Chinese atomic clock given international recognition
By Digital Content

BEIJING, Aug 22 (Xinhua) -- A Chinese atomic clock has been accepted by international authorities as a primary basis for high-precision international atomic time, announced the National Institute of Metrology (NIM) on Thursday.

The cesium atomic clock, known as NIM-5 and developed by the institute, is a kind of extremely accurate time-keeping device. It can be accurate to within one second over 20 million years, according to Chinese media.

The nod from the Paris-based Bureau International des Poids et Mesures, the authority for international time and frequency standards, has made China the eighth country to calibrate the international atomic time, after France, the United States, Germany, Italy, Japan, the UK and Russia.

Insiders said the clock could define a Chinese atomic time independent from GPS signals or other international time-keeping data. (Xinhua)

This was possible only because the Chinese agreed to file-off the Bolex engraving.

I wonder how they synchronise all 8? Relativity, and all that.

Wake me up when it's Won o'clock. Might order chinese food.

one second in 20 million years ? How did they test that?

Now if only they could obtain similar accuracy with some of the other rubbish they are pumping out into the world.

So it's" is a kind of extremely accurate time-keeping device."

And " Insiders said the clock could define a Chinese atomic time"

Very precise scientific research and reporting......not

one second in 20 million years ? How did they test that?

With a clock even more accurate?

one second in 20 million years ? How did they test that?

With a clock even more accurate?

Years ago I bought a Rolex for 500 baht at the markets, it's deadly accurate.....maybe they borrowed that and I didn't notice.

I wonder who started the testing Procedure 20 million years ago and how do they know what time he started the test. FACINATING.

one second in 20 million years ? How did they test that?

Now if only they could obtain similar accuracy with some of the other rubbish they are pumping out into the world.

How about that it lost one twenty millionth of a second in a year?

Or it gained one 40 millionth of a second in the last 6 months?

Mmmmmmm .

You live in a strange world seas........ how could anyone move their hand on the stopwatch, so quickly ?

My idea is much more plausible

I'm guessing the Chinese version is an alarm clock.

Just wait until it goes bang.

No refund.

What, without an attached two-slice toaster and drip coffee machine--c'mon, man, who'd buy THAT?
