Problem

How do you update the time zone data within API Gateway's Java? For example, Brazil recently changed their schedule for DST and it's not clear which versions have a copy of Java with the right time zone data.

Resolution

You should follow KB 179115 to find your Java version, then consult Oracle's time zone documentation to see if you have the time zone data which contains the changes relevant to you. If not, you should update your gateway to a version that does contain the change, or use Oracle's tzupdater tool to update the time zones in your copy of Java. The SP release notes on Sphere will mention any updates to Java in that SP.

Newer releases based on OpenJDK can instead use Azul's ZIUpdater tool to update their copies of Java.
