Actually last_modified_at is a Jekyll plugin and I found out that I don’t need to provide a date time for this field, if I leave it empty and host my site locally, when I visit this page in my local it can display the page’s update time correctly:

Update: this feature now works sometimes in GitHub Pages, if above change doesn’t work, then following update needs to be considered.

So, I guess this is how it works - this Jekyll plugin can put this page’s last modified time property into this Updated field when it renders this page.

It works like a charm right? Just add this field then everytime when I update a page, its Updated field will be updated automatically. As this is what it behaves in my local. That’s how it’s supposed to work everywhere.

BUT!!! Strange behaviour noticed - it works in my local, it doesn’t work in my GitHub page after I pushed my code. If I enable this last_modified_at field in a page and leave it blank, in GitHub page there’s no Updated section at all.

Then I did some online search and got an answer from here, it clearly indicates that - this plugin doesn’t work with GitHub Pages. Well, there’s also a workaround - manually update that field. 😐 Hmmmm… I don’t want to manually update that field, that’s why it’s a plugin feature.

For now I will take that suggested workaround by using a VS Code plugin to generate current date time and manually update this field. Will look into that “Travis CI” approach later.
