Adjust your time by simply selecting the right offset by the hours... don't necessarily go by the exact name.. could just be a glitch... but you can pick any precise hour offset, so just go to your control panel and adjust accordingly.
To deal with your issues of having forums disply as "read" .. try two things. First, use the "mark all forums read" option in the lower left, then close your browser after you clear all the cookies from "tools" --> "internet options" ---> "delete cookies" and then try to login again and see if that solves the issue.
Also make sure your browser is set by: "tools" --> "internet options" ---> "settings" ----> and that "check for newer versions" is set to "automatically"
Note, these are only for MS Explorer.
Hope that helps.
