Revision 4615

backport (glarose): Gateway update: report tests graded in the grace
period after the due time as having been completed at exactly the
maximum allowed time. Thus, if a test allows 20 min and there is a grace
period (defined in global.conf) of 2 min, a test submitted after 21 min
will be reported here as having been completed in 20 min, not 21.  This
avoids some confusion for instructors who aren't aware of the grace
period.

This update doesn't have any effect on the presentation of non-
versioned sets.
