Windows 10: Night light schedule seems not to work properly

Night light schedule is on, sunset to sunrise and although it's broad daylight outside, it's on when I started my system today. Any ideas?

:)

 

Night Light not turning on properly

The new night light feature isn't working properly when scheduled. When it is well passed sunset, night light will show that it is on from the button in the action center, when in reality night light is not on at all. I have it scheduled to sunset and
sunrise and my time and time zone are set correctly, and the sunset times are accurate, but for some reason night light will just not come on until i manually turn it off and then on again.

these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Night light schedule not working

The "set hours" (not location) option for night light scheduling is not working on my Surface Laptop 3. When the time hits for it to turn on, it doesn't and I have to do so manually and when morning hits for it to be turned off, I again have to do it manually.
How do I fix it so that the schedule works?
