Alternative Managed API:

If you need to get the time from a domain controller:

    using System.DirectoryServices.ActiveDirectory;

    DomainControllerCollection controllers = Domain.GetCurrentDomain().DomainControllers;
    foreach (DomainController c in controllers)
        Console.WriteLine(c.CurrentTime);
