Php displays wrong time

I have a php script that collects data with the current timestamp.

The timestamp in the mysql database is correct (giving the correct time and date), although on the front end it displays : in 5 hours

The script that generates this output looks like this:

function plural($num) {
    if ($num != 1)
    return "s";
}

function relative_date($date) {
    $diff = time() - strtotime($date);
    if ($diff>0) {
        if ($diff<60)
            return $diff . " second" . plural($diff) . " ago";
        $diff = round($diff/60);
        if ($diff<60)
            return $diff . " minute" . plural($diff) . " ago";
        $diff = round($diff/60);
        if ($diff<24)
            return $diff . " hour" . plural($diff) . " ago";
        $diff = round($diff/24);
        if ($diff<7)
            return $diff . " day" . plural($diff) . " ago";
        $diff = round($diff/7);
        if ($diff<4)
            return $diff . " week" . plural($diff) . " ago";
        return date("M j, Y", strtotime($date));
    } else {
        if ($diff>-120)
            return "Right now";
        if ($diff>-60)
            return "in " . -$diff . " second" . plural($diff);
        $diff = round($diff/60);
        if ($diff>-60)
            return "in " . -$diff . " minute" . plural($diff);
        $diff = round($diff/60);
        if ($diff>-24)
            return "in " . -$diff . " hour" . plural($diff);
        $diff = round($diff/24);
        if ($diff>-7)
            return "in " . -$diff . " day" . plural($diff);
        $diff = round($diff/7);
        if ($diff>-4)
            return "in " . -$diff . " week" . plural($diff);
        return date("M j, Y", strtotime($date));
    }
}

How can I get that to show me the correct ti开发者_JAVA百科me?

I have no idea what the problem is, maybe timezone settings. Check them in your PHP.ini and in your code
