Definitions

  • an international time indicating system is associated with a telephone, calculator, computer, software package, integrated circuit, real time clock or the like for automatically displaying a specific time and date of a called place.
  • the international time indicating system comprises means for entering or adjusting information associated with a local place of a caller comprising a caller's local time, local date, international access code, local country code, and local area code if necessary.
  • Means for entering a telephone number sequence is associated with a called place which may include telephone code information comprising an international access code, called country code, and a possible called area code.
  • Means for pre-storing time-zone offsets of country and area codes is associated with places which may be called throughout the world. The offsets are defined with respect to a reference time zone.
  • One advantage of the present invention is that if a caller is requested to make a telephone call at a specified time at a remote location, the caller need only enter the remote time and telephone number of the remote location, and the international time indicating system will automatically calculate and display the caller's local time at which the telephone call should be made.
  • FIGS. 2A and 2B is an enlarged partial view of FIG. 1 respectively showing an inactivated display for the local time ofthe caller and an inactivated display for the remote time ofthe called place.
  • FIG. 5 is a simplified map showing the problem of problematic area codes that may include more than one local time.
  • FIGS. 6A and 6B illustrate two possible ways of initializing the local display by a caller whose telephone area code covers two time zones.
  • FIGS. 7A and 7B respectively show the remote time displays of distinct destination calls within a problematic area that are in different time zones from one another .
  • FIG. 12 is a flowchart of a reprogramming subroutine of the present invention.
  • FIG. 13 is a flowchart of a time-register-update subroutine ofthe present invention.
  • FIG. 14 is a flowchart of a time-set subroutine ofthe present invention.
  • the local time display 12 is positioned near handset 16 and is designed to display a caller's local time preferably with an AM/PM indicator, and the caller's local date.
  • the local time display 12 may also include the international access code "00" when calling out of India, followed by the country code and area code ofthe caller's destination, with or without an asterisk, whose function will be explained later.
  • the remote time display 14 is designed to display the called country's local specific time with or without an asterisk and the called country's date.
  • FIGS. 2A and 2B respectively show an enlarged view ofthe local and remote time displays 12 and 14.
  • an upper line 18 in the local time display 12 displays the caller's local time in seven segment display, such as a light emitting diode display or a Uquid crystal display, in the sequence: hours / minutes
  • the caller will first enter the local time with AM/PM to be displayed in the upper line 18. The caller will then enter the local date in the middle line 22. In the lower line 24, the caller will enter the international access code followed by the local country code. If the caller is in a large country with more than one time zone, the caller will have to enter an area code after entering the country code. The caller may be in a problematic area having two time zones within a single area or country code. In this case, the caller can arbitrarily select a convention to determine whether he is in the western or eastern side ofthe time dividing line.
  • the caller can enter an asterisk at the right of the lower line 24 as shown in FIG. 6B to show he is in the western side ofthe time dividing line.
  • the caller could have selected the eastern side of the time dividing line as the predetermined condition for entering an asterisk.
  • the information to be entered in the local time display 12 will have to be done only once, at the time when the telephone unit 10 is installed.
  • the local time display 12 will continuously display the local time, local date and local code with or without an asterisk for forming reference information for the computing system. Standard press buttons 42, as shown in FIG.
  • the local display shown in FIG. 2A and the remote display shown in FIG. 2B may be respectively provided in separate windows wherein each display can be simultaneously activated. However, the displays shown in FIGS. 2A and 2B may be provided within a single window wherein the local and remote displays shown in FIGS. 2A and 2B are non-simultaneously activated in alternating sequence with respect to one another. Also, the remote display may be modified so as to be substantially similar to the local display shown in FIG. 2A. Thus modified, the caller will be able to simultaneously see both the telephone number in the local display corresponding to the caller's location and the dialed telephone number in the remote display corresponding to the called place.
  • the impulse received by the computing system interacts with the reference information shown in the local time display 12 in the following manner.
  • the computing system with standard electronics understands that "44” represents the U.K. and further understands that "44” represents the only time zone in the U.K. such that there is no need for further entering an area code for its computing.
  • the number "44” is further computed with the number "91" present in the lower line 24 ofthe initialized local time display 12, as shown in FIG. 3A, in order to define the time difference between the local and called time zones - which is five hours and thirty minutes in the present example.
  • the international time indicating system understands whether to add or subtract the defined time difference.
  • a time keeping unit 114 uses a timer counter circuit and a crystal stabilized clock to continuously maintain the current time and other information as required by the local display 12 after the prior initiaUzation ofthe local display 12 through an independent initiaUzation routine.
  • a time adjust unit 116 reading the remote location code obtained while diaUng a distant call, is used to process the data under a program control by the corresponding software resident in the program memory, conventionaUy known as read only memory / erasable programmable read only memory (ROM / EPROM) 118.
  • the CPU Upon power-up, the CPU starts these T/C channels in appropriate modes - strobe / square wave generator in BCD counter mode - with suitable count divide ratios in auto reload fashion.
  • the time of day clock thus initialized, either interrupts the CPU after every second or its sub multiple to enable the time register update service or to provide corresponding status to be read and cleared by the CPU.
  • Approximately 16 bytes may be reserved per set to maintain the data from seconds to year of day and location code with special status in a packed or unpacked BCD mode.
  • Each of the local time, remote time and set points during the year or day requires such 16 byte records in time register form.
  • a single time of day clock and time offset data computed by the CPU is enough to maintain the time of day at different locations.
  • the location code and time set operations wiU now be discussed in detail.
  • the micro controller program requires the location code to fetch data from the look ⁇ up table stored in the ROM/EPROM memory.
  • the look-up table provides aU necessary data specific to every location code.
  • a typical entry requires several data bytes to hold aU of the information. It may be arranged in the form of an a ⁇ ay of records, where each record is pointed by the location code to which it belongs.
  • the time offset is used to adjust the remote time register. Status bits like "set point present", “display zone mark” and "read miscellaneous data" are selectively used for each location code. Additional data is preset as parameters to be used by the micro controUer whenever corresponding status bits are found active. Some of the status bits are described below.
  • the international time indicating system ofthe present invention may include an auto find operation for determining a caUer's local time for making a telephone caU based on a known remote time in which the caUed person wishes to receive the telephone caU.
  • Step 400 is the initial condition of vaUdly entering, on the international time indicating system ofthe present invention, digits including an international access code or NSD access code, a country code and an area code if required.
  • the system then waits until either of two predetermined function keys (such as F4 or F5) are entered (step 402). Entering, in this instance, function key F4 initiates an hours scroll in the remote display (step 404) by generating a scroll request command signal (SCRL-REQ).

Abstract

L'invention concerne un système d'indication du temps international, associé à un téléphone, un calculateur, un ordinateur, un progiciel, un circuit intégré, une horloge en temps réel ou similaire, pour afficher automatiquement l'heure et la date spécifiques d'un pays appelé après entrée du préfixe international, de l'indicatif du pays appelé et, si nécessaire de l'indicatif de la zone appelée. L'heure et la date dans le pays appelé sont calculées au moyen de décalages horaires stockés dans la mémoire du système, par détermination de la différence d'heure entre le fuseau horaire du pays de la personne qui appelle et le fuseau horaire du pays appelé. Les décalages sont définis par rapport à un fuseau horaire de référence. La différence d'heure sert à déterminer l'heure dans le pays appelé. Le système permet de calculer et d'afficher simultanément l'heure locale de la personne qui appelle, et l'heure du jour dans le pays éloigné à appeler.
