Hi I think you could use something like **_[this](https://discuss.elastic.co/t/time-in-ist-for-log-rotation-logstash/211612/2)_**. The OP in that case was trying to use the local time, as converted from timestamp, to name files. The solution should be the same: you also want to convert the timestamp into your local time, if I unerstood your post corretly. Just substitute `filename` for your `newts`, play with the time format, and you should be good to go. This will not change `@timestamp` itself (and apparently there are reasons why you shouldn't), but you will get a variable with the local time that you can use. Hope this helps --- _[View the full topic](https://discuss.elastic.co/t/unable-to-convert-date-from-string-change-timestamp-value/216394)._
