Digital Clock Without Electricity or Moving Parts
NerdMachine writes "Throw away those slide rules and embrace the digital age. The Digital Sundial is a 10 year old invention on display in Sundial Park (Genk, Belgium), Deutsches Museum (Munich Germany), Kölnisches Stadtmuseum (Cologne, Germany), and Martha's Vineyard, USA. You need to pivot it to adjust daylight savings time. If you can't visit one of these, Digital Sundials International can sell you one for US$12,000+, or you can buy a pocket version for under US$100 for that special nerd in your life."
Sigs cause cancer.
$12,000 USD?? That doesn't seem like a very bright idea.
.. they have built-in calculators, can be worn on the wrist, and can run a scaled-down version of Linux.

When all else fails, feel free to panic.
as in the earth. If the earth didn't rotate, it wouldn't work. Sorry, but there must be a moving part.
Sundials don't work, the one I've had in my basement hasn't changed time since I installed it.
Trolling is a art,
...will never learn to read a proper sundial.

Although the clock is set to read in 5 or 10 minute intervals, depending on the time of year it could still be up to 16 minutes fast or slow compared to your watch or clock because of the Equation of time. Our sense of time is so conditioned by our dependence on the mechanical/digital that solar time is now percieved to be "wrong".
