<?php

include("chilkat.php");

// Specify the NTP server domain.
// Information is passed in a JSON object to allow for any unanticipated future optional information that might need to be provided.
$json = new CkJsonObject();
$json->UpdateString('ntp_server','pool.ntp.org');

// Query the NTP server for the current date/time.
$dt = new CkDateTime();
$success = $dt->SetFromNtpServer($json->emit());
if ($success == false) {
    print $dt->lastErrorText() . "\n";
    exit;
}

// Show the date/time in various formats..
$bLocalTime = true;
print $dt->getAsTimestamp($bLocalTime) . "\n";
print $dt->getAsRfc822($bLocalTime) . "\n";
print $dt->GetAsUnixTime($bLocalTime) . "\n";

// Sample output:

// 2023-10-31T09:43:27-05:00
// Tue, 31 Oct 2023 09:43:27 -0500
