Class TimeInterval

java.lang.Object

net.grelf.TimeInterval

All Implemented Interfaces:

java.io.Serializable

public class TimeInterval
extends java.lang.Object
implements java.io.Serializable

This class describes the start and end times of an image exposure. For a single image it is assumed that that the timestamp recorded by the camera is at the end of the exposure so the start can be found by subtracting the exposure time. A similar principle applies to a sequence of images that has been combined by GRIP into one image. Times are represented internally as ms since 1970.0 UT, in the usual Java way, so time zones are irrelevant.
