[Building Sakai] Chrome and samigo assessment time?

Tue Feb 28 14:16:59 PST 2012

We do have multiple servers. The issue in the ticket doesn't seem to match,
though, because the student started well before the due time, and the test
would be over before the due date. Also, the ticket says "The error is
equal to the difference in time between when you started the first time and
the second time." This difference, for the student, was 60 minutes, whereas
the error was about 30 minutes.
