The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
You change the clocks back one hour on November 6, 2011.
Atomic clock is faster than mechanical clock and it is the most accurate of all clocks in the world.
Cesium
For the simple reason that atomic clocks are highly accurate - usually only gaining or losing one second over thousands of years. High accuracy is vital in GPS systems - otherwise the maps would be out of alignment as you travelled. As an example - One of the most recent atomic clocks constructed in 2010 is reckoned to only gain or lose less than a second in over a billion years !
Any atomic clock will automatically set the time.
Yes, there are many brands of atomic wall clocks.

Digital atomic clocks keep very accurate time and good tempature, in my experience.

Digital atomic clocks should only need a new battery every two or three years.
The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
Brookstone sells self-setting alarm clocks, self-setting alarm clocks with radios, and LCD display alarm clocks with larger numbers. They also sell innovative alarm clocks such as the Tocky Rolling Alarm Clock.
Atomic clocks are in Federal Office of Metrology-Bern-Switzerland, National Physical Laboratory-Teddington-London-United Kingdom and at National Metrology Centre-Singapore. Atomic clocks are also in other countries as well.
All clocks can be compared for accuracy against the atomic clocks maintained by the US Naval observatory and National Bureau of Standards and (I beleive) the European Space Agency. Atomic clocks are almost more accurate than we can test them to be,
The Clock Depot is a dedicated site for all things clocks. From the drop down menu it shows that their product range includes grandfather clocks, alarm clocks, anniversary clocks, antique clocks, atomic clocks, carriage clocks (as indicated), cuckoo clocks, mantel clocks, nautical clocks and more.
Atomic clocks are the most accurate clocks that are available to the general public. To date, the most accurate clock made is the so-called quantum logic clock, which is accurate to about one second in 3.7 billion years.
