Hi,
$zfDate1->compareDate($zfDate2) === 0 VS
$zfDate1->get('yyyyMMdd') === $zfDate2->get('yyyyMMdd')
Loop using if($zfDate1->compareDate($zfDate2) === 0)

The difference is huge, using comparators like ===, < or > on the date's
string is about 4 to 5 times faster than using e.g. compareDate.
So why not compare the string's in compareDate method ?
