Description

Universal World Clock

The invention relates to a universal world time watch, comprising a movement with hands, a stationary 24-hour clock face, a clock face rotatable with respect to the 24-hour clock face with a symbol for each time zone (time zone dial) and a corresponding digital clock.

The need for a universal world time clock for international trade, for the arrangement of international telephone conferences or for the arrangement of appointments of two corresponding partners across time-zone borders has existed for a long time. To simplify the appointment, a clock with a classic dial with a circular dial, a 12-hour division and an hour and minute hands (analog clock) have smaller clocks in their dials, indicating a presettable time elsewhere in the world. Furthermore, in companies that frequently correspond with partners in other time zones, different watches are kept for major capitals of the world. It is also known to arrange international dating after World Time, the so-called UTC, "Universal Time Coordinated". Often, when agreeing time across time zones, the terms of the time zone and the zone time are confused with each other. In this case, a time zone describes an area oriented approximately on the geographical longitude on the earth, whereas the zone time designates the local time agreed in the respective time zone. Local time, world time, plus summer time introduced in different countries at different times of the year, and again at other times of the year, are causing great confusion when it comes to scheduling deadlines across time zones. Even very experienced people, such as airline pilots or frequent travelers, are often mistaken in the actual time. A particular problem is coded appointment files that are exchanged for agreeing telephone conferences with computers. Despite the availability of a universally recognized world time, the UTC, calendar dates are still being agreed in the local time of San Francisco. Corresponding computers convert the time from San Francisco into a local time.

To arrange international appointments, there is a need to use an intuitive time schedule. Because the specification of two times with identical structure, namely a local time and a world time, is already enough to distort the understanding of the actually intended time between two corresponding partners. This intuitive time calculation requires no change in the timing of mathematics, but the international agreement on how to name the world time, so that the world time is clearly, unmistakably and clearly recognizable as such. It should already be apparent from the syntax of the time specification, which time it is that use two mutually corresponding partners in the agreement of an appointment.

Approaches are already disclosed in the Swiss patent CH 267439. This patent discloses a watch which, in addition to the known 12-hour dial, has a mask with a 30 ° twisted window, each window being associated with a digit of the twelve hours of a clock. Below the twelve windows, a clockwork operates a 12-hourly rhythm dial divided into 24 sections, on which the numbers 1 to 12 and 13 to 24 are shown. This watch displays the time in 24-hour format with a 12-hour dial. Essential to the clock according to the Swiss patent CH 267439 is that the 24 hours is assigned a letter of the Latin alphabet. Starting from a time zone corresponding to the world time UTC + 2, Central European Time, a user of the clock adjusts the time 0 o'clock to correspond to a letter assigned to the time zone, there "L". Is moving the user of the clock in a different time zone, so the user twists the hands according to the local time zone, but takes the disc with the letters for each time zone with. The ratio of the local time on the stationary dial changes with respect to the movable dial. However, the absolute time, in the sense of a world time that is the same for all time zones, is retained. The example chosen in the Swiss patent CH 267439 assumed that the time M-clock corresponds to the world time noon and Z clock corresponds to the world time midnight. Disadvantage of the clock disclosed there is that the clock must be adapted to the local time. Furthermore, in the Swiss patent CH 267439 taught to name the 24 hours of the day with the letters of the Latin alphabet except "L"("local") and "W"("world"), so that in the designation of Time already gives a first difficulty. Furthermore, the symbol "Z" is used as the last hour of the day, which is misleading, because times with a "Z" usually indicate the so-called "Zulu" time, the world time in the time zone "Z". NATO.

The object of the invention is therefore to provide a universal world time clock that provides a convenient and intuitive time display of world time.

The object of the invention is achieved by the fact that in or on the world clock a device for determining geographic coordinates is connected to a device for automated rotation of the 24-hour dial, and the device for automated rotation, the 24-hour dial when changing the geographic coordinates twisted corresponding to the time zone. Further advantageous embodiments are specified in the subclaims to claim 1.

According to the invention, it is therefore provided to automatically reset a world time indication on a clock by means of a device for determining the geographic coordinates. The device for determining the geographic coordinates is connected to a table which defines the geographical boundaries of the time zones. tains. If the device for determining the geocoordinates has determined a coordinate, it is determined via known algorithms for determining whether a two-dimensional point lies within a predetermined area in which time zone the world time clock is located. Accordingly, the 24-hour dial is adjusted so that the ratio of 0 o'clock on the stationary dial corresponding to the local time is set to the world time corresponding to the time zone.

In order for world time to be intuitively recognizable as such, and even the naming of the world time clearly indicates what time is meant, it is preferred that the 24-hour dial each have one letter of the Latin alphabet for each hour of the 24-hour Tags, preferably the hours 01: 00 to 0:00 of the next day have the continuous and gapless letter from A to X in alphabetical order. It is therefore intended that the times in the 24-hour format of the time zone "Z" (Zulu) of the UTC time have the following designations:

This designation with A for 01: 00 has the advantage that the usual, starting at 1 counting is mapped to the familiar letters of the alphabet. Where X: 00 is the time on which the world day starts. The syntax of the clock notation of X: 00 over A: 00 to W: 00 is already recognizable by the syntax of the time notation even for computerized applications. The notation of other time spellings such as 00: 00UTC + 2 for 0:00 is medium European time, or 00:00 L for 00:00 for the local time, 00:00 W or 00:00 Z for the time 00:00 in the Zulu time zone of NATO well distinguishable. L: 00 is therefore the time 12:00 in the arbitrarily set UTC time and not about 00:00 L of the local time.

In order to establish a concordance between the world time and the time zones, a time zone list can be present on the clock, which is not changeable in relation to the world time.

In a particular embodiment of the invention, it is provided that a device for determining geocoordinates is connected to the movement in or on the world time clock according to the invention, and that the movement rotates the hands when changing the geocoordinates corresponding to the time zone relative to the stationary 24-hour clock face.

Corresponding to the dial clock (analog clock) with dial and pointer also a digital clock is claimed as world clock, comprising a digital display for a local time, a digital display for a world time, wherein in or at the world clock a device for determining the geo-coordinates with a digital Movement of the digital display is connected to a local time and adjusted when changing the geocoordinates the clock for a local time corresponding to the time zone.

The analog clock or the digital clock can also be implemented as a clock in a computer. The display of a computer displays an analogue clock with dial and hands. In the computer there is a device for determining the geographic coordinates, which changes a counter or a variable within the algorithm for displaying the clock so that the 24-hour dial is rotated as the geographic coordinates change corresponding to the time zone. Radio-controlled clocks or clocks that derive their time from a network, such as with the NTP protocol (Network Time Protocol) or via the GSM network or the ISDN network, thereby recognize the local time using the usual convention for specifying the time , such as UTC-x, where x stands for a time shift, or XX: XXA, where A stands for the time zone, do not require a device for determining geographic coordinates. In these watches, the device for determining geo-coordinates is replaced by an algorithm for determining the time zone from the time of the remote-transmitted time.

The invention will be explained in more detail with reference to the following figures. It shows:

1 is a dial of an analog clock according to the invention, or simulated by a computer analog clock according to the invention,

FIG. 1.1 shows a clock face of an analog clock according to the invention, or an analog clock simulated by a computer and according to the invention, rotated by a time zone hour to the east, FIG.

2 shows the display of a digital clock according to the invention, or a digital clock simulated by a computer and according to the invention,

3 shows a wristwatch according to the invention,

4 shows a digital wristwatch according to the invention, or a digital clock based on a computer,

6 shows a time zone map for explaining the time zones in contrast to world times on the basis of Latin letters,

FIG. 1 shows a dial 100 of an analog world time clock according to the invention or an analog clock simulated by a computer and according to the invention. This dial 100 has a stationary 24-hour dial 101, which serves to display the local hourly time. Furthermore, the dial 100 has another second / minute dial 202 on which both the seconds and the minutes are readable. Although it is in principle possible to divide the 24-hour dial 101 in 60 units and to use only a single dial for the local time display of the analog clock. A regular subdivision of the 24-hour dial 101 into 60 parts for 60 minutes or seconds, however, leads to an irregular structure of the graduations, because 60 is not disassembled by 24 into whole parts. For intuitive and easy reading, it is therefore intended to separate the dials for the 24 hours and for the minutes / seconds. According to the invention, a world time dial 103 rotatable relative to the stationary 24-hour dial 101 is provided in the dial 100. This world time dial 103 is rotated by the clock in parallel with the hands, depending on the geographical location and the time zone present there. For example, if the clock were at 00:00:00 local time in time zone Z (Greenwich, UK), all the hands on the top digit would be at 0. The world time dial 103 would be at the top with a rotational position X. If the watch were now fictitiously transported to Central Europe (UTC + 1 hour) without any real time, then all the hands would be on the 1 of the 24 hour dial 101. At the same time, the rotatable world-time dial 103 with the X would also coincide with the 1 of the 24-hour dial 101 because the world time has not changed in the spatial transportation. The hands are for the local time reading on the 1 for 01: 00, but remain coincident with the X for X: 00 or 00:00 UTC, or 00:00 Z.

Two corresponding partners, one of whom is based in Greenwich, UK (21: 09 Z, UTC + 0), date the watch as shown in Figure 1, and the other correspondent partner in Central Europe (22:09 A, UTC + 1), for example, these corresponding partners can arrange for a telephone conference at J: 00 the next day. For the corresponding partner in Greenwich, United Kingdom (21: 09 Z, UTC + 0), then it will be local time at J: 00, 10:00 Z. Since the Partners in Central Europe (22:09 A, UTC + 1) sees the World Time dial 103 rotated clockwise by 15 °, as shown in Figure 1.1, for the corresponding partner in Central Europe at J: 00 (1 1: 00 A , UTC + 1) 1 1: 00. The world time dial 103 represents by automatic rotation a list of concordance between local time and world time, which is also easy and intuitive to read by anyone.

FIG. 2 shows a display of a digital clock according to the invention corresponding to the world clock according to the invention, or a digital clock 200 simulated by a computer and according to the invention. While the large display 201 always represents the local time (e.g., 21:09 Z), the small display 202 always represents the unchanging world time (U: 09).

Finally, FIG. 3 shows a wristwatch according to the invention which has a dial 300 which is subdivided into a stationary 24-hour dial 301, a second / minute dial 302 and a world time rotatable relative to the stationary 24-hour dial 301 Dial 303. The watch may have a GPS receiver as a means of determining geo-coordinates and internally look up in a table which time zone is associated with the particular geo-coordinate or have a GSM module with which the watch can display both a network Time receives as well as information about the local time zone. Instead of the device for determining the geocoordinates, an algorithm for extracting the local time zone now causes a rotation of the world time dial 303.

FIG. 4 shows a wristwatch based on a computer. This wristwatch is basically a full-size computer as small as a wristwatch and simulates an analog watch having a dial 400 subdivided into a stationary 24 hour dial 401, a second / minute dial 402 and an opposite the stationary, 24-hour dial 301 rotatable world time dial 403. The wristwatch may have a GPS receiver as a device for determining the geo coordinates and internally look up in a table which time zone is assigned to the specific geocordi- nates or have a GSM module with which the watch receives both a network time and information about the local time zone. Instead of the device for determining the geocoordinates, an algorithm for extracting the local time zone causes a rotation of the world time dial 403.

Finally, FIG. 5 shows a folding computer (laptop computer) as a computer which simulates a world time clock according to the invention twice, namely once as an analog clock 500 and once as a digital world time clock 600. The same applies to the computer as to the wristwatch 4. The computer simulates an analog clock 500 having a dial divided into a stationary 24 hour dial 501, a second / minute dial 502 and a stationary 24 hour clock Dial 501 rotatable world time dial 503. The computer may have a GPS receiver as a device for determining the geographic coordinates and look up internally in a table, which time zone is assigned to the specific geographic coordinate or have a GSM module with which the computer both a Network time receives as well as information about the local time zone. Finally, location determination by the local network infrastructure is also possible, such as information from a network router connected to the computer. Instead of the device for determining the geocoordinates, an algorithm for extracting the local time zone from the received information now causes a rotation of the world time dial 503.

FIG. 6 shows a world map in which the 40 standard time zones Z, A, B, C, C *, D, D *, E, E *, E ⁺ , F, F *, G, H, H * , I, I *, K, K *, L, L *, M, M ^†† , M *, M ^† , N, O, P, P *, Q, Q *, R, S, T, U, V, V *, W, X, Y are shown. These time zones after standardized naming are invariable compared to the world time, which are divided here into the 24 hours from A to X. The similar nomenclature is the In the standard time zone Z (Greenwich, UK), the local time 00:00 Z will always be the time X: 00 and in the time zone H (Western Australia) the local time 00:00 H is always the world time H: 00. The here emerging match is not accidental, but intentional. The time of the daily change should correspond as far as possible to the local time zone, in order to support the intuition of the time measure. The standard time zones do not include a time zone L to avoid confusion with a possible misinterpretation for a local time. The world time L: 00 corresponds to the time in Central Europe (UTC + 1), time zone A, 13:00 A (see Fig. 1.1). At L: 00 it is in the time zone UTC + 12 (standard time zone Y) 00:00. In the time zone Y, therefore, the intuity is not given, the time zone Y being changed to a time zone X, W and M * due to the proximity of the date change from the areas located there.

For a very accurate representation, a standard time-zone 704 plot may also be provided on the world time dial 703, which is rotatable with respect to the 24-hour dial, as shown in Figure 7, such that the clock is also in the Nato range can be used in aviation where times are given in DTG (Date Time Group) or in standard time zones.

The universal world time clock presented here is based on the assumption of a time that is the same for all time zones. This means that a time arbitrarily chosen here as an example L: 00 o'clock in the whole world at the same time is also called L: 00. For a first person in a first location in the world, the time may be L: 00 o'clock in the morning, while the identical L: 00 o'clock for a second person in another place in the world may fall on the evening. For example, it would be possible to name the world time UTC in the 24-hour notation from 00: 00UTC + 00 (X: 00) to 01: 00UTC + 00 (A: 00) to 23:00 (W: 00). LIST OF REFERENCE NUMBERS
