Hi,  
I have captured a field Response time from the log file, but it is in milliseconds, is there a way to convert it in seconds in logstash using any plugin. I tried using mutate but it won't work. Kindly help me out.

Something like

```nohighlight
ruby {
  code => "event.set('fieldname', event.get('fieldname').to_f / 1000))"
}

```

should do it (assuming Logstash 2.4 or later).
