Timezone offset issue

Issue

• We are noticing our jdk calls to grab date objects are 2 hours offset,
• It is presenting wrong times to several operating programs.
• We added a setting to the standalone.conf file to set the timezone
  JAVA_OPTS="$JAVA_OPTS -Duser.timezone=America/Chicago"

That fixed the problem after a service restat, but it happened again a few hours later. Restarting the server resolved it.
