Especially note Zend_Date::DATES, since this format specifier has
a unique property within Zend_Date as an
input format specifier. When used as an input format for
$part, this constant provides the most flexible acceptance of a
variety of similar date formats. Heuristics are used to automatically extract dates from
an input string and then "fix" simple errors in dates (if any), such as swapping of
years, months, and days, when possible.
