Yeah that should perhaps suggest to you that the person you are addressing is not "lying".
Are you sure you're looking at the same article linked from this post? I'm seeing "October 30, 2023" at the top and "Monday, October 30, 2023" at the end.
I use NoScript, if you browse the linked page with JS disabled by default, it says "May 19, 2021" at the end.
If you allow JS for "thefp.com", it is indeed updated to today's date.
