Hi I am trying to convert a date field that I have into milliseconds. I found this old post  
[https://discuss.elastic.co/t/logstash-convert-date-string-to-timestamp-in-millisecond/52845](https://discuss.elastic.co/t/logstash-convert-date-string-to-timestamp-in-millisecond/52845)

I am facing the same issue I have a date field exactly as his and I need to convert it to milli seconds his solution to do this was using the Ruby filter and doing this:

ruby {  
code =\> "event['milli'] = 1000\*Time.parse(event['[myDate]']).to\_f"  
}

however when I try to do it on my logstash 6.0.1 i get a Ruby error saying:  
`Direct event field references (i.e. event['field']) have been disabled in favor of using event get and set methods (e.g. event.get('field'))`. But im not sure how to change that Ruby code to work with the new logstash now. Any help would be greatly appreciated thank you!
