把下面代码放到主题的module.php文件中:

<?php
//日期格式化
function ea_timeago($ptime) {
    $ptime = strtotime($ptime);
    $etime = time() - $ptime;
    if ($etime < 1) return '刚刚';
    $interval = array (
        12 * 30 * 24 * 60 * 60  =>  date('Y-m-d', $ptime),
        30 * 24 * 60 * 60       =>  date('m-d', $ptime),
        7 * 24 * 60 * 60        =>  date('m-d', $ptime),
        24 * 60 * 60            =>  '天前',
        60 * 60                 =>  '小时前',
        60                      =>  '分钟前',
        1                       =>  '秒前'
    );
    foreach ($interval as $secs => $str) {
        if ($etime < 7 * 24 * 60 * 60){
            $d = $etime / $secs;
            if ($d >= 1) {
                $r = round($d);
                return $r . $str;
            }
        } else {
            return $str;
        }
    };
}?>
