title: How to format syslog date to logstash date timestamp format
body: <p>I'm trying to convert the syslog date format to a date timestamp that kibana recognizes, since it always appears as a string once the log is processed to elastic search. </p>
  
  <p>This is what I've tried so far </p>
  
  <pre><code>input {
      file {
          path =&gt; "C:/Elasitcity/File Destination/logs2/*.*"
          start_position =&gt; "beginning"
          sincedb_path =&gt; "NUL"
           }
        }
  
  
  filter {
          grok { 
              match =&gt; {"message" =&gt;"%{SYSLOGTIMESTAMP:logstamp}.*POST for %{URIPATH:ServiceURI}"}
               }
  
           date {
      match =&gt; [ "logstamp", "MMM dd HH:mm:ss" ]
  
                         }    
               }
  output  {
      elasticsearch {
                      hosts =&gt; "localhost"
                      index =&gt; "nextgen2" 
                      document_type =&gt; "netboading"
                }
              stdout {}
          }
  </code></pre>
  
  <p>I'm trying to extract the date from this log below </p>
  
  <pre><code>Jun 12 04:27:35 1560306455 INCOMING: information 22.244.42.41 Jun 12 04:27:22 DPPRD01 [host_services][0x80e0013a][mpgw][info] source-https(IMS_SSL_29982): trans(2797190703)[12.6.1.16]: Received HTTP/1.1 POST for /services/NHgetInternetLimitsV1 from 10.6.17.166
  </code></pre>
  
  <p>I'm simply trying to get elastic search to acknowledge logstamp as a timestamp that kibana can use for dashboarding purposes.</p>
