No problems Martin 
OK I understand it better now.
I use moodle as an online complement to face-to-face classes, and one of the great benefits is that it improves communication between my students for various things, including such things as attendance and homework. For example, if the students can check their own attendance online then they can dispute it early and it can be sorted out before it's too late. It makes things more democratic and encourages students to take greater responsibility for their own learning because they have access to information that they otherwise wouldn't (at least not in as accessible and flexible a form). The display of grades and especially feedback for all the class' work is another case in point.
For the same reason I always include an assignment link for every piece of homework that gets assigned to the class - whether or not it is an online one (most of them are offline). I am a language teacher and sometimes students have comprehension problems in understanding the requirements of the teacher. If students need to check up a detail about the homework they can do so on the website rather than coming to me - this frees up my time to help students in more substantial and important ways.
For these reasons I can see a need for indicating on the website whether a submission for an offline assignment is on time or late. This would give even more feedback to the student regarding his work, other than the grade and qualitative feedback. Of course, this would also require that the module be modified to allow the manual input of this information. Martin I know how busy you are and also that this is probably not that important a feature in the scheme of things, but nonetheless it would improve the module considerably I think.
Until such functionality may or may not be included in moodle, I would agree that it would be better to remove the "Last modified" date as it is quite confusing and misleading in an offline assignment methinks. I use offline assignments mainly for work submitted on paper. As it stands now, if I give the feedback after the due date, the "Last modified" date is shown as being late, which gives the appearance that the work was submitted late, which is not correct - and of course I always do the feedback after the due date, never before.
I'd be interested in any other comments on this.
PS Thanks Martin for a great resource for educators and especially for its commitment to social constructivist modes of learning. 
Tim.
