Yep, first thing I tried....Same thing happened on my Note 5 with the lock screen. Lock screen still showed Daylight Savings Time, while the alarm/system time was switched to normal time. Time was/is set to automatically update. A reboot fixed the problem.
Not seeing anything like that in settings.Friend of mine had this happen on her Samsung phone. She had disabled (turn off) something she didnt like. it was something daemon. After i turned it back on in her settings the widget updated.
