Not exactly a CodeIgniter question but native php but does anyone know how you round current time to nearest 15 minutes

I have some simple code displaying current time:

Code:
echo date('G:i');

Tried some formulas but haven't had much luck so far
example 18:27
should display 18:30

Cheers if anyone can help

Found this not sure if it will help.

Code:
$signintime = '4:32 pm';

define( 'SIGN_IN', $signintime);

function minutes_round ($hour = SIGN_IN, $minutes = 5, $format = "H:i")

{

    $seconds = strtotime($hour);

    $rounded = round($seconds / ($minutes * 60)) * ($minutes * 60);

    return date($format, $rounded);

}

// use example:

// echo minutes_round(); // returns 16:30

I've used this before.

$minute = date("i");
$multiplier = round($minute / 15);
echo $multiplier * 15;

Code:
function round_minutes($minutes, $precision = 15)

{

  return round($minutes / $precision) * $precision;

}

Code:
echo round_minutes(date('i'));

Great help guys, used timmahoney method in end(edit now using InsiteFX method), added switch so 17:59 will now go to 18:00.

Code:
$minute = date("i");

$nQuarter = round($minute / 15)* 15;

switch($nQuarter) {

    case 60:

 $ntime = date('G', strtotime(" +1 hours"));

 echo $ntime.':00';

        break;

    case 0:

    echo date('G').':00';

        break;

    default:

    echo date('G').':'.$nQuarter;

}

Actually looking at InsiteFX method probably works better as no need for switch

Final Code:

Code:
$ctime = date('G:i');

$minutes = 15;

$format = "G:i";

$seconds = strtotime($ctime);

$rounded = round($seconds / ($minutes * 60)) * ($minutes * 60);

echo date($format, $rounded);
