Hello, I am new to Kibana, I have a Table with 2 columns (dateini and date end) with format "dd / mm / yyyy hh: mm: ss". I need to change this format to "hh: mm: ss" and then do a subtraction of these 2 fields and display them in a metric.
For example: 19:01:00 - 19:00:00 = 1 minute difference
I would appreciate if you can help me.
