> Hello, My Elasticsearch is version 7.5 I have a\> date type - @timestamp field b\> string type - event\_timestamp field (format: 2020-03-06 20:28:33:232123456 +0000) sent in each event. What I want to achieve: 1st, I want to copy @timestamp field to another field called ls\_timestamp (ls\_timestamp should have same format as @timestamp after copying) 2nd, I want to copy event\_timestamp field value to @timestamp (I want to see all the nanoseconds from event\_timestamp in @timestamp after copying…
Just posting that here, seems like logstash related. Can someone guide me here?

You can use mutate+rename to move fields around, but you [cannot](https://github.com/elastic/logstash/issues/10822) have nanosecond precision for a logstash @timestamp field.

@Badger
Just curious, I thought date\_nanos was introduced to achieve nanosecond precision in ES 7.0 onwards? Is it something work under progress then?
Then can I use event\_timestamp (2020-03-09 04:58:54.497305256 +0000) in my case, for nano second precision by simply converting into date\_nanos type? If so, what would my index template look like?

Yes, it was. Support for it may have been added in Kibana too for all I know. But it wasn't added in logstash.

Thanks @Badger.
I was doing this to be able to sort data based on @timestamp in nano precision level.
Just to share to everyone, As a workaround, I achieved this by changing event\_timestamp field to date\_nanos type and recreating index with event\_timestamp. Now I am able to sort data on nano precision level based on my producer timing (event\_timestamp).
