  1. I try to set different timezone as UTC, still get this error.
  2. Try to set enviroment variable from window as TZ='Asia/Bangkok' / UTC still this error
  3. Check my DB Oracle timezone
    SELECT DBTIMEZONE FROM DUAL; return +00:00 (UTC), my timezone: +7:00UTC as Asia/Bangkok
  4. my command
bin/logstash -f D:\\kynk\\ElasticSearch\\logstash-8.10.2\\config\\oracle-elastic.conf --path.settings D:\\kynk\\ElasticSearch\\logstash-8.10.2\\config

i try to add with/without --path.settings still this error
Anyone can shred some light. I'm real stuck. Many thanks.
