Dynamic timestamp or watermark

Question

All,
  I have read a lot of these forums and can't seem to locate one that relates to my problems.  Is their someone out there that can help me?
I am using Abode Acrobat Pro 9, I support the manufacturing floor.  I need to be able to put something on the PDF that when they print a PDF on the floor it automatically puts verbiage of "PRODUCTION COPY - VOID AFTER 30 DAYS" with the current print date and their logon information.
They will be printing from Reader, I have over 3000 prints that need to be updated.
Has anyone dealt with this before?
Please help!!!!

Sorry for the delay getting back to this I was pulled off to work on another problem.
  Alright getting back to the original problem, I was able to add the print date fairly easily with the code below.
// add form field to each page of the PDF
for (var pageNumber = 0; pageNumber < this.numPages; pageNumber++) { var dateStamp = this.addField("DateStamp","text",pageNumber,[2,2,400,12]); dateStamp.textSize=8; }
this.setAction("WillPrint", "var today = new Date(); var current_hour = today.getHours(); var current_minute = today.getMinutes(); this.getField('DateStamp').value = \"Date/Time Printed: \" + util.printd(\"dd/mmm/yyyy\",new Date()) + \" \" + current_hour + \":\" + current_minute;");
I tried to add this code below from the dynamic stamps to no avail. Below is what I tried, I was able to get the date but not the user name.
// add form field to each page of the PDF
for (var pageNumber = 0; pageNumber < this.numPages; pageNumber++) { var dateStamp = this.addField("DateStamp","text",pageNumber,[2,2,400,12]); dateStamp.textSize=8; }
this.setAction("WillPrint", "var today = new Date(); var current_hour = today.getHours(); var current_minute = today.getMinutes(); this.getField('DateStamp').value = \"Date/Time Printed: \" + util.printd(\"dd/mmm/yyyy\",new Date()) + \" \" + current_hour + \":\" + current_minute;");
event.value = (new Date()).toString();
AFDate_FormatEx("h:MM tt, mmm dd, yyyy");
event.value = "PRINTED BY" + ((!identity.name || identity.loginName != (event.source.source || this).Collab.user) ? (event.source.source || this).Collab.user : identity.name)
+ " at " + event.value;
I couldn't figure out where to put the application code from GKaiseril, otherwise I would have tried that also.  If anyone can point me in the right direction with what I’ve got and how to fix it I would greatly appreciate it.
