// Subtract 10 minutes, making the date 10 minutes in the past.
$dt->AddSeconds(-600);

// Is the date/time older than 10 seconds?
$b = $dt->OlderThan(10, 'seconds');
echo 'Older than 10 seconds: ', ($b ? 'true' : 'false'), "\n";

// Is the date/time older than 5 minutes?
$b = $dt->OlderThan(5, 'minutes');

// Is the date/time older than 15 minutes?
$b = $dt->OlderThan(15, 'minutes');
echo 'Older than 15 minutes: ', ($b ? 'true' : 'false'), "\n";

$b = $dt->OlderThan(1, 'hour');
echo 'Older than 1 hour: ', ($b ? 'true' : 'false'), "\n";

$b = $dt->OlderThan(1, 'day');
