note 88022 rejected from function.date-timezone-get by thiago

Note Submitter: fordiman at gmail dot com ---- According to the example here, there's a DateTime object native in PHP - but I can't find documentation on it. I think that's a pretty important thing to know about; it affects serialization and databasing, and could ease data passing by ensuring the right object is used to represent a given bit of data - so where are the docs?
