Dates are parsed incorrectly to Date properties. I've seen this bug before, but it had disappeared, possibly after installing an update. MediaWiki v 1.15.1 Semantic MediaWiki v 1.4.2
AFAIK this is a bug that has been fixed in SMW 1.4.3. Please update your installation. *** This bug has been marked as a duplicate of bug 20259 ***
