### Question:
DefaultTemporalCoordinateSystem extends DefaultTemporalReferenceSystem implements TemporalCoordinateSystem { @Override public Unit<Time> getInterval() { return interval; } DefaultTemporalCoordinateSystem(Map<String, ?> properties, Unit<Time> interval, Date origin);  DefaultTemporalCoordinateSystem(final TemporalCoordinateSystem object); static DefaultTemporalCoordinateSystem castOrCopy(final TemporalCoordinateSystem object); @Override @XmlElement(name = "originPosition", required = true) Date getOrigin(); @Override Unit<Time> getInterval(); @Override Date transformCoord(final TemporalCoordinate c_value); @Override TemporalCoordinate transformDateTime(final Date dateTime); @Override boolean equals(Object object, ComparisonMode mode); @Override String toString();  }### Answer:
@Test public void testGetInterval() { Unit<Time> result = temporalCoordinateSystem1.getInterval(); assertFalse(temporalCoordinateSystem2.getInterval().equals(result)); }
