Windows 10: Wrong sunrise sunset time when using VPN

Hi,


Night light feature is really useful with automatic scheduling but when I use a VPN to connect to a different countries, the schedule of night light became wrong. Is there any settings to choose a region to help the automatic sunrise and sunset time scheduling on Windows 10 Night Light feature to show the time more accurately?


Thanks

:)

 

Sunrise and sunset times

Is it possible to add sunrise and sunset times to my Windows Phone 8.1 Calendar app as reminders?

 

Windows 10 Night Light Schedule Has Wrong Sunrise-Sunset Times

I have the Night Light schedule set to Sunset to sunrise, which is currently followed by (23:00 — 12:11). The problem is that the Night Light feature isn't turning on and off at appropriate times.

The computed times are wrong for my location, as sunset today is at 20:09 (UTC-7h), and sunrise tomorrow is at 04:10. The end of astronomical twilight, at 23:25, is close to the first figure, but it starts at 00:55, which is very different from the second
figure. That figure isn't even close to civil twilight, which starts here at 03:29 tomorrow.

I will add that I keep my computer clock on UTC. It is almost as if the first figure uses local time, and the second figure uses UTC, which would be at least close to what I'd expect the times to be.

Windows 10 (1803) Night Light Sunset/Sunrise time incorrect

Thanks @Mark, though the graphics driver is actually been through a complete uninstall and re-install during this issue. Besides, it's weird if MS would rely on the graphics card for time purposes. Note, when using manual time, the color change is fine,
it's just sunset/sunrise times are wrong.
