Time Zone Problem

My time zone is wrong and I want to change it. Could you please help me?

Hi tremo, click on your User CP and "Edit Options" on the left side there. Nearly at the bottom of the page there's an option called "Time Zone" All timestamps displayed on the forums can be automatically corrected to show the correct time.... -- you have to select the right zone there and click on "Save changes" then.

thank you very much for your help
