They have "Copyright 2010-2013" because those are the years in which the pages were edited by a person. This tells you the LAST time they were modified so that you can work out when the content transfers in to the public domain, which is something like 100 years later. Having a script automatically update them like that is misleading because the content WASN'T created the year you are claiming it was.
