Query NTP Server for Current Date/Time

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

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

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // 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.
  final json = CkJsonObject();
  json.updateString('ntp_server', 'pool.ntp.org');

  // Query the NTP server for the current date/time.
  final dt = CkDateTime();
  try {
    dt.setFromNtpServer(json.emit());
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Show the date/time in various formats..
  final bLocalTime = true;
  print(dt.getAsTimestamp(bLocalTime));
  print(dt.getAsRfc822(bLocalTime));
  print(dt.getAsUnixTime(bLocalTime));

  // Sample output:

  // 2023-10-31T09:43:27-05:00
  // Tue, 31 Oct 2023 09:43:27 -0500
  // 1698745407
