock Wednesday to account for the minute slowing of the Earth's rotation - meaning champagne toasts, Auld Lang Synes and of course, that kiss, will have to come a second late.

The leap second has been used sporadically at the Royal Observatory at Greenwich since 1972, an adjustment that has kept Greenwich Mean Time the internationally agreed time standard.

Some scientists now say GMT should be replaced by International Atomic Time - computed outside Paris - because new technologies have allowed atomic time to tick away with down-to-the-nanosecond accuracy.

But opponents say atomic time's very precision poses a problem.

A strict measurement, they say, would change our very notion of time forever, as atomic clocks would one day outpace the familiar cycle of sunrise and sunset.

The time warp wouldn't be noticeable for generations, but within a millennium, noon - the hour associated with the sun's highest point in the sky - would occur around 1 o'clock. In tens of thousands of years, the sun would be days behind the human calendar.

That bothers people like Steve Allen, an analyst at the University of California at Santa Cruz's Lick Observatory.

"I think (our descendants) will curse us less if we choose to keep the clock reading near 12:00 when the sun is highest in the sky," Allen said.

Atomic time advocates argue that leap seconds are onerous because they're unpredictable.

Since the exact speed of the Earth's rotation can't be plotted out in advance, they're added as needed. Sometimes, like this year, they're added on Dec. 31, sometimes they're inserted at the end of June 30.

Those willy-nilly fixes can trip up time-sensitive software, particularly in Asia, where the extra second is added in the middle of the day.

Critics say everything from satellite navigation to power transmission and cellular communication is vulnerable to problems stemming from programs ignoring the extra second or adding it at different times.

When the extra second is added, the National Institute of Standards and Technology in Boulder, Colo., which provides the time standard for computers and appliances across the United States, will probably be busy fixing bugs starting at 5 p.m. Mountain Time, predicted Judah Levine, a physicist at the institute's Time and Frequency Division.

"There's always somebody who doesn't get it right," Levine said. "It never fails."

Britons seemed less concerned about the remote prospect of having tea at 3 a.m. than the notion of leaving a France-based body in control of the world's time.

"I think there's some kind of historical pride we might feel in Britain about Greenwich being the point around which time is measured," 50-year-old telecoms executive Stephen Mallinson said as he waited to board a Eurostar train for Paris at London's St. Pancras Station.

"But in practice, does it make a difference? No."

At the Royal Observatory, 53-year-old homemaker Susie Holt was adjusting her wristwatch to match the digital display above the meridian. She said it would be a pity if GMT were made obsolete. Her daughter, 15-year-old Kirsty, was more forthright.

"We don't want the French to control time," she said. "They might get it wrong or something."

Meanwhile, Elisa Felicitas Arias, a scientist at the International Bureau of Weights and Measures, which computes atomic time at a facility outside Paris, has been busy lobbying to scrap the leap seconds that have given the 17th century Royal Observatory pride of place.

"GMT is out of date," she sniffed.

She said she has been garnering considerable support, with the International Telecommunications Union - the arbiter of international time standards - considering a vote on a switch as early as next year, with a 2018 target to implement it.

The U.S., France, Germany, Italy, and Japan were all on board, she said.

But David Rooney, the Royal Observatory's curator of time, defended leap seconds, saying they give everyone "the best of both worlds."

The arrangement, he said, allows satellites, physicists, and high-frequency traders to benefit from the accuracy of atomic time while keeping our clocks consistent with the position of the sun in the sky - and with GMT.

The American Astronomical Society is officially neutral on the proposal to switch to atomic time, which is calculated based on readings from more than 200 atomic clocks maintained across the world.

Perhaps predictably, Britain's Royal Astronomical Society has come out in favour of conserving leap seconds. While spokesman Robert Massey said star-watchers could cope no matter what happened, he urged caution on such an important change.

"It's not just a matter for the telecommunications industry to tell everybody to get rid of the leap second," Massey said. "It would be a big cultural change at the very least. Abandoning the connection between time and solar time is really a big shift."

HAPPY NEW YEAR!!!!!


Well it's another year....

But for what reason??


"Happy New Year!" That greeting will be said and heard for at least the first couple of weeks as a new year gets under way.

But the day celebrated as New Year's Day
in modern America was not always on January 1st.

ANCIENT NEW YEARS The celebration of the new year is the oldest of all holidays. It was first observed in ancient Babylon approximately 4000 years ago. In the years around 2000 BC, the Babylonian New Year began with the first New Moon (actually the first visible cresent) after the Vernal Equinox (first day of spring).

The beginning of spring is a pretty logical time to start a new year.
After all, it is the season of rebirth, of planting new crops, and of blossoming. January 1, on the other hand, has no astronomical nor agricultural significance. It is purely arbitrary.

The Babylonian new year celebration lasted for eleven days. Each day had its own particular mode of celebration, It's safe to say that modern New Year's Eve festivities pale in comparison.

The Romans continued to observe the new year in late March, but their calendar was continually tampered with by various emperors so that the calendar soon became out of synchronization with the sun.

In order to set the calendar right, in 153 BC, the Roman senate, declared January 1 to be the beginning of the new year. But tampering continued until Julius Caesar, in 46 BC, established what has come to be known as the Julian Calendar. It again established January 1 as the new year. But in order to synchronize the calendar with the sun, Caesar had to let the previous year drag on for 445 days.

THE CHURCH'S VIEW OF NEW YEAR CELEBRATIONS
Although in the first centuries AD the Romans continued celebrating the new year, the early Catholic Church condemned the festivities as paganism. But as Christianity became more widespread, the early church began having its own religious observances concurrently with many of the pagan celebrations, and New Year's Day was no different. New Years is still observed as the Feast of Christ's Circumcision by some denominations.

During the Middle Ages, the Church remained opposed to celebrating New Years.
January 1 has been celebrated as a holiday by Western nations for only the past 400 years (give or take).


NEW YEAR TRADITIONS
Other traditions of the season include the making of New Year's resolutions.

That tradition also dates back to the early Babylonians. Popular modern resolutions might include the promise to lose weight or quit smoking. The early Babylonian's most popular resolution was to return borrowed farm equipment to there rightful owners.


The Tournament of Roses Parade, dates back to 1886. In that year, members of the Valley Hunt Club decorated their carriages with flowers. It celebrated the ripening of the orange crop in California.

Although the Rose Bowl football game was first played as a part of the Tournament of Roses in 1902, it was replaced by Roman chariot races the following year. In 1916, the football game returned as the sports centerpiece of the festival.


The tradition of using a baby to signify the new year was begun in Greece around 600 BC. It was their tradition at that time to celebrate their god of wine, Dionysus, by parading a baby in a basket, representing the annual rebirth of that god as the spirit of fertility. Early Egyptians also used a baby as a symbol of rebirth.

Although the early Christians denounced the practice as pagan, the popularity of the baby as a symbol of rebirth forced the Church to re-evaluate its position. The Church finally allowed its members to celebrate the new year with a baby, which was to symbolize the birth of the baby Jesus.


The use of an image of a baby with a New Years banner as a symbolic representation of the new year was brought to early America by the Germans.
They had used the effigy since the fourteenth century.

FOR LUCK IN THE NEW YEAR
Traditionally, it was thought that one could affect the luck they would have throughout the coming year by what they did or ate on the first day of the year. For that reason, it has become common for folks to celebrate the first few minutes of a brand new year in the company of family and friends.

Parties often last into the middle of the night after the ringing in of a new year. It was once believed that the first visitor on New Year's Day would bring either good luck or bad luck the rest of the year. It was particularly lucky if that visitor happened to be a tall dark-haired man.

Traditional New Year foods are also thought to bring luck. Many cultures believe that anything in the shape of a ring is good luck, because it symbolizes "coming full circle," completing a year's cycle. For that reason, the Dutch believe that eating donuts on New Year's Day will bring good fortune.

Many parts of the U.S. celebrate the new year by consuming black-eyed peas. These legumes are typically accompanied by either hog jowls or ham. Black-eyed peas and other legumes have been considered good luck in many cultures. The hog, and thus its meat, is considered lucky because it symbolizes prosperity. Cabbage is another "good luck" vegetable that is consumed on New Year's Day by many. Cabbage leaves are also considered a sign of prosperity, being representative of paper currency. In some regions, rice is a lucky food that is eaten on New Year's Day.

AULD LANG SYNE
The song, "Auld Lang Syne," playing in the background, is sung at the stroke of midnight in almost every English-speaking country in the world to bring in the new year.
At least partially written by Robert Burns in the 1700's, it was first published in 1796 after Burns' death. Early variations of the song were sung prior to 1700 and inspired Burns to produce the modern rendition. An old Scotch tune, "Auld Lang Syne" literally means "old long ago," or simply, "the good old days." Can't remember the words? The lyrics can be found here.
