// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$dt = new CkDateTime();

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

// Subtract 10 minutes, making the date 10 minutes in the past.
$dt->AddSeconds(-600);
print '10 minutes ago: ' . $dt->getAsTimestamp(true) . "\n";

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

// Is the date/time older than 5 minutes?
$b = $dt->OlderThan(5,'minutes');
print 'Older than 5 minutes: ' . $b . "\n";

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

// Is the date/time older than 1 hour?
$b = $dt->OlderThan(1,'hour');
print 'Older than 1 hour: ' . $b . "\n";

// Is the date/time older than 1 day?
