// 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");

$dateTime = new CkDateTime();

$dateTime->SetFromCurrentSystemTime();

print 'Current time: ' . $dateTime->getAsTimestamp(false) . "\n";

$dateTime->AddSeconds(1);
print 'Current time + 1 second: ' . $dateTime->getAsTimestamp(false) . "\n";

$dateTime->AddSeconds(-2);
print 'Current time - 1 second: ' . $dateTime->getAsTimestamp(false) . "\n";

// Add 30 days (60 * 60 * 24 * 30)
$dateTime->AddSeconds(60 * 60 * 24 * 30);
print 'Current time + 30 days: ' . $dateTime->getAsTimestamp(false) . "\n";
