Used Javascript in Document Actions to create dynamic watermark to display print date, however it doesn't work in Acrobat Reader, even though Javascript is enabled. Is it because watermarks cannot be created in Reader?

Below is the script that I used under "Document Will Print".  when I tested using Adobe Acrobat Pro DC it worked great. When I tested using Adobe Reader XI, the date did not show up, even though JavaScript was enabled.  Any suggestions?

this.addWatermarkFromText({

cText: util.printd('mmm d, yyyy h:MM tt', new Date()),

nHorizAlign: app.constants.align.center,

nVertAlign: app.constants.align.bottom

});
