ITimeDuration Interface

Provides access to members that control the Time Duration.

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

	Name	Description
	AddDays	Adds the input amount of days to the time duration.
	AddDuration	Adds a time duration.
	AddHours	Adds the input amount of hours to the time duration.
	AddMilliseconds	Adds the input amount of milliseconds to the time duration.
	AddMinutes	Adds the input amount of minutes to the time duration.
	AddNanoseconds	Adds the input amount of nanoseconds to the time duration.
	AddSeconds	Adds the input amount of seconds to the time duration.
	AddWeeks	Adds the input amount of weeks to the time duration.
	Compare	Compares this time duration to the other time duration. Returns -1 if this time duration's value is less, 1 if greater, and 0 otherwise.
	Days	The time duration days component.
	Hours	The time duration hours component.
	IsZero	Indicates whether the time duration's value is zero.
	Minutes	The time duration minutes component.
	Nanoseconds	The time duration nanoseconds component.
	Positive	Indicates whether the time duration value is positive or negative.
	QueryDayFraction	The time duration day fraction portion as a day fraction. Corresponds to the Hour, Minute, Second, and Nanoseconds properties.
	QueryDayFractionNanoseconds	The time duration day fraction portion as the number of nanoseconds elapsed since midnight. Corresponds to the Hour, Minute, Second, and Nanoseconds properties.
	QueryTicks	Obtains the time duration as the number of ticks.
	QueryTotalDays	Obtains the time duration as total days floating point value.
	QueryTotalHours	Obtains the time duration as total hours floating point value.
	QueryTotalMinutes	Obtains the time duration as total minutes floating point value.
	QueryTotalSeconds	Obtains the time duration as total seconds floating point value.
	QueryWKSTimeDuration	Obtains time as a WKSTimeDuration.
	QueryXMLTimeDurationString	Obtains the time duration as an XML time duration string.
	Reset	Reset the time duration to zero.
	Scale	Scales the time duration by a scale factor.
	Seconds	The time duration seconds component.
	SetDayFraction	The time duration day fraction portion as a day fraction. Corresponds to the Hour, Minute, Second, and Nanoseconds properties.
	SetDayFractionNanoseconds	The time duration day fraction portion as the number of nanoseconds elapsed since midnight. Corresponds to the Hour, Minute, Second, and Nanoseconds properties.
	SetFromTicks	Writes the time duration from a given number of ticks.
	SetFromWKSTimeDuration	Writes the time from a given WKSTimeDuration value.
	SetFromXMLTimeDurationString	Writes the time duration from an XML time duration string.
	SubtractDuration	Subtracts a time duration.
