Hi Thomas,

I've just pushed this functionality up to the main branch.  To make use
of it add the following to your Emacs config.

  (setq org-babel-hash-show-time t)

It works for me in some simple tests, and I can confirm that with this
variable set to nil, I get no new failures in the Org-mode test suite,
so it shouldn't introduce any problems.

Thanks for suggesting this functionality,
