How to convert a 13 digit Unix Timestamp to Date and time?

问题

I have this 13 digit timestamp 1443852054000 that i want to convert to date and time but dont succeed. I have tried this codes:

echo date('Y-m-d h:i:s',$item->timestamp);

doesnt work for me and also this

$unix_time = date('Ymdhis', strtotime($datetime ));

and this :

$item = strtotime($txn_row['appoint_date']); 
<?php echo date("Y-m-d H:i:s", $time); ?>

what should i use?

回答1:

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.g
echo date('Y-m-d h:i:s',1443852054000/1000);
// shows 2015-10-03 02:00:54

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 06:00:54

You may want to set the default timezone to avoid any warnings

date_default_timezone_set('Europe/Lisbon');

NOTE:

More about php date and time at php the right way

回答3:

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));
