Demonstrates how to query an NTP server to get the current date/time.

Note: This feature was added in Chilkat v9.5.0.96.

Chilkat2 PHP

<?php

use Chilkat2\DateTime;
use Chilkat2\JsonObject;

// 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 JsonObject();
$json->UpdateString('ntp_server', 'pool.ntp.org');

// Query the NTP server for the current date/time.
$dt = new DateTime();
try {
    $dt->SetFromNtpServer($json->Emit());
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Show the date/time in various formats..
$bLocalTime = true;
echo $dt->GetAsTimestamp($bLocalTime), "\n";
echo $dt->GetAsRfc822($bLocalTime), "\n";
echo $dt->GetAsUnixTime($bLocalTime), "\n";

// Sample output:

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