[SOT]: Postfix/syslog date format

[Lima Union]

Hi, I believe that this question is slightly OT but I'm seeing this
syslog format in Postfix: "Apr 10 08:53:12 relay1
postfix/cleanup[16550]:.....", my question is if there's a way to have
also printed the year in the date field? while looking for historic
data it can be really useful. I'm running RHEL 5.6 with the default
syslog package, I've looked at the man page and googled without much
success, any ideas?
TIA!
