  • Patent number: 7733743
    Abstract: A comprehensive time determining system includes a list of geographical locations located on a periphery thereof. The base section further includes a plurality of time zones associated with the geographical locations. The time zones are presented on a time strip on the base section. The list of geographical locations on the base section includes locations using standard time only. A first movable section includes a northern hemisphere portion and a southern hemisphere portion. The northern hemisphere portion and the southern hemisphere portion are each independently movable relative to the base section. The northern hemisphere portion includes a list of northern hemisphere geographical locations. The southern hemisphere portion includes a list of southern hemisphere geographical locations. The lists on the first movable sections contains locations using dual time, the northern hemisphere portion and the southern hemisphere portion being movable to select a desired position depending on the season.
