[php] Converting a UNIX Timestamp to Formatted Date String

Using PHP, I want to convert UNIX timestamps to date strings similar to this: 2008-07-17T09:24:17Z

How do I convert a timestamp such as 1333699439 to 2008-07-17T09:24:17Z?

This question is related to php unix-timestamp

The answer is

Try gmdate like this:

echo gmdate("Y-m-d\TH:i:s\Z", $timestamp);

use date function date ( string $format [, int $timestamp = time() ] )

Use date('c',time()) as format to convert to ISO 8601 date (added in PHP 5) - 2012-04-06T12:45:47+05:30

use date("Y-m-d\TH:i:s\Z",1333699439) to get 2012-04-06T13:33:59Z

Here are some of the formats date function supports

$today = date("F j, Y, g:i a");                 // March 10, 2001, 5:16 pm
$today = date("m.d.y");                         // 03.10.01
$today = date("j, n, Y");                       // 10, 3, 2001
$today = date("Ymd");                           // 20010310
$today = date('h-i-s, j-m-y, it is w Day');     // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.');   // it is the 10th day.
$today = date("D M j G:i:s T Y");               // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h');     // 17:03:18 m is month
$today = date("H:i:s");                         // 17:16:18

Assuming you are using PHP5.3 then the modern way of handling dates is via the native DateTime class. To get the current time you can just call

$currentTime = new DateTime();

To create a DateTime object from a specific timestamp (i.e. not now)

$currentTime = DateTime::createFromFormat( 'U', $timestamp );

To get a formatted string you can then call

$formattedString = $currentTime->format( 'c' );

See the manual page here

It is very important to set a default timezone to get the correct result

// set default timezone

// timestamp
$timestamp = 1307595105;

// output
echo date('d M Y H:i:s Z',$timestamp);
echo date('c',$timestamp);

Online conversion help: http://freeonlinetools24.com/timestamp

echo date('Y-m-d H:i:s', $timestamp/1000);

$unixtime_to_date = date('jS F Y h:i:s A (T)', $unixtime);

This should work to.

The DateTime class takes a string in the constructor. If you prefix the timestamp with a @-character you create a DateTime object with the timestamp. For formating use the 'c' format ... a predefined ISO 8601 compound format.

If could use the DateTime class like this ... set the right timezone or leave it out if you want a UTC time.

$dt = new DateTime('@1333699439');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('c');

I found the information in this conversation so helpful that I just wanted to add how I figured it out by using the timestamp from my MySQL database and a little PHP

 <?= date("Y-m-d\TH:i:s\+01:00",strtotime($column['loggedin'])) ?>

The output was: 2017-03-03T08:22:36+01:00

Thanks very much Stewe you answer was a eureka for me.

You can do like as.....

$originalDate = "1585876500";

echo $newDate = date("Y-m-d h:i:sa", date($originalDate));
