I have set timezone in my metabase at (localization tab) as Asia/calcutta. But in my mongodb database still showing wrong time. How can I change timezone for my mongodb database. Also tried in datamodel but not find any option in that.
Post "Diagnostic Info" from Admin > Troubleshooting. Do that on every single topic you create, so I don't have to ask for this information every single time.
MongoDB is currently not supported: https://www.metabase.com/docs/latest/troubleshooting-guide/timezones.html
There's a lot of work being done currently to support timezones much better: https://www.metabase.com/roadmap/
