How to call it

For using the GPAbsoluteDate class, the developer has only to create such an object with these two possibilities:

gpDate = new GPAbsoluteDate("Date:");

… or, if we want to initialize the widget with a predefined date value:

final TimeScale TUC = TimeScalesFactory.getUTC();
final AbsoluteDate date0 = new AbsoluteDate(2010, 1, 1, 0, 0, 0., TUC);
gpDate = new GPAbsoluteDate("Date:", date0);

Here we have a complete example of a class allowing displaying such a widget using [GENIUS] functionalities (in the next examples, we will no more present such complete examples):

public class TestGPAbsoluteDate extends GPanel {

    private GPAbsoluteDate gpDate;
    
    public TestGPAbsoluteDate() {
        gpDate = new GPAbsoluteDate("Date:");
    }

    public void generic() throws GException { put(gpDate); }
    public void display() throws GException { generic();}

    public static void main(String[] args) throws OrekitException {

        PatriusDataset.addResourcesFromPatriusDataset();
        
        TestGPAbsoluteDate test = new TestGPAbsoluteDate();
        
        GFrame frame = new GFrame("Absolute date", test);
        frame.display();

    }

}

Note: it is mandatory to link with [PATRIUS_DATASET] data at least to take into account UTC/TAI gaps.

How to use it

To get a [PATRIUS] AbsoluteDate object, we will just have to call for the getPatriusObject() method as below:

final AbsoluteDate date = date.getPatriusObject();

How it is stored

Here is the XML format for such a date:

  <AbsoluteDate name="Date:">
    <String name="date">01/01/2010 12h34m56s123ms000us000ns</String>
    <String name="scale">UTC</String>
  </AbsoluteDate>
