Ok, ruby filter is the winner. This worked.

```
	ruby {
		code => "event.set('@timestamp', event.get('last_execution_time'));"
	} 

"last_execution_time" => 2017-03-09T04:07:51.520Z
"@timestamp" => 2017-03-09T04:07:51.520Z

```

Is that ok to use or do you know of a more optimal way ?

Thanks,  
E
