+Date helper standard_date()
+===========================
+
+:doc:`Date Helper <../helpers/date_helper>` function ``standard_date()`` is being deprecated due
+to the availability of native PHP `constants <http://www.php.net/manual/en/class.datetime.php#datetime.constants.types>`_,
+which when combined with ``date()`` provide the same functionality. Furthermore, they have the
+exact same names as the ones suppored by ``standard_date()``. Here are examples of how to replace
+it's usage:
+
+::
+
+	// Old way
+	standard_date(); // defaults to stanard_date('DATE_RFC822', now());
+
+	// Replacement
+	date(DATE_RFC822, now());
