That's because the timestamp isn't generated by syslogd, but by the
program that logs the message.  This is what the -T option exists for --
except it only applies to system log messages received across the network.

About the only way I can suggest for solving this is to use rsyslog from
ports -- I believe that has the capability of changing the timestamp to
when it received the log messages, rather than when it was originally
generated.  Plus it uses a rather more sensible timestamp format so the
date-time is a single column in the output, and you can tell what the
timezone offset from UTC was.
