      You need a quiz with some student attempts on an 1.9.x install using MySQL > 5.5.5. Make sure you can go to the quiz overview report without errors, and that the durations are displayed correctly.

      It would be good to also test an install using the minimum version of MySQL that Moodle 1.9 is meant to support.

      Description

      I am using mysql 5.5.9. I found that same issue was discussed
      at http://tracker.moodle.org/browse/MDL-26416, but for moodle 1.9.11+.
      The solution seems to be posted at https://github.com/moodle/moodle/blob/master/mod/quiz/report/overview/report.php#L210.

      I wonder the patch will be available for moodle 1.9.11+ soon.

      Thanks.
