* Limitation : Only this format can be parsed %S, %M, %H, %d, %m, %Y

* @param $sDate(string) The string to parse (e.g. returned from strftime()).

* @return (array) Returns an array with the <code>$sDate</code> parsed, or <code>false</code> on error.

ただし、DateTime::createFromFormat は DateTime のオブジェクトを返すため、PHP < 5.3 ではまったく同じ結果を得ることができません (DateTime とまったく同じように動作する独自のクラスを作成する意思がない限り)。
