What problem are you trying to solve with Submitty
The late submission warning test is currently failing due to unknown issues, and it is commonly flaky around time changes.

Describe the way you'd like to solve this problem
The test should be re-written and pass consistently without being flaky. You should test all facets of the late submissions, if possible.

You can use the existing tests as a basis to start, but they should be substantially re-written in order to pass effectively.
