##### Relevant URLs
- https://docs.influxdata.com/flux/v0.x/stdlib/timezone/location/
- _Provide other relevant URLs (project issues, community threads, etc.)_

Start with the supplied Flux query and the linked timezone/location documentation, then reproduce the reported Europe/Istanbul result. Compare the documented behavior with the observed output and clarify the expected timezone handling; done means the issue has a confirmed cause and a specific documentation or product change identified.
