      Description

      Completed an upgrade from Moodle 1.9.12+ to Moodle 2.0.2+ of all of our systems. Many of my assignments in the system with user data in them are returning these errors when visited. I have turned on the full debugging.

      Warning: mysqli::query(): (22003/1690): BIGINT UNSIGNED value is out of range in '(`mdl_viu_primary`.`s`.`timemarked` - `mdl_viu_primary`.`s`.`timemodified`)' in /share-viu/viu/moodlePrimary/lib/dml/mysqli_native_moodle_database.php on line 793
