The sidebar won't include the Game ID as that isn't determined until a game ends, and it'll probably include your IGN eventually, but not right now.
As far as time goes - CST/CDT time is displayed on the sidebar because it's the timezone that most of our development team lives in, and therefore it's the time that maintenances are usually announced in; displaying it on the sidebar relieves the need for people to convert the time to/from their timezone. It also used to be the timezone all of our servers were in, allowing us to easily look up server logs if people submitted a screenshot of a bug (all of our servers now operate in UTC time, but it's still not hard for us to convert UTC to C(S/D)T - subtract 6 hours if winter, 5 hours if summer). We have something planned to automatically detect your timezone and correctly display your local time in the sidebar, but there's no ETA on that.
