Question

I am using facebook graph api to search for posts matching a particular query.But I cannot find any documentation about the time zone of the time stamp returned in the json format.

My query is this and the response the JSON arrray where each element has a timeStamp which looks like this :
2013-01-15T14:27:49+0000

How do I use this timeStamp ( without time zone information ) to display fb content on an external website:

 <snip>post content </snip> poster-profile image</snip>
   < snip> post created 5 minutes ago </snip> 

Edit : I am using the grails framework for the backend implementation. hence using php code to obtain timeStamp information would not be very easy

Edit 2 : I am using the search api to search over all publicly accessible posts, so I am not suing any access token.

Edit 3 : closing this question as a possible duplicate of this.

If you are using PHP, you may use this-

// DISPLAYS COMMENT POST TIME AS "1 year, 1 week ago" or "5 minutes, 7 seconds ago", etc...
function time_ago($date,$granularity=2) {
    $date = strtotime($date);
    $difference = time() - $date;
    $periods = array('decade' => 315360000,
        'year' => 31536000,
        'month' => 2628000,
        'week' => 604800, 
        'day' => 86400,
        'hour' => 3600,
        'minute' => 60,
        'second' => 1);

    foreach ($periods as $key => $value) {
        if ($difference >= $value) {
            $time = floor($difference/$value);
            $difference %= $value;
            $retval .= ($retval ? ' ' : '').$time.' ';
            $retval .= (($time > 1) ? $key.'s' : $key);
            $granularity--;
        }
        if ($granularity == '0') { break; }
    }
    return ' post created '.$retval.' ago';      
}
