RADIO CONTROLLED CLOCKS | WATCHES

For many years man has been obsessed with the recording of time, from the first sundials to the elaborate gear driven pieces which were later developed. There arose a need for a device which would have an unequaled accuracy for the measure of the units of time. A device which would not fall prey to such trivial things as clouds covering the sun in the sky or faulty mechanisms which fall prey to degradation of use over time. This device would later be invented and called The Atomic Clock.

Thru many years of testing and development for a new and much more reliable way of time keeping, arose the Atomic Clock developed by the National Bureau of Standards in 1949. Using the ammonia molecule as its source for the progress of time. Thus resulted the beginnings based on the ideas of Isidor Rabi, unfortunately at the time of its creation the accuracy was just a little above par of the existing time keeping devices of its day.

In 1957, arose the new and improved version of the Atomic Clock using the cesium atom, after the first model another was created using the same atomic choice. Later in 1960 the accuracy was so improved that the results were adopted by the National Institute of Standards and Technology for the keeping of time.

In 1967 the cesium atoms accuracy was recognized internationally for the measure of the unit of time. Much of our modern life has now come to depend of these creations from the beginnings of the atomic age. The Atomic Clock forms the basis for the time keeping of the world, our transportation, communication, computers, and power facility’s all use the Atomic clock to one degree or another.

In this day and time what would our life be like without the accuracy of the Atomic Clock, for its uses are unrivaled by any other time piece thus created, thru its many revisions over time it has become more accurate and steady, as years go by many improvements have come about and many will still to come for as in the beginnings to the now and present, we will always seek to improve upon our methods for recording to the benefits of all.

The Radio Controlled Clocks is one of the top clocks found today. This device would later be invented and called The Atomic Clock

So what exactly does is the atomic clock? The atomic clock is a clock that uses the atomic resonance frequency standard as its own time keeping element. These time and frequency standards are the most accurate that we know. This time is used as the standard for international time services such as television broadcast or global positioning systems.

Although it may sound like it, these kind of clock does not use any type of radioactivity. It actually uses very precise microwave signals that are emitted by electrons within atoms as the energy levels change.

So what difference does the atomic clock make?

Everyday a tiny bit of time is lost. This is actually only microscopic bits of time that would make no difference in the immediate future. However, left unguarded this time would eventually add up. Although it may take quite some time there would be a great loss of time consistent standards across the globe. This may seem like small stuff, but the fact is that airports, television, radio, train scheduling and many other important aspects are controlled by the time of the this clock.

When it is your plane departing or the train you are embarking in you would want to know that the timing in the air or on the ground at train switch houses is all set to one single standard. This is the purpose of the atomic clock. Although it seems a small matter, it is one that creates a lot of the safety we have grown to trust in. Because of the atomic-clock planes and trains do not collide mid trip when precision in timing can be a life or death matter.

These are the most serious examples but there are a lot of smaller ones that are important to many people as well. The New York Stock Exchange is run on very strict time deadlines. With millions of dollars being earned and lost each and every minute on the NYSE you would not be able to convince any stockbroker there that the few seconds per year we may lose without the power of the atomic clock are unimportant.

Buying Atomic Clock is somewhat great to investment, but you have to make sure that it’s Accurate Clocks to buy.

For over many centuries, sailors and explorers strove to find a system that would accurately tell them their position and also to avoid dangers and accidents while on voyages. In the year 1993, with the invention of GPS, a 24-satellite network, the most viable solution to this problem was reached. Today, GPS systems are affordable at just few hundred dollars and have proved to be of great help to mankind. The GPS technology in turn, derives its efficacy, power, and accuracy from the atomic clock. This clock is precise to one billionth of a second. The atomic clock was conceived on the assumption that the magnetic resonance of atomic beams can be used to calculate time. The precision that was achieved by calculating time thus went on to enhance the functionalities of the Global Positioning System. The makers of the atomic clock probably did not fathom that their creation would have such far-reaching effects.

Atomic clock uses an “atomic resonance frequency standard” for accurate time keeping. You must however, remember that the principles on which this clock works is not based on nuclear science, as the name suggests, but on precise microwave signals. The early atomic clock was powered by MASERs – Microwave Amplification by Stimulated Emission of Radiation; the modern-day version is driven by absorption spectroscopy of cold atoms placed in atomic fountains.

Because of their accuracy, these clocks (made of ceasium or rubidium) are used onboard a space shuttle with GPS satellites. Time is calculated to within about 50 nanoseconds and then mathematically transformed into three absolute coordinates of space and one coordinate of time. These precision GPSs are also used in computer networks, scientific laboratories, and in many forms of communication systems. They are used by airliners to navigate while ships use this system to find their way safely across oceans. They are also used by emergency medical vehicles to find their way through the maze of streets in a big city. Today this system is used to detect abnormal rumblings inside the bowel of the earth and issue earthquake alerts.

An atomic clock can be bought from online stores at attractive rates. But you must be very careful when buying such a clock; do not fall for discounted prices only. A genuine atomic clock should be accurate to a nano-fraction of a second. So when buying, check that the clock is giving such precise times.

Who does not have a few clocks in his or her home? Everyone needs them and we all use them each and every day of our lives. There are many different kinds of and most of us own several. There are many different clocks, wall, grandfather, the ever popular alarm and, of course, my personal favorite Coldplay. Clocks are simply a part of our lives the whole world round, there is even a world clock and an atomic clock. We just cannot escape these infernal, yet useful machines.

The history of clocks goes far back into the past of humans. The sun dial was an early form, it was a rather rudimentary design but it was accurate and it worked for people back then. Now of course we are even busier and we need to be more precise about everything that we do. We are always rushing off to somewhere and without clocks we would not be able to get there in time. In fact it seems as though time runs our lives these days.

Wall clocks are a great addition to any room in your home. They are attractive and they do not take up any floor space. Most of us are lacking in the floor space that grandfather clocks need so we make do with wall clocks.

Wall clocks are also nice because they are easy to make room for. They come in all different shapes and sizes, which make them perfect for squeezing in on even a busy and full wall. Wall clocks look great in any home with any décor. There are all kinds that are plain enough to match anywhere in any room. These are the most popular of all and thankfully the least expensive as well.

You can find some pretty exciting looking clocks as well. If you like to make a statement then you will want to choose ones that are a little different from the everyday. This means looking to clocks that are perhaps bright and colorful or even large and full of fantastic art forms. Strange and unusual shaped ones are a big hit as well and your home could definitely benefit from these.

Grandfather clocks are something that many people have had passed down to them from past generations in their family. Other people go searching for them. These are some of the most fantastic and glorious clocks in the whole world.  They are generally large, though how large may differ from one examplt to the next.

Some of the best grandfather clocks are the older generation. These can be found in antique stores or online auctions and they are generally very expensive. In fact, all of them tend to be quite expensive but they are always well worth the money that you spend on them. They make wonderful heirlooms for you to pass down in your own family. This is a clock that your great grandchildren will feel honored to receive down the line.

Network Time Protocol is an Internet protocol used to synchronize computer clocks to a stable and precise time reference. NTP was originally developed by Professor David L. Mills at the University of Delaware in 1985 and is an Internet standard protocol.

NTP was developed to solve the problem of multiple computers working together and having the different time. Whilst, time usually just advances, if programs are running on different computers time should advance even if you switch from one computer to another. However, if one system is ahead of the other, switching between these systems would cause time to jump forward and back.

As a consequence, networks may run their own time, but as soon as you connect to the Internet, effects become visible. Just Email messages arrive before they were sent, and are even replied to before they were mailed!

Whilst this sort of problem may seem innocuous when it comes to receiving email, however, in some environments a lack of synchronisation can have disastrous results this is why air traffic control was one of the first applications for NTP.

NTP uses a single time source and distributes it amongst all devices on a network it does this by using an algorithm that works out how much to adjust a system clock to ensure synchronisation.

NTP works on a hierarchical basis to ensure there are no network traffic and bandwidth problems. It uses a single time source, normally UTC (coordinated universal time) and receives time requests from the machines on the top of the hierarch which then pass the time on further down the chain.

Most networks that utilise NTP will use a dedicated network time server to receive their UTC time signal. These can receive the time from the GPS network or radio transmissions broadcast by national physics laboratories. These dedicated NTP time servers are ideal as they receive time direct from an atomic clock source they are also secure as they are situated externally and therefore do not require interruptions in the network firewall.

Network Time Protocol (NTP) is a TCP/IP protocol developed when the internet was in its infancy. It was developed by David Mills of the University of Delaware who was trying to synchronise computers across a network with a degree of precision.

NTP is a UNIX based protocol but it has been ported to operate just as effectively on PCs and a version has been included with operating systems since Windows 2000 (including Windows 7, Vista and XP).

NTP, and the daemon (application) that controls it, is not just a method of passing the time around. Any system running the NTP daemon can act as a client by querying the reference time from other servers or it can make its own time available for other devices to use which in effect turns it into a time server itself. It can also act as a peer by collaborating with other peers to find the most stable and accurate time source to use.

One of the most flexible aspects of NTP is its hierarchical nature. NTP divides devices into strata, each stratum level is defined by its proximity to the reference clock (atomic clock). The atomic clock itself is a stratum 0 device, the closest device to it (often a dedicated NTP time server) is a stratum 1 device whilst other devices that connect to that become stratum 2. NTP can maintain accuracy to within 16 stratum levels.

Any network that needs to be synchronised, has to first identify and locate a time source for NTP to distribute. Internet sources of time are available but thee are often taken from stratum 2 devices that operate through the firewall. The only way NTP can peer the time is if the TCP/IP port is left open to allow the traffic through. This could lead to security issues as malicious users can take advantage of this firewall hole.

Dedicated NTP time servers find a source of time via GPS or radio signals and so don’t leave a network vulnerable to attack. By attaching a NTP time server to a router and entire network of hundreds and even thousands of devices can be synchronised thanks to NTP’s hierarchical structure.

In the evolution of watch and clock making, mechanical clocks became the foundation upon which other types of watches and clocks were made. The theory that a mechanical mechanism could “tick” of time in specific, set increments is the basis of both the quartz watch and the atomic clock.

The Quartz Watch

The Americans, Swiss and Japanese all played a part in the invention of the quartz watch. One of the first quartz watches ever built for mass market distribution was made by the Sinclair Company.  It had the right idea, using quartz crystals to complete an electrical circuit that would move a mechanical movement in precise increments, but the outer casing and primitive use of the quartz proved disastrous.

Sinclair’s “Black Watch” was a digital model quartz watch that was introduced in 1975.  It had all kinds of problems from losing or gaining time during the changes in hot and cold weather to creating static that would affect its time keeping abilities simply by walking on nylon carpet or having static due to clothing or air conditioning.  In addition, it had a battery that could only hold a charge for 10 days.  There appeared to be as many returns of this watch as there were sales!

The quartz watch was still a desirable option to explore and many other companies had models of digital quartz watches in the experimental stages and ready to sell.  However, the reliable early quartz watches were still about $125 or more — very expensive for the mid-1970s.  These newer, more expensive watches were at least able to keep good time. In fact all well-made quartz watches kept very accurate time and in 1976 Texas Instruments introduced a model at the Chicago Consumer Electronic Show that could be produced in mass quantities for a mere $20.  

The makings of a quartz watch started with the first watch battery in 1954.  Next came the development of the integrated circuit in 1959.  With light-emitting diodes (LED)being developed around 1962, all of the elements were in place for a digital quartz watch.  In fact, the very first prototype, the Beta 21, came out in 1967.  The development of liquid crystal displays (LCD) in 1968 gave digital watches the look they have today. Pulsar is credited with creating the first digital watch in 1970.

The Atomic Clock

Universal time is measured by an atomic clock which runs by using the element, cesium, to keep it going. Just one gram of cesium is enough of a “fuel” to run an atomic clock for one year.  Cesium is found in granite and the one gram supply can be extracted from a piece of granite that is about a cubic foot in size.

This silvery metal is in liquid form at room temperature and is considered the most electropositive and alkaline element in the periodic table.  It is used as a catalyst in photoelectric cells to react with hydrogen and create the necessary movement of the atoms which create a microwave frequency and natural resonance to define a single second. This cycle used to measure a second is actually made up of exactly 9,192,631,770 oscillations of the cesium atom’s resonant frequency.

Of course the atomic clock is not the type of clock one keeps in their home, but it is the national standard for keeping time in America.  For home use, today’s quartz clocks and watches offer a highly precise way of keeping time.

Time synchronisation in modern computer networks is essential. It not only provides the only frame of reference between all devices, it is critical in everything from securing, planning and debugging a network to providing a time stamp for applications such as data acquisition or email.

Microsoft Windows XP has a time synchronisation utility built into the operating system called Windows Time (w32time.exe) which can be configured to operate as a network time server. It can be configured to both synchronise a network using the internal clock or an external time source.

For many applications, an internal clock can be quite adequate, although, on a network, problems can arise with applications such as sharing network files or in some environments even fraud, so it is vital for security reasons to use an accurate timing source for your network.

NTP (Network Time Protocol) is a protocol already installed on Windows XP and is used by Windows Time to keep machines synchronised to the single time source. There are several timing sources available on the Internet but Microsoft and others strongly recommend that you configure a time server with a hardware source rather than from the Internet where there is no authentication.

Specialist NTP servers are available that can receive a reliable time source via the GPS signal or specialist radio transmissions that get their time from Atomic Clocks.

If you wish to configure Windows XP to operate as a time server then first thing is to locate the Windows Time subkey. To do this:

Run Regedit (Click start/run/then type REGEDIT/and click enter.

Note: editing your system registry can cause problems with your system. It is advisable to back up your system before editing the registry.

Locate this subkey:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpClient

Right-click in the right-side window and Modify. Edit the DWORD value box and type the number of seconds you want for each poll under Value data, i.e.: 900 will equal 15 minutes. The poll field represents the polling interval between NTP poll packets.

To enable the NTP server locate the subkey: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpServer

Right click enabled (in the right-hand window) then Modify. Edit the DWORD Value and type 1. Right-click NtpServer, then Modify and in the Edit DWORD Value under Value Data type Peers, then click OK.

The idea of atomic watches sounds a little exciting, doesn’t it? Well, it may sound more exciting than it really is. The atomic watch will not blow up either. Actually, the atomic watch acts as both a radio wave receiver and a quartz watch. When the atomic watch cannot receive the time signal, it reverts to a quartz watch so that the wearer does not track of the correct time for long.

As a radio wave receiver, the wristwatch is able to keep the most accurate time according to the atomic clock of the country in which it is intended to be used. For instance, the American atomic watches will receive a low frequency radio signal from the U.S. atomic clock located in Colorado. European atomic watches will keep time according to the European country in which it was purchased. An American watch would not work in a European country because of the difference in transmitter frequency.

Within the watch case of an atomic watch, there is a small antenna. The small antenna receives the time broadcast from the atomic clock. In this way, the watch will provide the most accurate time because it will be in synch with the country’s atomic clock. The atomic clock is powered by a battery or solar energy. When the battery is changed, the watch will set itself when it begins to receive the signal again. There is no need to rewind the watch.

Atomic watches will be the most accurate watch in any country in which the watches are worn. When a wearer travels out of the country, the watch will no longer receive the radio signal. At this time, the watch will switch over to a regular quartz watch. When the traveler goes back to their home country and the watch receives the time signal again, the watch will display the time according to the atomic clock in their country. If the you travel through the different time zones of your home country, you will be able to manually adjust the time zone on the watch to coordinate with the time zone in which you are located.

Atomic watches are constantly searching for their frequency in order to stay accurate. Sometimes, interference from a strong electrical field or blockage from a large building may shield the watch so that it does not receive the radio signal. If this happens, the watch will continue running from its last positive signal so that the time will remain correct. This means that you will not lose your accurate time even if you have temporarily lost the radio time signal.

As a radio receiver, atomic watches provide great accuracy for time and even style. Atomic watches are available for men and women in a variety of colors and sizes. You can find atomic watches made of plastic, rubber, stainless steel and other metals that are suitable for any budget. The accurate time provided by atomic watches marks this watch as the right watch for any time.
