subject: All You Need To Know About Radio Controlled Clock [print this page] In our daily life, we can't really dismiss the importance of time pieces, watches and clocks. You may stop doing anything for a day, but not time checking. These days, you don't have to depend on a watch or clock to know the time, instead, you could know the time from a mobile phone, computer or any such device. However, watches, clocks and time pieces are still in demand all over the world.
Though all these devices let us know the time, their inner design wouldn't be the same. Quartz movement is the reason behind your wall clock or your wrist watch to show the right time. One quartz crystal controls the electronic oscillator inside these clocks. Due to this quartz crystal, we are able to keep the right time. However, realize that you can still perfect your timing, for that you need to turn to radio controlled clocks.
Now let's check out what is radio controlled clocks. These clocks are specially designed in a way to receive the signal from a transmitter. When Marconi discovered the first radio in late 1800s, many people thought in the direction of radio controlled clocks. Scientists were the first few set of people who benefited from the accuracy of radio controlled clocks. They could record the time to the fraction of seconds with this new invention. There is a small radio kept in the radio controlled clocks. This radio is able to receive a radio frequency from a nearby atomic clock. Atomic clock uses an atomic oscillator, mostly calcium, which transmits the Coordinated Universal Time (UCT).
However, in the beginning, scientists only used radio controlled clocks. Their main usage of these radio controlled clocks was for laboratory purposes. Its high cost also was instrumental in making this unpopular at that time. Because of their hobby, clock enthusiasts also could keep radio controlled clocks at that time. However, these days, radio controlled clocks are affordable and anyone can have it, notably, this change has occurred during the last two decades.
If you are particular about the looks, don't worry, there are many varieties of radio controlled clocks available in the market. You can have your favorite one from the huge collection of radio controlled clocks. Digital, analogue and digital-analogue, these are the three main versions available in the market. Irrespective of the version, you will have the most accurate timing.
Also, keep in mind that radio controlled clocks wouldn't adjust the time properly after you entered a different time zone. You need to enter the time zone difference, like, 1 hour ahead of GMT, 2 hour behind GMT etc. Once set, the minutes and seconds will be accurate. In case if signals are not available, you can manually set the time on your watch. Some watches are capable of receiving signals from many transmitters all over the world, but some would receive signals only from a certain transmitter.
