Umbraco Cloud project timezone

Where can I verify, and possibly change, the timezone Umbraco runs with, in an Umbraco Cloud project?

I found some timezone-related things in Kudu → environment, but that seemed to be cloudflare related rather, due to prefix “cf” on everything.

I am doing some date operations and am suffering from hour differences on what I expect to see (timezone probably not Stockholm which is expected/works locally.

It seems you can set “secrets” for Umbraco Cloud, but not environment variables? Possibly the environment variable TZ could solve my problem but I find no where to set it?
