[OS X TeX] Package "draftwatermark" -- adding date-time stamp

[John B. Thoo]

Hi.  I'd like to add a date-time stamp to "draftwatermark"; I'm using pdflatex.  In

<http://mirror.hmc.edu/ctan/macros/latex/contrib/draftwatermark/draftwatermark.pdf>

it states, "Other features available as options in draftcopy (e.g., the possibility of time- stamping the watermark text) can be obtained working on the watermark text itself."

How do I do this?  Thanks.

---John.
