是的，您可以使用PHP实现这一点。

这是a function 来自@arnorhs：

$time = strtotime(\'2010-04-28 17:25:43\');

echo \'event happened \'.humanTiming($time).\' ago\';

function humanTiming ($time)
{

    $time = time() - $time; // to get the time since that moment
    $time = ($time<1)? 1 : $time;
    $tokens = array (
        31536000 => \'year\',
        2592000 => \'month\',
        604800 => \'week\',
        86400 => \'day\',
        3600 => \'hour\',
        60 => \'minute\',
        1 => \'second\'
    );

    foreach ($tokens as $unit => $text) {
        if ($time < $unit) continue;
        $numberOfUnits = floor($time / $unit);
        return $numberOfUnits.\' \'.$text.(($numberOfUnits>1)?\'s\':\'\');
    }

}

WordPress的方式实际上有很多。但WordPress自1.5.0版以来就有一个内置功能，这对于WordPress插件的开发非常方便：

<?php human_time_diff( $from, $to ); ?>

从现在开始显示注释的运行时间很简单，如下所示：

echo human_time_diff( get_comment_time( \'U\' ), current_time( \'timestamp\' ) ) .\' ago\';
