We're finally done talking about keyboards! Hold onto your hats, because we're about to get into WCAG 2.2., which is perhaps even more of an edge-of-your seat thriller than the last few sections. 2.2 stresses the importance of allowing users the time they need to enjoy the content on your site.
If some of the content on your page is time-dependent, such as a news site that automatically refreshes after a given period of time or an animation containing disappearing text, it may be hard for people experiencing some visual, physical, or cognitive limitations to accomplish the required action before the time limit expires. For this reason, WCAG recommends you don't include any time-dependent functionality on your webpage at all.
However, if it's crucial, then this guideline asks that you implement one of the following options:

In this scenario, the editors of New York Magazine would need to include some kind of mechanism that would allow users to shut off or adjust the automatic refresh settings.
As another example, let's check out that animated This American Life clip we included in our post on WCAG 1.4.7.
The words of David Sedaris's story flash across the screen much too quickly. Fortunately, since the video player provides users with the ability to pause and rewind the clip (not to mention, there's audio accompaniment), it shouldn't be an issue for anyone to understand.
Please note that this rule only covers time limits that are a part of the content you create. You are not expected to implement these changes to stuff that's an inherent function of the user agent or of the Internet in general, which would be out of your control.
There are a number of other circumstances in which you don't need to worry about time-dependent functions. You can leave time limits as they are if one of the following is true:
