You can also use DateInterval object

<?php
    $date = new DateTime('Y-m-d H:i:s');
    $date->sub(new DateInterval('PT10H30S'));
    echo $date->format('Y-m-d H:i:s');?>

Answer 3

You can use DateInterval

$date = new DateTime();
$interval = new DateInterval("PT15M");
$interval->invert = 1;
$date->add($interval);
echo $date->format("c") . "\n";

Following is the way you can add days / hours / minutes / sec to current time

  $addInterval = date('Y-m-d H:i:s', strtotime("+$days days $hours hours $minute minute $sec second", strtotime(currentTime)));

echo date('Y-m-d H:i:s', strtotime('-15 minutes'));
