[Koha] Fwd: koha: sort by year

Were you able to get the Sort by Publication/Copyright Date to work? For some reason, it's not working for me, and I've poked around the web, and I'm wondering if Koha sorts on 008/7-10 (fixed length data elements, date 1) instead of 260$c. Of course our records don't have anything in 008 but the 260$c field was looking pretty good! Thanks, Sally.
