ABSTRACT:
A system for sharing presence-based time-zone information includes a database, and a controller. The database includes a plurality of presence profiles, each presence profile maintaining, for an associated network user, one or more network device identifiers and, for each network device identifier, a current presence status, indicating network availability, and current time-zone information based on geographic location. The controller is able to receive presence information, determine a matching one of the presence profiles, update the current presence status and the current time-zone information in the matching one of the presence profiles, generate shifted time-zone information, generate a presence update, identify a subscriber address for receiving the presence update, and transmit the presence update to the subscriber address.
