If a property of type::Date (submittedOn for example) is created and then assigned a single value of a single year e.g:

[[submittedOn::2011]] 

then the value is not parsed correctly. The problem is in datavalues/SMW_DV_Time.php:149 and is the MediaWiki wfTimestamp() function. It doesn't correctly parse the year, but returns a value anyway. I did a quick test:

if ( $timeStamp !== false && $timeStamp != 19700101003332 ) {

and that fixed the problem. Obviously it's not a good solution, the wfTimestamp function probably needs to be fixed.
