ITimeDuration Interface

Provides access to members that control the Time Duration.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

The ITimeDuration interface is used to deal with time values which are simply a length of time, but not associated with a specific point in time.  For example, 3 hours is a TimeDuration since it does not tell you if it represents 1:00-4:00 or 5:00-8:00.  If you need to associate the TimeDuration with a specific point on the time line, you should use a TimeExtent.

Members

Description
Method AddDays Adds the input amount of days to the time duration.
Method AddDuration Adds a time duration.
Method AddHours Adds the input amount of hours to the time duration.
Method AddMilliseconds Adds the input amount of milliseconds to the time duration.
