I have the weather & clock widget on my home screen. For two days in a row now, the time will suddenly change to 7 hours ahead, and then it changes back on its own about 6 hours later. The "main" clock on my phone is correct, and if I update the weather, it lists as correct when last updated. But even though the main clock knows it's 2pm, the widget shows as 9pm. Any idea what can be done?
