I live in the central time zone, so my phone's " home time zone" is such. I'm in north carolina though visiting UNC and my clock still shows central time instead of eastern time. I tried changing it under clock but that didn't do anything.

BlackBerries don't update the time zone automatically when you move into a different one. You have to change it for yourself. I have a full explanation in the Time Zone Issues thread in my sig.
