Blog post date error

The author line that displays under the blog title seems to show a date and the author name. However, the date is coming up wrong. Is there a way to either remove the date or modify the format of the date?
This is the format that is showing for today’s date of 6/16/2023: 15/20/2316 by author name

Hi Earl. I’m not sure I understand. Is that related to s2Member? What blog is that?
