Since I am versioning all by myself …

True but when you need an exam and you find a few copies lying on  
your desk, seemingly just what you need, you do want to check the  
compile date.

No, because all Adobe applications are banned from my computer. (Too  
invasive.)

However, yes, it would be good to have both dates. Because I tend to  
over-compile because I tend to lose the pdf.

That's the trouble: I am not getting any error. I am not getting  
anything … other than

This is a text body!

I even tried to move/copy

  \SourceFile{\jobname.tex}

to within the document. No error, no stamp that I can see.

So I must be missing something big!


Here is the console:
