The [path option](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-file.html#plugins-outputs-file-path) of the file output plugin allows for variable interpolation (as can be seen in the example), so you can use that to rotate files on a specific interval.

I believe Filebeat creates a _@timestamp_ in each event with the time stamp when it read that specific line, so you can use that.
