Many thanks John for that explanation as it really helped.  I think there are times when not being a developer or coder makes it rather hard to work out the exact meaning of some of these Success Criteria.  It makes me reticent about voting but I am reading and lurking!

Best wishes

Subject: Re: timeouts

Hi E.A.,

The Working Group's concern (as I recall) is that often the timeout period is not "exact" but rather an approximation, and they didn't want to get down to splitting hairs (especially since it would make testing a pain in the neck).

So, for example, if we say that an authenticated session will be terminated after 15 minutes, it doesn't force the page owner to police that timing to the exact millisecond: if it times out after 14 minutes and 47 seconds, well... close enough - the page will not be considered 'non-conformant' because the Timeout Warning wasn't specific enough. In reality, I suspect that the timing will be pretty accurate anyway, because it's a machine tracking it, and machines are good at that type of thing. But given network latency issues (etc.), it's really hard to be ultra-specific.

As such, it was felt that a modicum of flexibility would be prudent here, and we can ensure that this is clearly explained in the Understanding documents.

I am sorry I missed the change where it says  'estimated' length of inactivity - that would sow a seed of doubt in my mind - what is an estimated length of inactivity?

Subject: timeouts

Hi Folks

We may only be able to get the following wording on time outs in WCAG:
 Where data can be lost due to user inactivity, users are warned before an activity timer is set about the estimated length of inactivity that generates the data loss, unless the data is preserved for a minimum of 20 hours of user inactivity.

With the wording above, some people might warn the user on every page that a timer starts, and not at the beginning of the process. SO i wont be able to know, at the start of a process, that this process times out to fast for me to complete the task and just gives me more to read.

Do we still see value in pushing for this SC if we can only get in the wording above?

(note the original wording is here: https://www.w3.org/TR/WCAG21/#timeouts

comment summary is here: https://www.w3.org/2002/09/wbs/35422/Resolving_Timeouts/?)


All the best
