This timestamp is in milliseconds, not in seconds. Divide it by 1000 and use datefunction:
此时间戳以毫秒为单位，而不是以秒为单位。除以 1000 并使用date函数：
echo date('Y-m-d h:i:s', $item->timestamp / 1000);
// e.g
echo date('Y-m-d h:i:s',1443852054000/1000);
// shows 2015-10-03 02:00:54

A 13 digit timestamp is used in JavaScript to represent time in milliseconds. In PHP 10 a digit timestamp is used to represent time in seconds. So divide by 1000 and round off to get 10 digits.
JavaScript 中使用 13 位时间戳来表示以毫秒为单位的时间。在 PHP 10 中，数字时间戳用于表示以秒为单位的时间。所以除以 1000 并四舍五入得到 10 位数字。
$timestamp = 1443852054000;
echo date('Y-m-d h:i:s', floor($timestamp / 1000));

You can achieve this with DateTime::createFromFormat.
您可以使用DateTime::createFromFormat实现这一点。
Because you've a timestampwith 13 digits, you'll have to divide it by 1000, in order to use it with DateTime, i.e.:
因为你有一个timestampwith 13 digits，你必须将它除以1000，才能使用它 with DateTime，即：
$ts = 1443852054000 / 1000; // we're basically removing the last 3 zeros
$date = DateTime::createFromFormat("U", $ts)->format("Y-m-d h:i:s");
echo $date;
//2015-10-03 06:00:54
