Hi,

If you're looking something magical there isn't anything. Just declare expiracy timestamp and compare against it in code. It should be rather trivial to do with JS down counter to UI for mode concrete feedback to end user.

But keep final word of expiracy in Django code.

Hello,

I think you will  have to implement jquery/javascript to make the timer. After the countdown finishes js can post the form automatically.

Cheers.

Hello,

As I said, on client side doing timer requires javascript usage. But it doesn't remove need to actually make sure that no-one can manipulate duration of exam.

It's really trivial to have piece of javascript that would render plain javascript timer useless (like you could fill out form forever).

So to make sure cheating doesnt happen - at the moment exam is created exam end time should be recorderd on server side as well (in database for example). So even someone manages to hack the js (which is really simple) they can't overcome limitation from the server.

Like the rule #1 in web development says - "Never trust user input".

Here is an example of what everybody is telling you to do in javascript:

Look for runTime and retryTimer

That should have been runTimer and retryTimer
