Exemplary arrangements relate to a universal world timeclock, 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) sometimes 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 clocks 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 to a time across time zones, the terms of the time zone and the zone time are confused with each other. In this disclosure, a time zone describes an area oriented approximately on the geographical longitude on the earth, whereas the zone time designates the local time agreed to be applicable in the respective time zone.
Local time, world time, plus summer (e.g. daylight savings) 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 on times for 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 geographic locations such as 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. The specification of two times with identical structure, namely a local time and a world time, may distort the understanding of the actually intended time between two corresponding partners. This intuitive time calculation of a new exemplary arrangement disclosed herein requires no change in the timing of mathematics, but the international agreement or recognized designation 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.
Some 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”. If the user of the clock moves to a different time zone, the user twists the hands according to the local zone time, but takes the disk with the letters for each time zone.
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. A disadvantage of the clock disclosed there is that the clock must be adapted to the local time. Furthermore, in the Swiss patent CH 267439 it is 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 the time already has a first difficulty. Furthermore, as the last hour of the day, the symbol “Z” is used, which is misleading, because times with a “Z” usually indicate the so-called “Z”, “Zulu” time, the world time in the time zone “Z” of NATO.
An object of an exemplary arrangement is to provide a universal world time clock that provides a convenient and intuitive time display of world time.
The object of the exemplary arrangement 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 is rotatably positioned corresponding to the time zone. Further advantageous arrangements are disclosed.
According to exemplary arrangements, it is therefore provided to automatically reset a world time indication on a clock by means of a device for determining the geographic coordinates. In this case, the device for determining the geo-coordinates is connected to a table which contains the geographical boundaries of the time zones. If the device for determining the geo-coordinates has determined a coordinate, it is determined via known algorithms for determining whether the 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 which the clock is located.
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 movably positioned 24-hour dial each have unique icons comprising one letter of the Latin alphabet for each hour of the 24-hour indicators, preferably the hours 01: 00 of the current day to 0:00 of the next day have the continuous and gapless letter series 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 counting, starting at 1 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. 00: 00UTC+2 for 0:00 Central European Time, or 00:00 L for 00:00 for Local Time, 00:00 W or 00:00 Z for Time 00:00 in Zulu Time Zone 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 or in the clock, which is not changeable in relation to the world time.
In a particular exemplary arrangement, it is provided that a device for determining geo-coordinates is connected to the movement in or on the world time clock according to the exemplary arrangement, and that the movement causes the hands to move rotationally when changing the geo-coordinates corresponding to the time zone relative to the stationary oriented 24-hour clock face.
Corresponding to the dial clock (analog clock) with dial and at least one indicator or pointer such as hands, is also a digital clock as a 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 present a local time and adjusted when changing the geo-coordinates of the clock to present a local time corresponding to the time zone where the clock is currently located.
The analog clock or the digital clock can also be implemented as a clock including 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 relative to a clock face as the geographic coordinates change corresponding to the time zone. Radio-controlled clocks or clocks that derive their time from a network time signal, 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 is a time shift, or XX: XXA, where A is the time zone, does not require a geo-coordinate determination device. In these clocks, the device for determining geo-coordinates may be replaced by the computer executing an algorithm for determining the time zone from the time of the remote-transmitted wireless time signals.
The exemplary embodiments will be explained in more detail with reference to the following Figures.
According to an exemplary arrangement, a world time dial 103 rotatable relative to the stationary orientated 24-hour dial 101 is provided in the dial 100. This world time dial 103 is rotated by the clock about an axis 14 in parallel with the hands (hour hand 16, minute hand 18 and second hand 20), depending on the geographical location of the clock 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 would be on the top digit and would be at 0 on 24-hour dial 101. The world time dial 103 would be at the top with a rotational position X angularly linearly aligned with 0 on 24-hour dial 101. If the clock were now fictitiously transported to Central Europe (UTC+1 h) without any change in real time, all the hour hand 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 0 of the 24-hour dial 101 because the world time has not changed in the spatial transport. The hour hands are for the local time reading on the 1 for 01: 00, but the dials on the clocks 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
Instead of the device for determining the geo-coordinates, the computer may use an algorithm for determining the local time zone from the received information such that the computer causes a rotation of the world time dial 503 responsive at least in part to determination of the time zone.
The world time L: 00 corresponds to the time in Central Europe (UTC+1), time zone A, 13:00 A (see
For a very accurate representation in an alternative arrangement, 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
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) through 01: 00UTC+00 (A: 00) to 23:00 (W: 00).
