Using Dreamweaver
If you are using Dreamweaver, adding an automated modification
date is very simple. The date change occurs within Dreamweaver and
does not work if you are using other web editing programs.
Javascript Code
Example: Last updated
by Department Web Developer.
Cut and paste the code in between the lines
below. Be aware that you may not be able to see the date while
working on the document but it will display once it is uploaded
to the server if using modern browsers. Be sure to replace department with
the correct e-mail address and name.
