Last night we had to advance Eastern Standard Time by one hour. Despite the fact that the time is programmed to be automatic with GPS and cellular networks, I am still on standard time and it is impossible to set the correct time manually if we do not deactivate the automatic time. As soon I reactivate the automatic time, the standard time is coming back ! My cellular network is showing the advance time and I did receive and made phone calls during today. Do you think I need to have a software update to correct this situation ?
