How did you generate the above data? Try this one:
<?php
$value="2007-02-07 05:54:17 UTC
2007-02-07 20:12:06 UTC
2007-02-07 20:50:31 UTC
2007-02-07 20:56:25 UTC
2007-02-07 20:56:32 UTC";
$res=explode('UTC', ($value));
for($i=0; $i<sizeof($res)-1; $i++){
			echo date("Y-m-d G:i", strtotime($res[$i]))."<br>";
		
}
?>

It was may mistake first see the updated comment now there you must change the time format g to G see below:

for($i=0; $i<sizeof($res)-1; $i++){
			echo date("Y-m-d G:i", strtotime($res[$i]))."<br>";
		
}

If these are strings, just do substr() to get the first 16 characters..
echo substr($line, 0, 16);  // abcd

See http://www.laprbass.com/RAY_temp_rgb192.php

This is all covered in the article here:
http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/A_201-Handling-date-and-time-in-PHP-and-MySQL.html

Take careful note of the date_default_timezone.  You need to understand this with absolute certainty!

<?php // RAY_temp_rgb192.php
error_reporting(E_ALL);


// THIS MATTERS - A LOT!
date_default_timezone_set('UTC');


// TEST DATA
$arr = array
( '2007-02-07 05:54:17 UTC'
, '2007-02-07 20:12:06 UTC'
, '2007-02-07 20:50:31 UTC'
, '2007-02-07 20:56:25 UTC'
, '2007-02-07 20:56:32 UTC'
)
;

// FORMATTING PATTERN
$pat = 'Y-m-d H:i';

foreach ($arr as $inp)
{
    $out = date($pat, strtotime($inp));
    echo "<br/>$inp ==> $out";
}

I prefer the date outputs rather than substr because I want to modify date output (but I did not ask this).  All answers are good thanks
