Ideally you would add the following:

Initially modified for use with MPlayer by A N Other on 4-2-1492
See detailed CVS changelog at http://cvs.mplayer.org

Date of any change. I personally find the initial modification and
current modification date to be sufficient.

That's why you can use CVS to indicate when the last change was done,
and the file itself to indicate when the first change was done.

Look at the Id tag of CVS and Subversion.
