Graded discussion due dates set to 59 minutes are not setting seconds value to 59

CaelenLencioni

This behavior has been resolved and deployed to the production environment as of 8/13/25.

Description

• When creating a graded discussion and setting a due date with 59 minutes, the seconds field is not defaulted to 59 seconds.

Expected Behavior

• When entering a due date with minutes set to 59, the seconds should be automatically set to 59 seconds as with what happens with assignments.

• Quote from our guide: When you change a due time on an assignment, the seconds value defaults to 0 unless the minutes value is set to 59, in which case, the seconds are also set to 59

Workaround

• Add discussion due dates as 00 minutes instead of 59 (Example: Set 12:00pm instead of 11:59am)

Steps to Reproduce

1. Create or edit a graded discussion.

2. Set a due date with the minutes value set to 59 minutes.

3. Navigate to the discussions assignment object API and note that due dates seconds value is 00 instead of 59.
