2.2.1 Timing Adjustable: For each time limit that is set by the content, at least one of the following is true: (Level A)
- Turn off: The user is allowed to turn off the time limit before encountering it; or
- Adjust: The user is allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or
- Extend: The user is warned before time expires and given at least 20 seconds to extend the time limit with a simple action (for example, “press the space bar”), and the user is allowed to extend the time limit at least ten times; or
- Real-time Exception: The time limit is a required part of a real-time event (for example, an auction), and no alternative to the time limit is possible; or
- Essential Exception: The time limit is essential and extending it would invalidate the activity; or
- 20 Hour Exception: The time limit is longer than 20 hours.
This success criterion requires that generally users & people with disabilities must be provided with enough time limit to complete the tasks. Imagine you are reading a web page or completing a task & if the web page expires without warning, you will get distracted & will not be able to finish the reading of the page or complete the task. Generally, users need more time to read such content & people with disabilities & elderly need more time than common users to read such pages.
There are some exceptions for this success criterion too pass
