Hello René,
I'll try to set up VM to test following steps (so here it is untested)
1) open
${OM_HOME}/webapps/openmeetings/WEB-INF/classes/META-INF/mysql_persistence.xml
2) find <property name="openjpa.ConnectionProperties"
3) add ", serverTimezone=Europe/Berlin" to the comma separated values
run command line or web installer
