Abstract

An interactive device with local area time synchronization is contemplated. The device includes a communications module linkable to a corresponding communications module of one or more other interactive devices. There is also memory for storing a set of clock values including a time component, a date component, a daylight savings component, and an event component. A computer processor connected to the communications module and the memory is also included, and is programmed to actively maintain an actively maintained real-time clock based upon the set of clock values stored in the memory. The set of clock values stored in the memory is transferrable by the communications module to a corresponding clock of one or more other interactive devices.
