To measure lots of time in nanoseconds, get a longer string

[Paladin2]

Measuring time is at the base of Science.

“NIST-F2 is now an official source of time for the United States — it has an accuracy that's equivalent to about one second in 300 million years,”

What difference does it make? Mother nature changes the time with each major earthquake. The last few big earthquakes speeded up the rotation of the Earth and knocked seconds off the clock. Which means people still have to adjust clocks - even super-accurate atomic clocks.

Right 3 times a day?

From Wikipedia:

"In March 2008, physicists at NIST described a quantum logic clock based on individual ions of beryllium and aluminium. This clock was compared to NIST's mercury ion clock. These were the most accurate clocks that had been constructed, with neither clock gaining nor losing time at a rate that would exceed a second in over a billion years. In February 2010, NIST physicists described a second, enhanced version of the quantum logic clock based on individual ions of magnesium and aluminium. Considered the world's most precise clock, it offers more than twice the precision of the original."

Glad I was 0.00000000000000000000000000000001 seconds earlier otherwise I’d have been late fro my hair appointment.

I’ve got a clock on the iPad that is down to around 1/1000 of a second!

[BunnySlippers]

I want one.

[Billthedrill]

At last, a clock that can measure my period of mourning for Teddy Kennedy.

My sister owned an atomic clock and the day she died and we came home from the hospital we saw the hands go around and around really fast for 15 minutes and then reset itself at the exact right time.

Anyone know if this is something an atomic clock can do, because otherwise we assumed it was my sister saying goodbye.?

Next time, on This Old Clock....

I am mathematically challenged when it concerns time. I was taught that time is infinite and that infinity divided by anything equals infinity.

So isn’t a nanosecond infinite?

[hoagy62]

I think this is rather neat, myself. My wall clock gets the time signal from WWVB, which is now apparently tied in to the new NIST-F2. If that’s true, then I also have a very accurate clock in my own home.

[MaxMax]

I an hardly wait for the Super-Duper Atomic clock.

[a fool in paradise]

Do you still have to adjust it twice a year for Daylight Savings Time?

[a fool in paradise]

[Lazamataz]

Meh. Call me when it is available in wristwatch form.

[Organic Panic]

YET we still fart arount with stupid daylight savings time.
