Abstract
Abstract An electronic Personal Information Manager (PIM) including a calendar/scheduling system with an EarthTime(TM) module is described. In operation, the system tracks different types of times: "local" time, "home" time, and "remote" time. Home time is the time zone of where the user typically spends most of his or her time; this is usually the time zone for the user's home office. Local time is the time for the locality where the user is located physically at any particular instance in time. "Remote" time represents the time zones of the other individuals (i.e., other than the user). The system may show events and appointments in the user's own "local" time (or other user-selected type of time), regardless of where the user is presently located. Using these three types of time (i.e., "local" time, "home" time, and "remote" time), the system provides improved interface and methods for scheduling and managing activities, such a phone conference, across multiple time zones.
