An Introduction to Atomic Clocks
While clocks and watches go back hundreds of years in history and are considered both old fashioned and old technology by a large number of people, the latest advancement in the world of time keeping—the atomic clock, has put these time keeping instruments on top of the high tech tables. Atomic clocks and time pieces, which use the oscillations created by an atomic system as their time keeping element, are till date the most accurate and reliable time keeping mechanism ever invented. Atomic clock times are used by scientific and standardization agencies for time keeping and form the basis for international time distribution and standardization services. Atomic clock times are also used for controlling the frequencies of GPS satellite signals and television broadcasts.
Till about a few years back, atomic clocks could be used and afforded only by government owned agencies, but thanks to advances in technology, all of us can now afford to buy atomic clocks for our homes. Atomic wall clocks are available in both online and offline stores for as little as $25 and they come in a wide variety of designs and styles to suit different decors. While earlier, only people who really needed to know the exact time till the last second used to shell out money for atomic wall clocks, many people nowadays choose to have at least one atomic wall clock in the house for two main reasons. Firstly, since atomic wall clocks nowadays cost only as much as regular wall clocks, buying one is no big deal. Secondly, with one atomic clock in the house, all the other clocks can also be manually adjusted to display the exact time.
An atomic wall clock manages to keep perfect time by automatically receiving radio signals emitted by the U.S. Atomic Clock at Fort Collins in Colorado and synchronizing its time with this clock. What this means is that your atomic wall or desk clock will never need resetting. Secondly, your atomic clock time will be accurate to within one second of the US governments official time. And this is not all, because your atomic clock time will automatically adjust to leap years, daylight saving times and changes in time zones too. It is because of this automatic setting feature that atomic travel clocks are becoming quite popular with people who have to keep moving from state to state or time zone to time zone. With an atomic travel clock, you are free from the hassles of constantly resetting your clock when you travel across time zones.
Unlike the atomic clocks kept by time keeping agencies, a home atomic clock is not costly to run either. An atomic wall or travel clock runs on a normal battery just the way all other clocks do, so buying and maintaining an atomic travel clock or house clock is similar to buying a regular clock. The only difference is that you end up reaping a number of additional advantages with an atomic wall, alarm or travel clock.
For those who want much more than just time keeping from their clocks, atomic clock manufacturers have come up with different types of time pieces with different add on features. Atomic clocks are nowadays available with a number of added features like radio and alarm etcetera. In fact, atomic dual alarm clock radios have also been introduced in the market for quite an affordable price. These atomic dual alarm clock radios not only give you the accurate time down to the last second, they also let you set dual alarms. What this means is that both you and your partner can wake up at different times to the tune of your favorite radio stations playing.
For people who are too mobile and computer dependent to ever turn to a wall clock for checking the time, but who nevertheless want to know the exact official time down to the last second, the downloadable desktop utility, the Atomic Clock Sync is a great free tool. Atomic Clock Sync automatically connects to the NIST servers every day and adjusts any existing time difference between your PCs clock and the NIST atomic clock so that your PCs clock is accurate down to the last second at any given time of the day. Since the Atomic Clock Sync is a free download, you can definitely download it if you want to get the benefits of an atomic clock without paying for one.
