Definition	A page that contains time limits for user interaction or viewing content must provide a way to turn off, adjust or extend the time limits.
Purpose	People with physical disabilities may need more time to respond to web sites with time limits for selecting an option. People with visual impairments and visual processing learning disabilities may need more time to read material if the rendering of the material is automatically removed or obscured after a time period. Providing adjustable time periods in line with the persons capabilities makes it possible for people to complete the tasks associated with the website.

Techniques	Turn off: The user is allowed to turn off the time limit before encountering it. 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. 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 time. 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. Essential Exception: The time limit is essential and extending it would invalidate the activity. 20 Hour Exception: The time limit is longer than 20 hours.
