<pre>My patch proposal<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>If syslog is handling a message with an rfc 3164-type timestamp then a hostname that begins with 4 digits, <o:p></o:p></pre>
<pre>the time parser will mess up because it thinks that it is dealing with a linksys-style timestamp that includes the year,<o:p></o:p></pre>
<pre>when the rfc3164 timestamp does not. I wrote a patch that adds a strict rfc3164 parsing option to the syslog startup.<o:p></o:p></pre>
