\\u time（）函数是WordPress的内置函数，用于显示帖子创建的时间。

因此，如果要显示当前日期和时间，需要使用php函数date比如：

    <?php
// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone

$today = date("F j, Y, g:i a");                 // March 10, 2001, 5:16 pm
$today = date("m.d.y");                         // 03.10.01
$today = date("j, n, Y");                       // 10, 3, 2001
$today = date("Ymd");                           // 20010310
$today = date(\'h-i-s, j-m-y, it is w Day\');     // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date(\'\\i\\t \\i\\s \\t\\h\\e jS \\d\\a\\y.\');   // it is the 10th day.
$today = date("D M j G:i:s T Y");               // Sat Mar 10 17:16:18 MST 2001
$today = date(\'H:m:s \\m \\i\\s\\ \\m\\o\\n\\t\\h\');     // 17:03:18 m is month
$today = date("H:i:s");                         // 17:16:18

// and echo it out
echo $today;
?>
