[syslog-ng] Invalid parsing of syslog messages having timezone

Hi, Following is the syslog message received from Cisco router : *Mar 1 09:30:25.249 UTC: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel2, changed state to down As, you can see UTC is included in the above timestamp. That is why value of $PROGRAM is UTC and $MSGONLY is %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel2, changed state to down. What should I include in the syslog-ng.conf so that time zone is ignored?
