Windows can be like f.lux now

While poking around my display settings after the Windows 10 1703 update, I saw a new Night light entry. Like f.lux, it allows you to set a different color temperature for dark hours. I appreciate that being an OS feature, since every application that runs on startup is another delay between booting and working. It will only detect your sunset time if location services are on, but when I turned them on, it did not seem to determine my daylight hours. For now, I have the hours manually set. Strangely, my two identical monitors now show the same color quite differently. I'll see how this goes for a few days; there's always f.lux again if Windows doesn't handle it as I'd like.
