Subject Re: Updating source files with copyright dates
Date Fri, 20 Jan 2012 21:40:21 GMT
No. See http://www.copyright.gov/circs/circ1.pdf. You should only change
the copyright for the things you modify. My understanding is that an
inaccurate date can invalidate your copyright as the length of the
copyright is determined for the date of first publication. When you make
changes only those changes start from the new date.
