adding planted and last tended dates to pages in my digital garden

Why

I already have 'This page last updated: …' at the bottom of every page.

But I'd prefer it right at the top. Not too prominent/distracting, but I have some pretty old pages knocking around now and I'd like people to be aware that they might be outdated.

How

I have ctimes and mtimes on all files I believe. (That's from an extra package that I installed, right?)

So in theory I can use those.

It's a matter of (a) pulling them out and (b) being able to render them.

Pulling times out

I'm currently using just the date value that you get from :with-date. So I won't be able to get last modified in the same way.

I have custom properties I have named ctime and mtime. Possibly these are in the info plist that's passed in the org-html-template?

Rendering them

So the rendering is going to be somewhere in my somewhat sprawling publish.el - or at least that's where to start thinking about it.

I think I would put it in my override of org-html-template (of which I have a note to self saying that I shouldn't really be overriding it…)
