Your smartwatch tracks your steps and sleep. Now, the makers of the Apple Watch want to track your sunshine. Apple's Time in Daylight feature uses the watch's ambient light sensor, as well as its GPS and motion sensors, to detect whether a person is outside. Clouds, shade and even a long-sleeve shirt can affect results. The feature is available on Apple Watch Series 6 or later models.Subscribe to The Post Most newsletter for the most important and interesting stories from The Washington Post. Yo
