<p>A novel twenty-four hour clock providing a continuous display representative of the rotation of the Earth relative to the heavens, and the changing position of illustrated geographic areas of the Earth relative to the fixed position of the Sun, thereby providing the viewer with a visual display of the local time of day and also the time of day in each of said geographic areas. The present clock also includes a fixed midnight mark representative of a location in the heavens, 180 DEG around the Earth from the fixed location of the Sun, coinciding with the occurrence of midnight at each geographic area of the Earth as said geographic area passes thereby, the geographic area in which the Fiji Islands and New Zealand are located being designated the International Date Line. The present clock is characterized by the presence of a progressing day-indicating means which provides a clear visual representation of the geographic portions of the Earth experiencing the new day and the old day as concurrently experienced in different geographic areas of the Earth, thereby providing the viewer with a clear visual indication and, if desired, digital identification of the local time and calendar day and the time and calendar day in all geographic areas of the Earth.</p> |
