TimeInterval

```
public interface TimeInterval
```
Represents a time interval defined by two TimePoint objects. Both time points objects have the same time base for counting relative time. This means that getDurationSeconds() is always equal to (getEndPoint().getRelativeSeconds() - getStartPoint().getRelativeSeconds()) if the second timepoint isn't null. The time base for time points is specific to a particular service that returns such an interval.
The start timepoint may be infinite (see TimePoint.NEVER). In this case the end timepoint is always null.
