我在我的网站上做了一个帖子，想显示时间stemp为“3分钟前”，但这是我的功能，这是工作不正常。
mysql数据库 timestamp 更新后传递为 $time 就像 2018-04-15 09:00:02 这篇文章的制作时间仅仅是几分钟前的事，但在功能完成后的页面上的结果显示了这一点 9 Hours ago 请帮我显示正确的时间

public static function timeago($time){
   $time=strtotime($time);
   $periods = array("second", "minute", "hour", "day", "week", "month", "year", "decade");
   $lengths = array("60","60","24","7","4.35","12","10");
   $now = time();
     $difference = $now - $time;
     $tense= "ago";
     for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
       $difference /= $lengths[$j];
     }
     $difference = round($difference);
     if($difference != 1) {
       $periods[$j].= "s";
     }
   return "$difference $periods[$j] $tense ";
}
