(Mono C#) Get Current Date/Time from NIST Time ServerDemonstrates using Chilkat Socket to connect to an NIST time server and (using the old Time Protocol (RFC 868)), will read the current GMT time. Note: This is not necessarily the very best means for getting the current date/time. The most commonly used time protocol is the Network Time Protocol (RFC-1305).
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Socket socket = new Chilkat.Socket(); // Connect to an NIST time server and read the current date/time int maxWaitMs = 4000; bool useTls = false; bool success = socket.Connect("time-c.nist.gov",37,useTls,maxWaitMs); if (success != true) { Debug.WriteLine(socket.LastErrorText); return; } // The time server will send a big-endian 32-bit integer representing // the number of seconds since since 00:00 (midnight) 1 January 1900 GMT. // The ReceiveInt32 method will receive a 4-byte integer, but returns // true or false to indicate success. If successful, the integer // is obtained via the ReceivedInt property. bool bigEndian = true; success = socket.ReceiveInt32(bigEndian); if (success != true) { Debug.WriteLine(socket.LastErrorText); return; } Chilkat.CkDateTime dt = new Chilkat.CkDateTime(); dt.SetFromNtpTime(socket.ReceivedInt); // Show the current local date/time bool bLocalTime = true; Debug.WriteLine("Current local date/time: " + dt.GetAsRfc822(bLocalTime)); maxWaitMs = 10; socket.Close(maxWaitMs); |
