We are using the Perl program listed on the SAA's Tools and Helper Files webpage, at https://www.archivists.org/saagroups/ead/tools.html . The program is called tri-XMLdate-normalizer.pl ( http://monkey.org/%7Ecaz/TRI-scripts/tri-XMLdate-normalizer.pl ) and works beautifully. Once you have it set up, which is quite easy once you understand how the Perl processor works, you can normalize (@normal="iso8601 value") dates in a finding aid within minutes. Good luck.
