how can get DateTime From Internet (External Resource – Not From Server)

how can i get current time From Internet (External Resource – Not From Server)?
For Example From the Below WebSite :
i will redirect my pages to a Lock page after one month (by checking DateTime.Now) and in that page user should input activation code for comming back…
for some security reasons i want to get the current Date/Time From Out Of My Server…

thanks in advance

Method 1

I think this will help you out of it.Apply the below mentioned code for retrieving the date from Internet.

public static DateTime GetFastestNISTDate()
    var result = DateTime.MinValue;

    // Initialize the list of NIST time servers
    string[] servers = new string[] {

        // Try 5 servers in random order to spread the load
        Random rnd = new Random();
        foreach (string server in servers.OrderBy(s => rnd.NextDouble()).Take(5))
                // Connect to the server (at port 13) and get the response
                string serverResponse = string.Empty;
                using (var reader = new StreamReader(new System.Net.Sockets.TcpClient(server, 13).GetStream()))
                    serverResponse = reader.ReadToEnd();

                // If a response was received
                if (!string.IsNullOrEmpty(serverResponse))
                    // Split the response string ("55596 11-02-14 13:54:11 00 0 0 478.1 UTC(NIST) *")
                    string[] tokens = serverResponse.Split(' ');

                    // Check the number of tokens
                    if (tokens.Length >= 6)
                        // Check the health status
                        string health = tokens[5];
                        if (health == "0")
                            // Get date and time parts from the server response
                            string[] dateParts = tokens[1].Split('-');
                            string[] timeParts = tokens[2].Split(':');

                            // Create a DateTime instance
                            DateTime utcDateTime = new DateTime(
                                Convert.ToInt32(dateParts[0]) + 2000,
                                Convert.ToInt32(dateParts[1]), Convert.ToInt32(dateParts[2]),
                                Convert.ToInt32(timeParts[0]), Convert.ToInt32(timeParts[1]),

                            // Convert received (UTC) DateTime value to the local timezone
                            result = utcDateTime.ToLocalTime();

                            return result;
                            // Response successfully received; exit the loop



                // Ignore exception and try the next server
        return result;

Method 2

You can’t, not by using DateTime.Now. It is a property of the DateTime structure that can’t be overridden.

You can use an NTP server to get time (though there is not support in the BCL for one).

Method 3

Why not use a HttpRequest to query the RSS feed of a site which gives world time? Is this what you mean?

Method 4

Why would you want to get it from the internet, you would still be getting it from someone’s sever.

Method 5

You can get the DateTime using JavaScript

    myDate = new Date();
    myday = myDate.getDay();
    mymonth = myDate.getMonth();
    myweekday= myDate.getDate();
