Why the time shows "00:00:00"

Question

Hi, I'm creating timezone convert function to cover that the zone that New_time function won't cover in 8i with the help of JAVA.
However, with the code below, the time will be always "00:00:00" when return from Oracle.
Do I missing something? Here are the code:
create or replace and compile java source named "DateConvert" as
import java.text.*;
import java.util.*;
public class DateConvert {
     public static String getDate(java.sql.Date oraDate, String tz1, String tz2) {          
          long inTime = oraDate.getTime();
          Date javDate = new Date(inTime);
          DateFormat formatter = new SimpleDateFormat("MM-dd-yyy HH:mm:ss a");
          formatter.setTimeZone(TimeZone.getTimeZone(tz1));
          formatter.setTimeZone(TimeZone.getTimeZone(tz2));
          return "result: " + formatter.format(javDate) + " Oracle Date: " + oraDate + " Java Date: " + javDate;
create or replace function TZ_Convert(myDate Date, tz1 varchar2, tz2 varchar2)
return varchar2
as language java
name 'DateConvert.getDate(java.sql.Date, java.lang.String, java.lang.String) return java.lang.String';
variable test varchar2(600);
call TZ_Convert(sysdate, 'SGT','GMT') into :test;
print test;
Here are the result:
vw@abt> print test;
TEST
result: 04-10-02 05:00:00 AM Oracle Date: 2002-04-10 Java Date: Wed Apr 10 00:00:00 CDT 2002

Use a java.sql.Timestamp instead of java.sql.Date
