A DESCRIPTION OF THE PROBLEM :
Calling setTime() after or before calling setTimeZone() on a calendar object changes the date obtained by getTime() if a set() is called on the calendar.

when setTimeZone() is called after setTime() the returned time after a set to zero seconds is moved by several hours. In the other way the time is correct.

If a get() is called before the set(), we have the expected result.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
compile and run the attach program.
It shows
in 1 the combination setTime() then setTimeZone() then set() which is in error
in 2 the combination setTimeZone() then setTime() then set()
in 3 the combination setTime() then setTimeZone() then get() then set()




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the expected result should be

1) after setTime then setTimeZone Date = Fri Jan 09 07:00:00 CET 2009
1) after set Date = Fri Jan 09 07:00:00 CET 2009
2) after setTimeZone then setTime Date = Fri Jan 09 07:00:00 CET 2009
2) after set Date = Fri Jan 09 07:00:00 CET 2009
3) after setTime then setTimeZone then get Date = Fri Jan 09 07:00:00 CET 2009
3) after set Date = Fri Jan 09 07:00:00 CET 2009

1 is 14H and should be 07
ACTUAL -
1) after setTime then setTimeZone Date = Fri Jan 09 07:00:00 CET 2009
1) after set Date = Fri Jan 09 14:00:00 CET 2009
2) after setTimeZone then setTime Date = Fri Jan 09 07:00:00 CET 2009
2) after set Date = Fri Jan 09 07:00:00 CET 2009
3) after setTime then setTimeZone then get Date = Fri Jan 09 07:00:00 CET 2009
3) after set Date = Fri Jan 09 07:00:00 CET 2009

all times are the same

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
package tst;

import java.util.TimeZone;

public class CalendarAdjust
{
public static void main(String[] args)
{

Calendar cal = Calendar.getInstance();

}

}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
allways call setTimeZone before setTime
