On the locked screen the time is one hours off the unlocked screen. I can change the time on the unlocked screen however I cannot figure out; - why there are two times when they should be the same, -how to change the time on the locked screen.
Not sure what a widget is. The two items you mentioned only reset the time on the unlocked screen which I have completed.
Once you unlock the screen the time at the very top of the page, in the thin black line is one hour behind the time on the blue screen. The time on the blue screen can be changed by the methods you mentioned.
