Hi,

I need to have a time limit on a survey. There are 50 questions and the participant has only 45 minutes to answer as many questions as they can.

Is there a way to have a time limit on a survey or a question group so that after 45 minutes they will end up at the 'end message'.

Cheers

Great, is there a ‘time limit’ function?

Yes www.limesurvey.org/manual/Question_type_-_Short_free_text#Timer

Great, is there a ‘time limit’ function?

Only for questions, not for the whole survey.

In previous version : using time limit / movenext work on group by group mode : on question with movenext on time limit movenext for all group

Yes, but from what I understood, here it should be for the whole survey. So then you would have to use the all in one mode to achieve this, which is generally not very practical.

I was thinking to put all the questions in one group, questions displayed after each other and then have the group expire after 45 minutes.
Would that work and how would I write that ie.

{time_limit} ?? would I write it in the Relevance equation for the question group?

This won't work. The timer is only valid for ONE specific question. If this question is in the same group as other questions AND this group is shown as one (one page for all "group by group"), then it might work, but not if you put them all in one group, but show them in the mode "question by question" it won't work.

If you need a question by question mode with such system, i think you need make your own system.

1st idea :
in 1st group, 2 question hidden
- equation TimeStart : {if(is_empty(self.NAOK),strtotime(date("now")),self.NAOK)}
- short text hidden TimeCurrent
Between each question :
- equation question TimeSet1 (1 increment for each question) : {TimeCurrent=strtotime(date("now"))}

All question (TimeSet too) have this relevance equation : {(TimeCurrent-TimeStart) <= 45*60}

Nice!

But, wouldn't that just render questions irrelevant, instead of submitting the survey?

You would also want to add a text-display question with the opposite relevance stating that the survey time limit has been exceeded.

In question by question mode : irrelevant question are just removed, then click on move next => goes to end of page.

Another solution could be to put each question in a separate group.

I was wondering, can we display this timer somehow ?

I used "DenisChenu"s method and it works great
