PHPExcel 读取日期出现一个万数问题

使用如下函数转化就可以了

function excelTime($days,$time=false)
{
    if(is_numeric($days))
    {
        $jd = GregorianToJD(1, 1, 1970);
        $gregorian = JDToGregorian($jd+intval($days)-25569);
        $gregorian = strtotime($gregorian);
        $gregorian = date("Y-m-d",$gregorian);
        return $gregorian;
    }
    return $time;
}
