I think there are 2 copyright statements mixed here :

- the copyright of the ASF license since it's a copyrighted document from the Apache Foundation. The date on the ASF license shouldn't be changed, except when it's adapted for a specific component (the "you must not reuse the project/product name" condition). For example the GPL license is copyrighted by the FSF with a date set to 1989, 1991 and this is never changed by projects released under the GPL (and actually they can't change it since the license of the GPL doesn't allow modifitions).

- the copyright statement of the file, i.e. the date of its creation/modification and the author of the code. I believe every contributor retains the copyright on the code submitted but may assign it to the ASF. I guess that's what happens most of the time and would explain why a single copyright statement serves 2 purposes.

copyright, everytime it changes we need to update the date?  I don't think
anyone pays attention to it on a day to day basis..  Sounds like we need
something like a maven plugin that checks each file, and if it has changed
post whatever the copyright date is, then updates it...

  Actually the copyright doesn't end in 2002 but starts in 2002, it's then
  valid for the lifetime of the author plus a minimum of 50 years after
  his death according to the Berne Convention.

  You are right though that some content submitted or modified this year
  doesn't have a copyright assigned in 2003.
