at the very least, i'd wonder if it's even remotely accurate, and even if it is, why would it matter?

@Ghen: LOL. That might be so or it might just be a coincidence. He did after all just pause the clock twice.

"A millisecond in a van is spooky" -- Racter]]>Jun 27th 2008 2:17AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Wikipedia says the average exposure time for a frame is around 1/50th of a second, so the milliseconds would be displayed about twice. The milliseconds counter does look a bit dimmer in motion, would it do this if it were moving?

Not true, some LEDs are capable of transmitting signals over 20MHz, or 20 million updates a second. Even basic LEDs (like those used in household remote controls) can be updated 50 thousand times a second.

Matt:

The milliseconds digit looks dimmer even when the time is paused. It could be a variation in the power supplied to each digit. Off the shelf resistors and capacitors have variations of several percent.]]>Jun 27th 2008 8:52AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Jun 27th 2008 10:00AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/There is a big difference between "LED" and "display".

They took the clock, syncronized it to another one, and put it on a fast jet that can fly around the world.

After the plane flew around the world they checked the clocks, and they were off by a fraction of a second.]]>Jun 27th 2008 2:28AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Jun 27th 2008 2:53AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Jun 27th 2008 2:55AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Jun 27th 2008 2:58AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Jun 27th 2008 3:04AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Jun 27th 2008 3:42AMhttp://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/http://www.engadget.com/2008/06/27/fastest-clock-in-the-world-tells-time-to-the-microsecond/Einstein didn't do this experiment.
