Boffins build super-accurate atomic clock.

[Snetzka]

The atomic clocks currently used for regulating international time zones are great and all, but who has the time every few million years to adjust them?

Fortunately, physicists in the US have figured out how to control seemingly "forbidden" collisions between neutral strontium atoms to make a clock that neither loses nor gains a second in more than 300 million years.

Very good but my wife would drop it and break it within 15 minutes

Impressive stuff, but hardly any use for everyday purposes!
