In some cases when an editor logs in to XperienCentral, the following error message is seen in the log:

This problem occurs when the Linux time zone data package (tzdata) is updated but the Java version in the environment is not. In most cases the solution is to update Java to the latest version within the major Java version used (Java 9, 11 and so forth).
