Happens sometimes when it loses connection from the network around the time it was udating the the current time.
One of the work arounds if your in an area with spotty connection is to manullay set your timezone and disable automatic updating from the server.
Okay just wondering if anyone has had any issues with the world clock. When I go in to the clock app it shows my current location is about 6 hour ahead of my home location. example right now the home location shows 9:56 am but my current location shows 3:56 pm. Is there a way to fix this issue. I turned off the sync and on again but nothing, I have cleared the data and nothing. Not sure what else to do here.
