IXR_Date->getIso returning incorrect data

[devlogic]

After several weeks of wondering why posts via xmlrpc were incorrectly showing up in the "future posts" section, I think I've discovered a bug in the returned data from IXR_Date->getIso: While parseIso is getting the timezone from the passed ISO date data, getIso is not returning the timezone, causing a mis-calculation wherein the post_date_gmt variable is padded by the TZ offset twice. Adding ".$this->timezone" into the return statement on line 628 of wp-includes/class-IXR.php seems to fix the problem.

This "bug" is present in the nightly build for 2005-12-07.
