Time zone setting can (and should) be a user-specific setting.

Since a server application most likely isn't running as a the same user as the "real" logged-in user, there's no reason anything bad would happen.

CAN and SHOULD. but it's NOT.

Try 'export TZ=my/timezone/name' sometime.

What on earth are you doing using time zones in a server application? Time zone is purely presentation, you should be storing and calculating everything in UTC and only converting to time zone for presentation to a user based on that user's time zone (either via a user defined setting for your application or based on the current time zone setting of a user's system). You should never, ever, ever use the server's time zone to determine presentation to a user (or for anything really).

No, the server application should have it's own timezone setting, like almost any serious server has, and/or use UTC time.

And a distro must not assume you're using it for server applications, when you install a personal installation on your laptop.

don't tell me. tell the linux developers who created the server application.
