How to convert a 13 digit Unix Timestamp to Date and time?
This timestamp is in milliseconds, not in seconds. Divide it by 1000 and use date function:
echo date('Y-m-d h:i:s', $item->timestamp / 1000);// e.gecho 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.
$timestamp = 1443852054000;echo date('Y-m-d h:i:s', floor($timestamp / 1000));
You can achieve this with DateTime::createFromFormat.
Because you've a timestamp with 13 digits, you'll have to divide it by 1000, in order to use it with DateTime, i.e.:
$ts = 1443852054000 / 1000; // we're basically removing the last 3 zeros$date = DateTime::createFromFormat("U", $ts)->format("Y-m-d h:i:s");echo $date;//2015-10-03 06:00:54DEMO
