I recently flew to Wisconsin (Central Time Zone) from New Jersey (Eastern Time Zone). When I arrived I immediately noticed that all my appointments on my calendar displayed on my LG Quantum shifted themselves exactly one hour earlier.  I called ATT Customer Care and spoke to two different techs. Both put me on hold while they contacted LG. LG had two suggested solutions. I was informed that this phone automatically sets the time zone since it monitors your location. The user is unable to do this manually. The first “solution” was for me to log on to my Windows Live Account in Hotmail and change my time zone setting on Hotmail to Central Time. I followed these instructions and the calendar on my mobile phone did not correct itself. The second “solution” (which was no solution at all) was to reset my phone to factory settings thereby erasing all of my data.  I could then re-sync my phone to my hard drive (which I did not have access to at the time) as well as to Hotmail. I was told that there was no guarantee that the second solution would work. I decided that it was best to take no action. When I returned to New Jersey after a week my calendar corrected itself and all my appointments moved to the correct time.  Has anyone experienced this same problem?
