is there a way to get the current date in Kibana? We need to calculate the days between a date inside an index and the current date. We haven't been able to find a proper Lucene expression to get the current date. We have thought about adding a field in the source ES index to get this date or adding a scripted field to the query in order to get this date. Has any one of you got this current date before inside Kibana? Could there be a workaround using ES to get the date in Kibana?
