Quest Learning Modules offer the ability to administer timed assignments, which may be useful for take home quizzes or time-restricted in-class exams. To use this setting, create a new assignment, select learning module (as this is the only type where this features is offered), and enter in the full window during which students have for this assignment. 
If you do not have learning module or Online exams offered as an assignment type, navigate to your grading scheme and add a new type (you can name it whatever you want, but the 'submit by' pull down needs to show learning module).
Below this you will be given the option to set the amount of time students will have once they progress past the instruction slide of the learning module. If you do not want your students to receive immediate feedback be sure to also check the 'test mode' box. You may set a window span (example: 10am-3pm) during which time students will have access to the assignment; however, once they start the set timer will be in effect.
