Hi list

I ported the -T option from netbsd syslogd.c to freebsd syslog.

"Add a -T flag to syslogd, which causes it to use local time for
messages received from the network. Useful for collecting logs from
devices which do not have correct time or if you need localtime anyway.
It does not replace original timestamp. It just adds the localtime at
the beginning of the string"

Is this done correctly? I had no trouble during my tests with remote
logging from several router and switches from cisco and foundry.

If everything is correct, any chance we can add this to freebsd syslogd?

Regards,
Tom
