Some help pages are site-specific. In particular, on non-English sites, the content of help pages is written (translated) obviously later than the original sources.
To detect outdated pages (for example, we can compare the dates on English and non-English sites), the last update timestamp would be really helpful. Some pages (such as moderator-related help) cannot be compared with other sites, because they are not visible if you don't have moderator privileges on that site.
Therefore, please add the last update date somewhere to help pages.
We have at least one page with a published update date, but that page is actually located on a different URL than other help pages. However, it's referenced from the Help Center. It's the Code of Conduct and the update text is located at the bottom of the content of the page (above the footer) and reads (for example):
Last update: 2023-05-31
