Example #1 DateTime::setTimestamp() example

Stil obiect-orientat

<?php
$date 
= new DateTime();
echo 
$date->format('U = Y-m-d H:i:s') . "\n";

$date->setTimestamp(1171502725);
echo 
$date->format('U = Y-m-d H:i:s') . "\n";
?>

Stil procedural

<?php
$date 
date_create();
echo 
date_format($date'U = Y-m-d H:i:s') . "\n";

date_timestamp_set($date1171502725);
echo 
date_format($date'U = Y-m-d H:i:s') . "\n";
?>

Exemplele de mai sus vor afișa ceva similar cu:

1272508903 = 2010-04-28 22:41:43
1171502725 = 2007-02-14 20:25:25

Note

Using the Unix timestamp format to construct a new DateTime object is an alternative when using PHP 5.2, as shown in the example below.

Example #2 DateTime::setTimestamp() alternative in PHP 5.2

<?php
$ts 
1171502725;
$date = new DateTime("@$ts");
echo 
$date->format('U = Y-m-d H:i:s') . "\n";
?>

Exemplul de mai sus va afișa ceva similar cu:

1171502725 = 2007-02-14 20:25:25

When the exact time is important then it is important to note the difference between this and the UnixTimeStamp. The function will change the timestamp if necessary to take into account the daylight savings time.
e.g. Working with the 'Europe/London' timezone and setting the DateTime object to a timestamp of 1288486753 will result in the function automatically altering it to 1288490353.
This is because it is taking the fall time instead of the summer time (they will both be Sun, 31-Oct-2010 01:X:Y (I didn't check the hour and minute)).
Sincerely,

When you need to manipulate a unix timestamp like field (seconds since 1970-01-01) that may be greater than the drop dead date of 2038-01-19.

<?php

function secs2date($secs,$date)
    {
    if (
$secs>2147472000)    //2038-01-19 expire dt
       
{
       
$date->setTimestamp(2147472000);
       
$s=$secs-2147472000;
       
$date->add(new DateInterval('PT'.$s.'S'));
        }
    else
       
$date->setTimestamp($secs);
    }

function
date2secs($date,$datebeg)
    {
   
$diff = $datebeg->diff($date);
   
$secs=$diff->format('%a') * (60*60*24);  //total days
   
$secs+=$diff->format('%h') * (60*60);     //hours
   
$secs+=$diff->format('%i') * 60;              //minutes
   
$secs+=$diff->format('%s');                     //seconds
   
return $secs;
    }

$datebeg = new DateTime('1970-01-01');
$date=new dateTime();

$secs=2017472000//2033-12-06 08:53:20
secs2date($secs,$date);
$dt=$date->format('Y-m-d H:i:s');
echo
$dt."<br>";
$sec2=date2secs($date,$datebeg);
echo
'(1) ',$sec2,'***',$secs,'<br>';

$secs=2397472000; //2045-12-21 12:26:40
secs2date($secs,$date);
$dt=$date->format('Y-m-d H:i:s');
echo
$dt."<br>";
$sec2=date2secs($date,$datebeg);
echo
'(2) ',$sec2,'***',$secs,'<br>';
?>

If your PHP version is lower than 5.3 then you can use this class to be able to use the functions "setTimestamp" and "getTimestamp":

<?php

class MyDateTime extends DateTime
{
    public function
setTimestamp( $timestamp )
    {
       
$date = getdate( ( int ) $timestamp );
       
$this->setDate( $date['year'] , $date['mon'] , $date['mday'] );
       
$this->setTime( $date['hours'] , $date['minutes'] , $date['seconds'] );
    }
   
    public function
getTimestamp()
    {
        return
$this->format( 'U' );
    }
}

$date = new MyDateTime();
$date->setTimestamp( $someTimestamp );

echo
$date->format( 'd/m/Y H:i:s' );

?>
