Description
Name: nt126004			Date: 01/14/2003


FULL PRODUCT VERSION :
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

FULL OPERATING SYSTEM VERSION :

Microsoft Windows XP [Version 5.1.2600]

ADDITIONAL OPERATING SYSTEMS :

Windows 2000, perhaps other Win32 as well.


A DESCRIPTION OF THE PROBLEM :
If the Windows timezone is set to "Santiago", with a GMT
offset of -4, the JRE uses a default timezone of
"America/Caracas", when it should be using
"America/Santiago". Both time zones have a -4 offset, but
they have different daylight savings rules.

As a result, Java apps appear to be an hour behind during
summer in Chile.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Set Windows timezone to Santiago, GMT -4.
2. Run the attached code.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Actual results:

default timezone = America/Caracas
correct timezone = America/Santiago
Time with default timezone = 16/12/02 00:00
Time with correct timezone = 16/12/02 01:00

Expected results:

default timezone = America/Santiago
correct timezone = America/Santiago
Time with default timezone = 16/12/02 00:00
Time with correct timezone = 16/12/02 00:00


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------

import java.util.TimeZone;
import java.util.Calendar;
import java.util.Date;
import java.text.DateFormat;

public class TZTest
{

	public static void main(String[] argv)
	{

		TimeZone defaultTZ = TimeZone.getDefault();
		System.out.println("default timezone = " + defaultTZ.getID());
		TimeZone correctTZ = TimeZone.getTimeZone("America/Santiago");
		System.out.println("correct timezone = " + correctTZ.getID());
		Calendar calendar = Calendar.getInstance();
		calendar.set(2002, 11, 16, 0, 0);
		Date date = calendar.getTime();
		DateFormat df = DateFormat.getInstance();
		System.out.println("Time with default timezone = " + df.format(date));
		df.setTimeZone(correctTZ);
		System.out.println("Time with correct timezone = " + df.format(date));
	}
}
---------- END SOURCE ----------

CUSTOMER WORKAROUND :
Manually set the timezone to the correct value.

SUGGESTED FIX Make the following change to test/java/util/TimeZone/tools/win32/win-java.txt and generate tzmappings. *** /tmp/geta17267 Tue Jan 14 20:02:01 2003 --- win-java.txt Tue Jan 14 19:47:26 2003 *************** *** 86,92 **** # # New in Windows 2000 Beta 3 # !

EVALUATION The tzmappings file for Windows has the wrong mapping for America/Santiago. See Work Around. ###@###.### 2003-01-15

WORK AROUND There are two workarounds. 1) Specify -Duser.timezone=America/Santiago for starting java. 2) Make the following change to <JRE_HOME>\lib\tzmappings (text file). *************** *** 64,71 **** Greenland Standard Time:-1,80:GL:America/Godthab: Newfoundland:-1,81::America/St_Johns: Newfoundland Standard Time:-1,81::America/St_Johns: !
