Bug gcj with date manipulations?

[Maurice DIAMANTINI <diam at ensta dot fr>]

Bonjour à tous !

I'm a new gcj user  and I try a program which
does work with javac/java but rise an error
with gcj.

My first impression is very hopefull, and I hope
to use java(gcj) instead of c++.

My gcl version come from cvs about a month ago (not sure)
and I'm trying to do some test to compare C and GCJ 
and the feature suported by gcl relatively to javac (jdk)  

    > gcj --version
    2.97
   
   (should'nt be a more verbose option like --version2
   giving compil date and anything usefull for
   version identification?)


My plateform is linuxppc on powermac blue G3 ( 2.2.17rms1)
(and I hope MacOS-X as soon as possible with X11 and full 
gcc :-)

------------------------------------------------------------
I rise an error with date format in the following :
Hier is the code :

import java.util.*;
import java.text.SimpleDateFormat;

public class Test  {    

  public static void main(String[] args) {
          
    // on déclare des formateurs de date et de temps :
    SimpleDateFormat df = 
          new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss.SSSS");
    SimpleDateFormat tf =
            new SimpleDateFormat( "mm'mn' ss.SSS's'");
  
    Date startDate = new Date();
    System.out.println ("Début à : " + df.format(startDate) ); 
        
    Date endDate = new Date();
    System.out.println ("Fini à : " + endDate); 
    
    Date duree = new Date(endDate.getTime() - startDate.getTime());
    // System.out.println ("durée : " + duree/1000 + 
    //      "." + duree%1000 + "s"); 
    System.out.println ("durée : " + tf.format(duree)); 
        
    return;
  }  // main
}

Standard sdk compilation :

> javac Test.java && java Test
