// Set to the current system date/time.
$dt->SetFromCurrentSystemTime();
print 'Now: ' . $dt->getAsTimestamp(1) . "\n";

// Add 10 minutes, making the date 10 minutes in the future.
$dt->AddSeconds(600);
print '10 minutes from now: ' . $dt->getAsTimestamp(1) . "\n";

// Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?

print 'Expires within 10 seconds: ' . $b . "\n";

// Does the date/time expire within 5 minutes?
