Hello,
Many thanks to those who have tested.
My greatest thanks go to Art Kraymer who correctly pointed out that
this update was *not needed*. The j2sdk that we pushed out in the
errata's last time (j2sdk-1.4.2_12) actually has the correct time zone
changes.
but not for some Canadians; it contains date set 2006a; for
America/Vancouver we need 2006g. Thus for our systems I applied the patch
via tzupdater a few days ago to the Tier1 centre; here is example output
showing that the patch goes from set 2006a to 2007a:
# java -jar ~deatrich/tz/tzupdater2007a/tzupdater.jar -v -u
java.home: /usr/java/j2sdk1.4.2_12/jre
java.vendor: Sun Microsystems Inc.
java.version: 1.4.2_12
JRE time zone data version: tzdata2006a
Embedded time zone data version: tzdata2007a
Extracting files... done.
Renaming directories... done.
Validating the new time zone data... done.
Time zone data update is complete.
and diff-ing the orig. and the patched java tree:
# diff -r j2sdk1.4.2_12 j2sdk1.4.2_12.sv
...
Binary files j2sdk1.4.2_12/jre/lib/zi/America/Vancouver and
j2sdk1.4.2_12.sv/jre/lib/zi/America/Vancouver differ
...
In other words, it is often the small regional differences that matter..
cheers,
denice
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.
