I have an index which has 3 fields of "date" type, @timestamp, startTime and endTime with built-in format (default strict\_date\_optional\_time || epoch\_millis). Run a query, elastic search (7.6.1) return iso8601 String for @timestamp while epoch milliseconds for startTime and endTime. Is there a way to make elastic search to return the same format of the date type?
