We are developing a LMS. If a teacher ends a meeting (or a lesson in our case) before predefined time, i want to give information to students that the lesson has ended. I can get end date of meeting by connect web servies but in that list, the end time shows meetings ending time which was set before.
You can get that information from webapp too.. You need to go to Reports--> By Session reports and you will get all the info that you require for every session you had in that meeting room:
Hope this helps!
