php excel reader 读取时间字段出错，哪位高手会弄得

$row = 1;
$handle = fopen("test.csv","r");
while ($data = fgetcsv($handle, 1000, ",")) {
    $num = count($data);
    echo "<p> $num fields in line $row: <br>\n";
    $row++;
    for ($c=0; $c < $num; $c++) {
        echo $data[$c] . "<br>\n";
    }
}
fclose($handle);

#我用上面的代码获取
#date
#2011-4-21
#的数据能正常获取

#你的问题怎么解决的？
