We highly recommend that you do not change your time zone once you set it. There may be a situation where someone is traveling to a different city for a period of time during the term and they would like to change their time zone to the city they are traveling to. This is fine. However, you must realize that when you change your time zone, the time stamp on all of your assignments changes to the new time zone. It is possible that some assignments that were submitted on time could be marked late because changing the time zone also changed the submission time of the assignments. Please keep this in mind if you decide to change your time zone during the term.
