Hello. I'm using 1.6.2 and I've noticed that the chart that tells you the duration a student has been on a content page for does not work correctly.
I logged in as a student and loaded a content page. I stayed on it for about 20-30 secs. Then I logged in as the instructor to check the usage and it said 0:00:03.
Is this a known bug?
Thanks.

I'm unable to reproduce this. The tracker seem to be recording time as it should on our installations.

Greg,
Please see the attached screenshot to see what I'm talking about.
It seems to be accurately tracking number of visits, but the timing is not correct at all.
Thanks.

It may be related to the time expressed by PHP or MySQL. One may not be correct. The recording of tracker time has never been reported as a problem in the years the tracker has been available, so we can only assume it is an issue with the server, rather than ATutor.
Since we are unable to reproduce the problem, we can not treat this as a bug. If you want to investigate yourself, the code that generates the tracking data is in include/vitals.inc.php. Search the file for member_track.
You can compare the code in the file with that in the repository, to be sure it is the same.

Greg,
Strange, but I have confirmed that the tracker seems to be functioning properly in other courses. Can you think of any way that this could be a course specific problem?
Thank you.

Yes, strange. I have no idea why it would be a problem in one course but not another.
Perhaps you can monitor the problem on your system, and if you can recreate it, document any clues you might find.

Greg,
The only difference I can tell is that in the course that's having trouble, it's tracking time in "children" pages.
Could that be where the problem is?
Thanks.
