Good afternoon, PostGres SQL queries using Canvas Data 2 for the public table, submissions column, submitted_at field returns inaccurate dates.

Below is an example of the results of a submitted_at field for a student in a class.   The top is null because the row was for a teacher and would not have submitted the assignment, the bottom row is for a student.  The date of the submitted_at is in 2023, however, the class did not start until 2024.

Here are the details of the start date of the course:

Course Start Date

Start

Course End Date

End

Is anyone else encountering this when using the submitted_at field in the submissions column in the public table of Canvas Data 2?  I welcome any insights you may have to offer.  Thank you so much.
