Hi Guys,

I have a message with timestamp 2019-10-25T10:39:44.079331-04:00. I want to use grok filter and match that time, so later on can transfer to other format.  
What will be the best filter for match such timestamp.

Thanks,

You can use [Logstash Date](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html) filter to parse the timestamp. Check the [match](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html#plugins-filters-date-match) format options. By default target will be @timestamp, you can configure "target" to store the parsed timestamp into a different field.
