Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :

EXTRA RELEVANT SYSTEM CONFIGURATION :
default locale: de_AT
time zone: central european time (Berlin, Vienna), daylight saving.

A DESCRIPTION OF THE PROBLEM :
%tz of java.util.Formatter shows a wrong GMT timezone offset.
See example code.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the attached source code.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the GMT timezone offset of "%tz" should be the GMT time zone offset -
like "Z" of SimpleDateFormat.

SimpleDateFormat: 2005-06-08 12:56:22.177 +0200
format date+time: should be identical

ACTUAL -
SimpleDateFormat: 2005-06-08 12:56:22.177 +0200
format date+time: 2005-06-08 12:56:22.177 +0100
... %tz gives a wrong GMT time offset.


REPRODUCIBILITY :
This bug can be reproduced always.
