Change the "date" field
I need to order items by date (of publication), but currently Zotero only saves the year of a reference and not the month or date. Is there a way to manually add the exact date in the "date" field and if yes, what format should I use (e.g. DD-MM-YYYY)?
The safest is to use ISO dates, i.e. YYYY-MM-DD, but things like "15 Jun 2012" "December 15, 2001" etc. will work, too. I'm not sure if dates in French (i.e. something like "23 février 2005") will work on a French installation of Zotero, you'd have to try. Where applicable, Zotero also understands "today", "yesterday" and "tomorrow" (those I'm pretty sure in English only).
