Skilljar surfaces a course level setting that can be enabled to display a course's duration on the course tile. You can either calculate course time automatically based on lesson time, or manually enter in a time to surface on a course tile.
Here's how to enable this setting:
1. On the Dashboard, click on Course Management
2. Click on the course
3. Expand Settings, then scroll down to Course Time
4. Check the box "Display course and lesson time"
5. Either allow Skilljar to automatically calculate time based on Lesson times entered, or check the box "Manual course time override" and enter the duration in the Course Time Text String input field.
6. Click Save
