Another attempt:

Checkpoint 2.4

For events whose expiry depends on user actions, do either of the following:

* Give users control over how long they can interact with the content.
* Give them as much time as possible.

For events that occur in real time independent of user actions, warn 
the user when the event expires.

	[Edited to remove the impossible-to-understand multi-clause
	run-on sentence, a major failing of all WCAG documents, which
	need to use simpler, less pretentious, more conversational

Success criteria

You will have met the requirements for cases involving user actions 
if any of the following is true:

* The user can deactivate automatic timeouts or updating altogether.
* The user can set the timeout to a figure up to 10 times the default 
timeout period.
* The user is warned before time expires and given at least 10 
seconds to extend the time available.
* The user is allowed to set how often the content is updated. 
[removed "in seconds"]
* The user is given as much time as possible.

In all cases, the user must be able to freeze moving text.
