hi @Ramdev_Wudali

consider looking at scripted fields in Kibana ([https://www.elastic.co/guide/en/kibana/current/scripted-fields.html](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html)). Use a Painless-script to get the difference in time-stamps.

To get started, use this tutorial [https://www.elastic.co/blog/using-painless-kibana-scripted-fields](https://www.elastic.co/blog/using-painless-kibana-scripted-fields) on how to create scripted fields.
