Definitions

• the watch can be operated in a mechanical, electrical, electronic or other manner.
• the improved daylight saving time regulation should optimally take into account the energy-economic aspects without being associated with some kind of employment difficulties for parts of the population.
• the invention is therefore based on the object of providing a watch which, from a technical point of view, offers all the prerequisites for the problem-free introduction of improved chimerism control.
• the aim of the invention is to create a clock that makes it possible to display a fictitious time in addition to normal time - in Germany, this is Central European Time (CET). which deviates from normal time throughout the year according to a specific desired rule, according to the individual wishes of the user of the watch. It should be possible to implement a wide range of desired rules for the deviation and still be able to set and operate the clock in a simple manner.
• CCT Central European Time
• an additional device on a commercially available watch is such that an optional time at normal time (t) can be displayed in such a way that its deviation from normal time (t) is determined by a calendar date A.
• Day (day A) of each calendar year begins, up to a day (day B) of each calendar year determined by a calendar date B of a selectable and function that can be set on the clock (f 1 (t)) of the normal time that has passed since day A.
• the leap year correction could, for example, be such that the clock on February 29 of the leap year repeats the display of the optional time from February 28 unchanged and on the remaining days of the leap year as well as in a non-leap year. In this way, the same time display could be achieved for the same calendar days of each year, including leap years.
• FIG. 2 A preferred exemplary embodiment of the invention is illustrated below with reference to FIG. 2.
• the clock according to the example is a commercially available electronic clock, but is equipped with an additional device for setting a time (t ') that can be displayed differently from the normal time (t) - in Germany, this is the Central European time.
• the additional device is such that it has a first function
• ⁇ has the value "wired" in the additional device 1/2 year, the year taken in normal time (t).
• the clock according to the example can be set in a first setting state so that day A was entered as January 1.
• January 1 is one of those calendar days of the year when the sunrise is extra late.
• the day ß is fixed in the clock in such a way that it falls on the calendar date following the day A at intervals of 1/2 year.
• the clock can still be set in its first setting state so that the constant X was entered with zero hours.
• the clock thus set in a first setting state, realizes with its additional device the first and the second function in such a way that
• the optionally displayable time (t ') is identical to the normal time (t) for the entire year, which corresponds to the diagonal solid line in FIG. 2.
• the described first setting state of the clock is not suitable for using the clock for the purpose of an improved regulation of the summer time. It only serves to explain the mode of operation of the watch according to the invention.
• the day A is again entered as January 1st, but the constant X is entered as 3 hours.
• the additional device then implements the first and the second time deviation function in such a way that
• variable t is a dimension value inserted into the equations but dimensionally linked to the time unit "year", so that the function values representing the time deviations result in the time unit "hour”.
• f 1 (t) is the deviation of the optionally displayable time (t ') from the normal time (t) within the time period beginning on January 1st and ending with Tdg B, ie 1/2 year later, the following applies, for example, to the point in time exactly 1/4 year later than day A (or later than, for example, 0:00 a.m. on day A) that the optionally displayable time (t *) at the same time deviates by the same value from the non-normal time (t), which results if one uses the value 1/4 in the function f 1 (t) for t, ie the deviation is
• the deviation of the optionally displayable time (t ') indicated by the clock can be from normal time (t).
• the optionally displayable time (t ') of the normal time (t) begins to advance linearly with day A (or 0 o'clock of this day).
• the maximum of the advance on day D ie at 0 o'clock on the day following 1 January 1/2 year later, is the value that was entered for constant X, in the case of the example 3 hours.
• the lead of the optionally displayable time (t ') with the Tdg B decreases in a linear manner from the value
• the watch then repeats the optionally displayable time (t ') in the manner described until it is possibly changed to a changed setting state.
• the dashed line illustrates the time course of the optionally displayable time (t ') for the explained second setting state of the clock.
• the ordinate values for the respective time deviation are shown greatly exaggerated.
• the described second setting state of the clock also corresponds to an alternative to the currently applicable regulation, as an alternative to possible improved summer time regulation.
• the illustrated examples clearly show that the clock according to the invention can be set very easily for the optionally displayable time (t ') despite a large number of possible variations and is therefore user-friendly.
