Once again I'm extremely puzzled by Moodle's database.
This teacher graded an assignment on March 19, 2015. However, if I look in the database, I can find the following fields:
mdl_assign_submission.`timemodified` = March 3, 2015, which is correct because this is when the student uploaded the assignment
mdl_grade_grades.`timemodified = NULL, which I can absolutely not understand. I thought this is where the date would reside.
mdl_grade_items.`timemodified`= November 13, 2014. Makes no sens at all.
Somehow, Moodle fills the above field with the correct date. But wherever I look in the database, I can't find the date on which an item is graded.
Does anyone know how the above field is filled?
