When someone leaves a message the time stamp is off. The displayed time on the front of my phone is correct. My service address is correct. I've tried calling in and visiting a store and there doesn't seem to be anyone to help. I moved to AZ from CO and my number is still a CO number, but it really doesn't pass the common sense test that my time settings wouldn't adjust to whatever time zone I'm currently in. I recently visited Missouri and the issue still existed. Someone would leave me a voice mail and it would have a Colorado time stamp on it. This is ridiculous and I can't believe that there's not some kind of work-around for this issue. Please help.
