Oracle/Java Time Discrepancy

Question

I have an Oracle procedure that rebuilds the index and a java application that calls the procedure. I don’t pass any timestamp at all, I just tell it to start and how long (approx) to run and then post the results in the GUI. When I run the procedure in the Oracle SQL Developer the start time is correct, however, when I run the same procedure though my Java Swing app the time stamp is 4 hours ahead of the current time. This confuses the users and is driving me nuts! The DB and the application are on one machine so there shouldnt be a time discrepancy. Any advice on how get Oracle to have the right time?
For a test I ran the following code:
public void retrieveTimeZone()
String query = "select to_char(current_timestamp, 'dd Mon yyyy hh24:mi:ss') from dual";
CallableStatement cs = null;
ResultSet rs = null ;
logMonitorList = new ArrayList();//reset list
TimeZone tZone = TimeZone.getDefault();
System.out.println("Java Date=" +new Date().toString());
System.out.println("tZone=" +tZone.toString());
try
logger.logEvent(className, "retrieveTimeZone", "Query=" +query);
cs = getDBConnection().prepareCall(query);
rs = cs.executeQuery();
while(rs.next())
System.out.println("Oracle through Swing app time="+rs.getString(1));
catch (SQLException e)
logger.logEvent(className, "retrieveLogMonitor", e.toString());
finally
//close connections etc…
The output is:
Java Date=Thu Jun 12 17:18:57 EDT 2008
tZone=sun.util.calendar.ZoneInfo[id="America/New_York",offset=-18000000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=America/New_York,offset=-18000000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]]
Oracle through Swing app time=12 Jun 2008[b] 21:18:57

Hi,
I guess this is the same query with solution posted on: http://forum.java.sun.com/thread.jspa?threadID=5304867&tstart=60
