The clock on my Nexus 7 will not adjust to the correct time. I live in the Eastern Time Zone, but the default time is always one hour earlier. When I click on Clock, then the globe icon at the bottom, all the EST cities have the incorrect time (New York, Atlanta, Miami, Washington DC, etc).....all one hour earlier than they should be. I've gone through all the settings, but maybe I am missing something and need to make a manual adjustment somewhere, so that the time is corrected. Thanks for any assistance to fix this!
