Your course's time zone determines the:
For example, if the course is in Central time and a student submission is sent to you at 10:00 a.m., the submission is time stamped 10:00 a.m. Central time.
For students in different time zones, the MyLab time stamps their submissions and Gradebook reports using the course's time zone. As an example, assume that the course is in Central time and that a student in Eastern time sent a submissions to you at 11:00 p.m. on September 15. Eastern time is one hour ahead of Central time. So, a 10:00 p.m. submission in Eastern time will be time stamped as a 9:00 p.m. submission in a course using Central time.
Depending on the time zones, a different time stamp can also cause a different date stamp. For example, assume that the course is in Central time and that a student submission is sent to you at 11:00 p.m. on September 15 in Pacific time. In this case, Central time is two hours ahead of Pacific time. This means that the submission will be date-and-time stamped as 1:00 a.m. on September 16.
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.
If you need to convert times across time zones, there are several time-zone conversion websites that you can find using your preferred search engine. Two of the more popular websites are:
