Comment 6 for bug 683953

Yuck, a whole bunch more of Marisa's modify_xml tasks ran after we started this discussion (they'd already been submitted, but were held up by the catalog backlog until last night). We still have all these with invalid dates:

http://www.us.archive.org/metamgr.php?&srt=updated&ord=desc&w_date=*-*&w_identifier=classschedul*&fs_date=on&fs_identifier=on&fs_mediatype=on&fs_format=on&fs_collection=on&fs_curatestate=on&fs_noindex=on&off=0&lim=25

And Jeff, when making changes like this, can you please use modify_xml.php instead of editxml, so that the task history shows the changes?
