World Time Clocks – Shrinking The Globe

In these days of constant travel and global business, world time clocks are useful everywhere. It is possible to know what time it is in any time zone with this type of clock. Business travelers wanting to call home or office can find a mutually convenient time with a flick of a button. Business houses with branches all over the world, or with global associates and partners find world time clocks invaluable

There are different types of world time clocks varying with the information they can provide. Many hotel foyers and airline offices have a series of clocks that display the time at important world cities like New York, London, Paris and Tokyo. There are several fancy wristwatches that display times in two or more different cities of the wearer’s choice. While these times are not on constant display, a minor adjustment will display the time in Zurich or Canberra, while the wearer is in Mumbai.

By far the most popular world time clocks today are on the computer or Internet. There are various websites, which will give you the time in different time zones when you click on the city. In these days of rapidly advancing technology, when mobile phones, palmtops, and Blackberry instruments, multi-functional gadgets that can be carried in the pocket, world time clocks are now virtually at one’s fingertips.

The Various Uses Of World Time Clocks

It is hard to think of anybody in today’s world who has no use for world time clocks. A mother, who wants to stay in touch with her children at school far away from home, would find one invaluable. Social networking on the Internet depends on world time clocks to decide mutually convenient times for “netizens” around the globe. The entire service industry with offshore back office processing, takes advantage of time zone differences across the globe. A wife wanting to call a globe trotting husband, or friends who now live in different corners of the globe, or business associates in different continents, can prevent major blunders of time differences by referring to world time clocks.

It now seems hard to imagine a world when the only way of international communication was by what we now derisively term as snail mail. Perhaps world time clocks were only part of geography lessons in those days. All that has changed today! The world has become a global village that is getting smaller and smaller every day. The only way to keep pace with this is to stay in touch with the nearest world time clock.

Personalized Wall Clocks Provide Unique Decoration

Little could be better than looking at the time and seeing a clock that reflects a person’s favorite sport or activity, or better still personalized wall clocks with their children’s picture on the face. A family portrait staring at the room from behind the moving hands can make personalized wall clocks stand out among the decorations in the room.

However, personalized wall clocks are not only a place to hold family portraits. They can be used as tributes to a long gone family pet or a scene from their favorite vacation spot, reminding them it is getting close to the time for another visit. They can also be used to add a personal touch to a professional office, a classroom or any other location where a clock is part of the normal decorations.

Essentially, the clock is the same as many others, simply a wall clock with a different picture set behind the hands. Although they are available from many sources, with the customer buying the design of their choice, they can also be a fun, family project. By creating an appropriately size picture to fit into the clock, it be a family project to create personalized wall clocks for every room in the house, especially in the children’s bedroom.

Activities Can Reflect How They Spend Their Time

Whether the customer can use actual pictures they submit to the company or use stock photographs supplied with the clock will depend on the company from which they are ordered. Many sources offer a wide variety of choices with design geared towards many popular activities, but will welcome personalized wall clocks based on the customer’s own submission.

Many doctors and dentists that deal with children are finding personalized wall clocks with the name of the physician or dentist emblazoned on the face of the clock helps keep their patients occupied while waiting their turn in the office. Small businesses are also finding personalized wall clocks can be way to remind patrons where they are at any given time. Having the business name as well as art depicting the type of business can create a unique in-house advertising piece.

Another great use for personalized wall clocks is as gifts for the owners of small businesses. Having a clock related to their line of work that includes the business name or that of the owner, will proudly be displayed on their walls for many years. It can also serve as inspiration if they ever need to reciprocate.

Mechanical Watches

Sun, water and fire hronometricheskie devices have completed the first phase in the development of instruments for measuring time. Gradually produce a more precise picture of the time, and have sought better ways to measure it. Revolutionary invention marked a completely new stages of development in this direction was the creation of the first wheeled clock, which began with the emergence of the modern era of timekeeping.

The author and the date the invention of mechanical watches is unknown. Some reports suggest the tenth century that it was time for the first time such a mechanism built monk from Herbert Orillaka, the future Pope Sylvester II (950 – 1003). Indeed, in the technique, it was a great talent, and it had the opportunity during his study tour to get acquainted with the principles of construction of various Arab astronomical

instruments and water clock. Yet the withdrawal of the establishment of Herbert mechanical clock does not have sufficient grounds, and why.

First, the Arabs were very skilled in the manufacture of water-clock and watch Herbert also could be water. In fact, contained in documents the term «horologiya» (horologium) then treated to all sorts of devices for measuring time. Secondly, there was no further mention of the achievement of Herbert, or that his idea of someone developed during his lifetime or after it. By the way, namely Herbert introduced in Europe «Arab» figures.

Most historians see a continuity: it is, and in fact, mechanical watches are the result of complication of the mechanical part of the water, which has already been used a dial, wheel transmission mechanism for the battle, puppets, play different scenes … The difference was in force: in one case – a jet of water in another – a heavy weight. Lacking only the mechanical trigger device and control progress. Author spindle descent ( «lodge»), which at certain intervals to interrupt the movement of clock mechanism, is unknown.

Usually, historians refer to the arrangement, the drawing of which is shown in an album of French architect Villard de sinecure, as the first mentioned trigger device for the regulation of the watch: he has described (in about 1250) gross device that allowed an angel figurines are always on hand to show the sun. This mechanism, as many believe, was invented by Willard, most likely, he met with him and copy him during his travels. Besides drawing on the album Willard mechanism did not like spindle descent.

As can be seen from the sketch of this device, here as a driving force applied weight, suspended at the end of the rope, coiled around the axis of the wheel. The drop in weight and relatively uniform rotation of the vertical rod on which to stand the figure of an angel strengthened, regulated fluctuation wheel back and forth. The period of oscillations due to many factors, including the moment of inertia, friction in the bearings, the forces acting on the rope.

On the other, somewhat later, information on mechanical movement, meet at the «Divine Comedy» ( «Paradise», song X) Dante Alighieri (1265-1321):

And as a clock, where a familiar battle
Bride of Christ call us to God’s house,
Clock where well designed course,
With the sound «ding-ding» sounds like the strings on the Lira.

The song XXI «Paradise» read:

And as the clock wheels with their apparatus
So move that slightly creeping one,
Others are flying before the eyes …

But in these verses we can talk about complex water clock, rather than mechanical. Therefore, we hope to leave the definition of the author and the exact date, we have to state only one thing: someone unknown and an unknown time – probably at the end of the XIII century, invented the spindle and the progress made possible the emergence of mechanical watches. And this move was then to hand over five and a half centuries. Most same earliest date that can be reliably described, referring to the use of spindle motor hours, applies to about 1340 or later (up to several years). Since then, they quickly entered common usage and became the pride of cities and cathedrals. In 1450 there were wind-up clock, but by the end of XV century – a portable clock, but it is still too large to be called a pocket or wrist.
