Android - How do I change the time zone (which is disabled) in Honeycomb on a Samsung Galaxy Tab 10.1?

I downloaded a free app called TimeZone Changer to fix this problem. Still don't understand why Samsung disables this.

I could not get it to change timezone or time either. Could not make it stop using network time either. i did a factory reset (from settings | privacy), correctly set my timzeone this time BEFORE saying use network time, and that worked fine.

The problem is that the "Automatic Time Zone" setting on the Samsung Galaxy Tab defaults to on, and the preference to disable it is missing from the built-in settings application.

There is an app on the Android market specifically designed to correct this issue called Galaxy Time Zone Fix. It mimics the "Date & Time" section of the built-in settings application but adds the missing preferences.
