Your course's time zone determines:
As an example, if your course uses the Central time zone and you create an assignment that is due on September 15, the default deadline for that assignment is 11:59 p.m. Central time on September 15. Any assignments that are not submitted by that time are considered to be late. This also means that any students who are outside the Central time zone must submit the assignment in Central time. For example:
For any student who does not submit the assignment by 11:59 p.m. Central time, regardless of the student's time zone, the MyLab flags the submission as late.
As far as archiving a course is concerned, the MyLab automatically archives a course at 11:59 p.m. in the course's time zone on the course's end date.
You
You don't need to track whether you are in Standard or Daylight Savings Time. The MyLab calculates these times and offsets as needed. For example, a course using Central time would display (GMT –6:00) Central Time during Standard Time. In Daylight Savings Time, the course would display (GMT –5:00) Central Time.
