Dennis,
The issue will almost certainly be with your system clock as I just logged in as you and can verify that times are all displayed correctly, which confirms that the user settings, server and site settings are correctly configured on your account. Every issue we have ever had with regard to wrong times has either been someone changing the default server-side time zone on their user control panel (which is ruled out, you are fine there) or, much more often, issues with their system clock settings (incorrect time, time zone, DST settings, etc.). You can also have some issues if, for some reason, JavaScript support has been disabled in your web browser as this will foul the local time detection routine most likely resulting in you seeing the native server time, which is CST as it is based in Texas...however JavaScript support should always be enabled for this site as there are many areas that depend upon such for proper operation.
The actual displayed times are all set relative to the client-side clock so any misconfiguration there will distort the displayed times. You may also wish to try another PC or mobile device for a moment to see the result.
But please let us know your findings when you have identified the cause as I certainly would like to know if it turns out to be anything other than the above.
