EAP6 audit logs via syslog have no time zone identifier

Issue

We are performing integration with a remote syslog receiver and they have reported that data does not arrive with a time zone identifier, see sample below:

Mar 5 09:37:20 rewrr000000719 jboss-eap-appname[1839]: 2014-03-05 09:37:20 - {"

Please let us know how to ensure the time zone aware timestamp is forwarded.
