The default time zone set in the Tomcat might be different from the actual time zone set in the server. In such cases, set the JAVA_OPTIONS with property to reflect the corresponding Time zone. For e.g, to set the time zone to reflect US Time, add the below property into the JAVA_OPTIONS of Tomcat (bin): -Duser.timezone=US/Mountain.
