21. A method for presetting a clock having an electronic control circuit, interface means assigned to the electronic control circuit, a time display, an electronic control circuit, and a time base, and memory cooperating with the electronic control circuit, the memory storing data necessary for displaying correct information on the display, the method comprising the steps of:

  • prior to distribution of the clock, loading into the clock a basic data set comprising geographical region data and time of day data in the geographical region by way of a person operating a setting means that communicates with the electronic control circuit via the interface means, each said time of day data of said basic data set being associated with a specific geographic region in which the clock is destined for use; and

    updating the display by way of the time base during transport of the clock such that a correct time associated with the specific geographic region in which the clock is destined for use is displayed on the clock upon connecting the clock to a power grid;

    wherein upon connecting the clock to the power grid, the basic data set is used by the electronic control circuit to automatically calculate a time associated with the specific geographic region to display on the clock at least one of a current time, a current date and a current day of the week at the specific geographic region that the clock is in use.
