I want to use visualization in dashboard to show number of logs for one day (from midnight to midnight). Used aggregation "Date Range" by field "log.timestamp", from now-1d/d to now/d, but I'm not sure it's showing correctly and the problem is that my timezone on kafka is somehow different. When it is 0:00:01 (when new day starts), my logs have timestamp of day before at 22:00:01. Basically, what is date range from-to I should set to to get count from only current day, on my index it is logs from eg 2019-01-01 22:00:00 to eg 2019-01-02 22:00:00 ---

Hey, dates are stored as UTC, `now` is also using UTC date. Is it possible that the date you stored is not UTC but differs by two hours, and thus you are seeing that difference? --Alex ---
