But have you actually tested to see if the change was really needed. Doing a
diff and other various things aren't really telling you if something was
broken in the first place. I was given another java script, that works for
all places I believe.
------
import java.util.Date;
public class TimeCheck {
public static void main(String[] arg) {
System.out.println(new Date(1173599999999L).toString());
System.out.println(new Date(1173600000000L).toString());
System.out.println(new Date(1194159599999L).toString());
System.out.println(new Date(1194159600000L).toString());
}
}
------
So, for your case, you would complie this code and then run
/usr/java/j2sdk1.4.2_12/bin/java TimeCheck
and then
/usr/java/j2sdk1.4.2_12.sv/bin/java TimeCheck
And see if they are the same or different.
well:
$ cat /etc/sysconfig/clock
ZONE="America/Vancouver"
UTC=true
ARC=false
# rpm -e j2sdk
# rpm -ivh j2sdk-1.4.2_12-fcs.i586.rpm
$ export PATH=/usr/java/j2sdk1.4.2_12/bin:$PATH
$ javac DSTCheck.java
$ java DSTCheck
