I don't know jekyll or how the blog is set up.  Perhaps timestamps need
to be updated in the post file.  Please fix up when applying.

Right, I only had to add

last_modified_at: 2017-02-15 15:49:00 +0100

to the header.  So this will be also a nice example of how to update a
post after the fact!

Thanks for looking into it.

Weird that the blog engine relies on manual metadata rather than using
file timestamps.

I think the reason is that the file timestamps can change for unrelated reasons:
adding a new permalink or fixing a typo may not be worth of adding the
"updated Feb 16, 2017" note on the page.  Wordpress and the like probably
have a similar behavior, you just don't see it because it's hidden in a
database rather than part of a text file. :)
