Rounding PHP Time

[davefootball123]

I have a really easy php function that displays the current time + a certain amount of time...seen below. Is there a way to round the time to the nearest 10 minutes?

 

Thanks, Dave

$duration = date("hi A", strtotime("+45 minutes"))

10 mins is 600 seconds, so

 

 

$duration = strtotime("+45 minutes");
$duration = round($duration/600) * 600;
$duration = date('hi A', $duration);
