WARNING! It is necessary to download the latest DST patch for your specific platform. If you do not, applications written in Java may report the incorrect local time. See link below:
In the 2007 USA DST change, daylight saving time moved ahead 3 weeks in March and behind 1 week in October. This has affected the local reported time for JRE applications. A problem persists despite the fact that a new JRE has been released with updated DST specifications. Because of this, it is necessary that users install a patch. Download the appropriate patch for your platform at the Sybase Web site.
Once you have downloaded the appropriate patch follow the instructions below:
Apply the tzupdate tool with -bc (backward compatibility) and -f (force) options.
java -jar tzupdater.jar -bc -f
