Meziantou.Framework.NtpClient

An NTP client library for querying NTP servers to retrieve accurate network time. Supports NTPv3 and NTPv4.

Features

  • NTPv3 and NTPv4: Configurable protocol version
  • Clock offset calculation: Computes the time difference between client and server
  • Round-trip delay: Measures network round-trip time
  • Async/await: Fully asynchronous API with cancellation support
  • OpenTelemetry: Built-in ActivitySource tracing for NTP queries

Usage

using Meziantou.Framework.Ntp;

// Query an NTP server using NTPv4 (default)
using var client = new NtpClient("pool.ntp.org");
var response = await client.QueryAsync();

Console.WriteLine($"Server time: {response.TransmitTimestamp}");
Console.WriteLine($"Clock offset: {response.ClockOffset}");
Console.WriteLine($"Round-trip delay: {response.RoundTripDelay}");
Console.WriteLine($"Stratum: {response.Stratum}");

Using NTPv3

using var client = new NtpClient("pool.ntp.org", new NtpClientOptions
{
    Version = NtpVersion.V3,
});
var response = await client.QueryAsync();

Cancellation and timeout

using var cts = new CancellationTokenSource(TimeSpan.FromSeconds(10));
using var client = new NtpClient("time.google.com");
var response = await client.QueryAsync(cts.Token);

Custom port

using var client = new NtpClient("localhost", new NtpClientOptions
{
    Port = 12345,
});
var response = await client.QueryAsync();
