| When the atomic clock is set once, it functions
within the four time zones of the continental United States only, which
will keep your atomic clock accurate to within a second over a million
years. Never will you have to reset your atomic clock again, even for
daylight-savings time, it's all done for you automatically.
Although, today different Clock manufacturers have produced
many types of Atomic Clocks the atomic principles behind them are very
similar.
There are now three main types of atoms for atomic clocks;
- cesium atoms using different levels of energy in a field of magnets.
- hydrogen atoms using a special walled container to retain the high state of energy.
- rubidium gas absorbs light, at optical frequency involving the right surrounding microwave frequency,
The most accurate and precise atomic clocks manufactured today use the cesium
atom technology.
Due to the maintenance free and perfect time precision of the atomic clocks,
they are in our books the ultimate clocks or clock to have in this day and age.
