Here is the gist of the problem :
1. You need Java 1.4.2.11 or Java 1.5.0.6 to get the new zone files.
2. If you are using NSTimestamp, you need to not use it for timezone
stuff. WO still uses NSTimezone when you pass in a Java TimeZone, and
uses its own zone files, which are hopelessly out of date.
In our case, we store everything in the db as GMT, and then convert
on the fly depending on what zone the user is in. We use the
following methods :
/**
* Returns a new time stamp for the passed in Timezone.
*
* @param iMillis time stamp to be converted
* @param iZone Timzone in which conversion is needed.
* @return an NSTimestamp with date converted to iZone.
*/
public static NSTimestamp changeDateForTimezone(long iMillis,
TimeZone iZone) {
long anOffset = 0l;
if (iZone != null)
anOffset = iZone.getOffset(iMillis);
return new NSTimestamp(iMillis + anOffset);
}
public static NSTimestamp changeDateForTimezone(NSTimestamp
iTimestamp, TimeZone iZone) {
return changeDateForTimezone(iTimestamp.getTime(), iZone);
}
Hope this helps.

I notice the sun tool says:
The java.vendor property value must be "Sun Microsystems Inc.".
so I bet it won't work for Apple JVMs. It didn't appear that Apple
had a JVM release that met the dates shown on the sun page. Maybe
we are stuck?
Thanks to all for the VERY timely replies to my problem. Art is
correct that compiled timezone files are kept in /System/Library/
Frameworks/
JavaVM.framework/Versions/1.5.0/Home/lib/zi.
Apparently the file for my area "Denver" has been fixed in a newer
version of the apple java. I downloaded that version and copied the
"Denver" file from the zi directory into my 1.5.0 zi directory. Now
the problem is gone (so far) on the development system, but still
does not work correctly on the deployment system :(
Still searching for a reason...
Thanks to all,
Dan Faber
