There are really good reasons why an app should not change timezones on the server and why to store all datetimes in UTC. This is especially true in all distributed systems. The app must be designed in a way that it can convert from/to UTC while exchanging data with the outside world or only where it really needs to calculate with local timezones. I don't understand, why you would want to test a different date behavior in development server. Even if it would be possible in dev server, you can be sure that the app will break once it is deployed.
