Request a DateTime from GPS Module

Question

I am currently developing an android app that requires GPS module.

I have code like this:

 LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
 LocationListener mlocListener = new MyLocationListener();
 mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener);

public class MyLocationListener implements LocationListener
    {
     public void onLocationChanged(Location location)
     {
      if (location != null) {
    double gpsLatitude = location.getLatitude();
    double gpsLongitude = location.getLongitude();
    float acc = (float) (location.getAccuracy());
    Date gpsDate = new Date(location.getTime());
                }
         }
   }

1). I have searched what getAccuracy() returns. I found that it returns accuracy in meters. Is this correct ?

2). I want to retrieve the gpsDate from another button onClick. This LocationListener triggers when the gps detects movement or how ? Imagine that the user moves with the device around, stops and presses a button. On this press I need to save the date from gps to a file. How do I get this date ?

Thank you all for your time.
