Yes, I did, but I didn't know how to get it to print the date and time that I ran pdflatex.

I'm still using TeX Live 2009.  I will upgrade to TeX Live 2012 ASAP.  Thanks.

Thanks.  I had to make only smalls modifications, viz., (i) I used \SetWatermarkScale, (ii) I put in a negative \vspace, and (iii) I changed the fontsize.


      {\fontsize{12}{6}\selectfont \today, \printtime}

Thank you both, Herb and Peter, for your help.
