Abstract

Consider a computer calendar application which maintains a data base of calendar events. The events consist of an optional start time, an optional end time, and a description. Current art provides for the entry and display of events for one or more days of events. The current art manages this by keeping the data base of calendar events organized by day, month, and year.

User Time Zones in a Calendar System

      Consider a computer calendar application which maintains a data
base of calendar events.  The events consist of an optional start
time, an optional end time, and a description.  Current art provides
for the entry and display of events for one or more days of events.
The current art manages this by keeping the data base of calendar
events organized by day, month, and year.

      This organization introduces problems in the entry and display
of events when the user is in a different time zone from the calendar
system.  This is often the case when users are connected via
telecommunications to a large computer system.  In many cases, the
user is not aware that the computer is not "local". In these cases,
either the user must adjust for the different zones or must enter the
events in local time, ignoring the time zone of the calendar event
data base location.  In both cases, the user must both know the time
zone where his calendar system is located.

      In the proposed method, each user may declare his or her own
time zone to the calendar system.  In the recommended implementation,
this will be saved as a signed integer number of minutes from the
time zone of the calendar system.  When events are entered in local
time, the time zone difference will be added, or subtracted, from the
entered time before storing in the event data base.  Thus all events
in the data base are in the time zone of the data base.  Simila...
