[syslog-ng] Logging timezone info in each message for V 1.6.8

Hello, Wondering if there is a way to print timezone with each message in the Version 1.6.8 ? Currently my message looks something like below Jan 21 12:22:12 <rest of the message> Instead I would like to see something like below Jan 21 12:22:12 PDT 2008 <rest of the message> or something in that line where I can see the timezone info. I have come across some timezone handling documents from - http://www.syslog.org/syslog-ng/v2/#timezone_handling But only for the Version 2.x and not for version 1.6.X I'd appreciate if you can share any tips for printing timezone ( or perhaps ISO format timestamp ) in each message for V 1.6.8 Thanks, -Manju
