This bug has been copied from bug #583621 and has been proposed to be backported to 5.5 z-stream (EUS).
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: The previous rsyslog release introduced a new format of the message timestamps. However, certain utilities such as logwatch may have been unable to parse this new format properly. To prevent this, the "$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat" directive has been added to the /etc/rsyslog.conf configuration file to ensure that the old format is used by default.
