One usability problem that we have for the backup/restore module of Moodle is that, our instructors often backup their courses taught on moodle in previous semesters and restore them to the current semester. However, the due dates for the activities (quizzes, assignments, etc.) would still remain as they were previously. If Moodle could automatically detects the system clock or something and prompt the user whether he/she want Moodle to change the year to current year/semester (sort of a smart approach), I think that would be great! A lot of our instructors have requested such feature. This is particularly useful when some courses have a LOT of activities that require manual date changes (for due dates..etc.) for all the activities (quiz, assignments..etc).
This occurs mostly with the year from Fall to Spring semesters. For example, a course backed up in Fall, when restored in Spring semester it will have Fall's year on it (and all the activities due dates would remain last year).
