Hi,
Is there a possibility to define an export file name of a heading so
that the resulting file contains a date-stamp?
What I want to achieve:
*** My Report
:PROPERTIES:
:EXPORT_FILE_NAME: (format-time-string "%Y-%m-%d") Project Status.html
:END:
... which results in the file: "2018-02-07 Project Status.html"
No, this does not work this way at the moment (Orgmode from git
maint, d3f7309cb from 9 weeks ago).

Yes, you cannot do that (How would Org know that you do not want to name
your file literally like that? :)).
Also you do not need to (should not?) provide the file extension there..
the correct extension is added based on the exporter you use.
That said, I quickly tested this out, and it works:
(defun modi/org-advice-prefix-export-file-name-with-date (orig-fun &rest
args)
"Prefix the output file name with current date."
(let* ((date-format "%Y-%m-%d") ;Customize this variable as you like
(date-file-separator "-") ;Customize this variable as you like
(orig-output-file-name (apply orig-fun args))
(orig-output-dir (file-name-directory orig-output-file-name))
(orig-output-just-file-name (file-name-nondirectory
orig-output-file-name))
(date (format-time-string date-format (current-time))))
(concat orig-output-dir date date-file-separator
orig-output-just-file-name)))
(advice-add 'org-export-output-file-name :around
#'modi/org-advice-prefix-export-file-name-with-date)
;; (advice-remove 'org-export-output-file-name
#'modi/org-advice-prefix-export-file-name-with-date)
After evaluating the above, current date will be prefixed to the exported
file name, whether you export the whole file or just a subtree.

Use an `eval' macro.
In a more recent version than you use, this works:
* abc
:PROPERTIES:
:EXPORT_TITLE: {{{etitle(my title)}}}
:END:
#+macro: etitle (eval (concat (format-time-string "%Y-%m-%d") " " $1))
...
You might need to quote the `$1'. The quoting convention was changed recently.
HTH,
Chuck

That works for EXPORT_TITLE!
So I tried for EXPORT_FILE_NAME, but it doesn't work there, because
org-export-output-file-name should be getting called internally *before*
the macro expansion is done.

I missed that.
Further, `org-export-file-name' gets called before `org-export-as' so there is no hope of using export hooks or filters or other gambits like that.
I don't see a clean way to do date stamp the file name without writing your own export-to-file function that handles date-stamping the file arg sent to `org-export-to-file' or replacing/advicing `org-export-file-name' to do that.
