System: Linux churchill 2.4.3-12 #1 Fri Jun 8 15:05:56 EDT 2001 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu

>Description:
TimeZone.getDSTSavings() was added in JDK1.4 and isn't implemented.
>How-To-Repeat:
; cat DSTTest.java
import java.util.Date;
import java.util.TimeZone;
public class DSTTest extends TimeZone {
private final boolean useDST;
public DSTTest(boolean useDST) {
this.useDST = useDST;
}
public int getOffset
(int era, int year, int month,
int day, int dayOfWeek, int milliseconds) { throw new Error(); }
public int getRawOffset() { throw new Error(); }
public void setRawOffset(int offsetMillis) { throw new Error(); }
public boolean useDaylightTime() { return useDST; }
public boolean inDaylightTime(Date date) { throw new Error(); }
public static void main(String[] args) {
System.err.println(new DSTTest(true).getDSTSavings());
System.err.println(new DSTTest(false).getDSTSavings());
}
}
; javac DSTTest.java && java DSTTest
3600000
0
; gcj DSTTest.java --main=DSTTest
DSTTest.java: In class `DSTTest':
DSTTest.java: In method `DSTTest.main(java.lang.String[])':
DSTTest.java:21: error: Can't find method `getDSTSavings()' in type `DSTTest'.
System.err.println(new DSTTest(true).getDSTSavings());
^
DSTTest.java:22: error: Can't find method `getDSTSavings()' in type `DSTTest'.
System.err.println(new DSTTest(false).getDSTSavings());
^
2 errors
But after the below patch:
; gcj DSTTest.java --main=DSTTest && ./a.out
3600000
0
>Fix:
*** TimeZone.java 13 May 2002 20:10:36 -0000 1.14
--- TimeZone.java 31 Aug 2002 03:29:28 -0000
