This is providing that my Atomic Clock is correct.
Clocks that do not lose time
Scientists have developed laser clocks that can keep time without missing a beat in nearly two billion years. They are so precise that
they could lead eventually lead to automated cars.

Video: New Atomic Clock Reaches A 100 Quadrillionth Of A Second Accuracy
by Serkan Toto From TechCrunch.com
A team of researchers at the University of Tokyo has developed a new type of optical atomic clock that boasts a 100 quadrillionth of a second accuracy (one quadrillion has 15 zeros). The optical lattice clock is the brain child of Professor Katori who says his device observes a million atoms simultaneously whereas conventional atomic clocks measure time by using single atoms.
The Professor explains:
“(…) if one clock is placed one centimeter higher than another clock, the higher clock is affected by less gravity, so it goes faster. That difference could be read out in the 18th decimal place of the clocks in one second averaging time. Until now, clocks have been thought of as tools for sharing a common time. But with clocks like this, conversely, we can understand that time passes at different speeds, depending on the time and place a clock is at.”
The idea is to eventually use the new clock to improve GPS (which is based on atomic clocks delivering 14-or 15-digit accuracy) or to predict earthquakes, for example.

Twisted Design: Telling Time With Toys and Bluetooth
Who knew that watching a clock work could be so hypnotizing? The Tilted Twister clock from Hans Andersson is composed of two Lego Minstorm bricks connected by Bluetooth. The master brick is in charge of tracking the time and operating the minute digits. The slave brick is responsible for moving the seconds indicator and the hour digits.
Watching the time change ever so slowly from one minute to the next is a surprisingly entertaining venture. The digits all consist of five layers of black and white tiles. The tiles are twisted around by the top layer until they form the appropriate digit.
Staring at the video of this awesome clock is one thing, but it’s so loud that it would probably be a huge pain to live with. Still, it might be worth the irritation just to have such a unique and artful timepiece keeping you grounded in reality.
