#### Timing Adjustable

A

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.

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 Success Criterion 3.2.1, which puts limits on changes of content or context as a result of user action.
