I almost lost my job this morning. It’s not that my work is inadequate or anything, it’s just that I’ve shown up late the last three days. The first couple of times I slept in I assumed that I was simply sleeping through the alarm. But this morning I found out what the real problem was: my clock was losing time.
In the 21st century, this is simply inexcusable. I knew there had to be a better timekeeping contraption out there, so I did some searching online and found radio controlled clocks. These timepieces sync up with atomic clocks via satellites ensuring the most accurate timekeeping possible. Plus you won’t have to change the clocks for DST.
Obviously accuracy is extremely valuable when choosing any time piece. Clock manufacturers use different methods to insure accuracy. An atomic wall clock ‘or Radio Controlled Clock‘ updates automatically through a signal received from a radio station.
This signal ensures accuracy to within seconds of the official time. A digital atomic clock is highly accurate, but if one plans to use it in an office building with a lot of steel, the signal from the radio station may not be strong enough.
Time is a basic part of life. We use it to adhere to schedules so we can do our daily activities on time. Accurate time measurement plays an important role in many facets of our modern world. To achieve this, GPS satellites broadcast timing signals to atomic clocks or watches so that everyone all over the world can keep to agreed timetables.
It was on New Year’s Day in 1972 when the coordinated universal time was adopted as the official time for the world. The role of official timekeeper of atomic time for the world was assigned to the International Bureau of Weights and MEasures (BIPM). There are 65 laboratories with over 230 clocks that contribute to the international timescale.
An atomic clock is a type of clock that uses an atomic resonance frequency standard as its timekeeping element. They are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, and to control the frequency of television broadcasts and GPS satellite signals.
Atomic wall clocks do not use radioactivity but rather the precise microwave signal that electrons in atoms emit when they change energy levels. Early atomic clocks were masers with attached equipment. Currently the most accurate atomic clocks are based on absorption spectroscopy of cold atoms in atomic fountains such as the NIST-F1.
While we rarely take the time to notice it or even think about it, a clock’s timekeeping element is perhaps its most important component. The parts of the clock we can easily see – its face, the hands, and the design of the frame – would be basically useless without an effective method of keeping time. Some clocks, such as cuckoos and other pendulum-based types, require winding on a weekly basis just to keep time accurately.
Cuckoo clocks are often appreciated for their antique charm and the ingenuity of their inner workings. However, for those of us interested in keeping time with confidence and precision, there is no substitute for a radio controlled clock. These timepieces draw use a radio frequency to sync up with the national atomic clock. This method of time calibration is more accurate than any other that has been devised so far.
