9.2.17: Timing adjustable

Where ICT is a web page, it shall satisfy WCAG 2.0 Success Criterion 2.2.1 Timing Adjustable.

WCAG 2.0 success criterion: Timing Adjustable

For each time limit that is set by the content, at least one of the following is true:

  • 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.

NOTE: This success criterion helps ensure that users can complete tasks without unexpected changes in content or context that are a result of a time limit. This success criterion should be considered in conjunction with WCAG 2.0 Success Criterion 3.2.1, which puts limits on changes of content or context as a result of user action.
