If your students are taking your course in a different time zone, you can ask them to change their Canvas to the local time zone. Here is a video that shows students how to make that change. To fully take advantage of the automatic adjustments in Canvas, you as a professor should ideally set the due date in Canvas, rather than just include the time in descriptions.
If the following video is not showing up, copy and share the following link with them:

They should change it back to the campus local time (Central Time) when they return to campus.
