That badge with the clock means that iOS 11 has learned, using machine learnin
g, that you often open this app at this time of the day, and it is placing it
in the dock on the right side, where suggested apps go, to make it easier to l
aunch the app if you truly are about to run the app.
大意就是iOS 11透过machine learning学习，了解你在这时间经常使用这个App，所以它
就直接出现在dock的右边，方便你快速启动App
