There's no possibility to add more information that is not part of FIBS.
Oh well. But does that mean the gender, country and client info are part of FIBS?
No, they are not part of FIBS. What I meant was information that the FIBS server can't supply itself. The information you listed is user edited and is not available when the player is offline.
Why is the timezone interesting anyway?
Because there are a large number of tournaments happening that require players to arrange times to meet.
Just because players know the timezones doesn't mean they know when their opponent can play. Besides, you would only be able to see the timezone info when the person is online so it's really unimportant information. It's better to register information when you are able to play somewhere else, like in tourneybot. I.e. players can register when they can play and opponents can ask the bot when a certain player is available.
