itk::RealTimeInterval Class Reference

#include <itkRealTimeInterval.h>

Detailed Description

A data structure for representing the time span between two RealTimeStamps, with similar high precision and a large dynamic range to what the RealTimeStamps offer.

This class represents the difference between two time points, typically for applications that need to mark the time of acquisition of data with high precision (microseconds) and a large dynamic range (years). This class will be the natural representation for the duration of a video sequence, or for the time that has passed between the acquisition of one images and a subsequent one.
