Previously you could quite easily send a new post into the back of beyond by specifying an invalid date like the 30th Feb and this was very confusing. Sometimes it would seem to work and sometimes the post would end up very far in the past - depending on the mysql version and other factors. Fixes #17180 props jkudish. git-svn-id: http://core.svn.wordpress.org/trunk@21921 1a063a9b-81f0-0310-95a4-ce76da25c4cd
