(Xojo Plugin) Get Current Date/Time from NIST Time Server

Demonstrates 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.

Dim socket As New Chilkat.Socket

// Connect to an NIST time server and read the current date/time
Dim maxWaitMs As Int32
maxWaitMs = 4000
Dim useTls As Boolean
useTls = False
Dim success As Boolean
success = socket.Connect("time-c.nist.gov",37,useTls,maxWaitMs)
If (success <> True) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

// 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.
Dim bigEndian As Boolean
bigEndian = True
success = socket.ReceiveInt32(bigEndian)
If (success <> True) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

Dim dt As New Chilkat.CkDateTime
success = dt.SetFromNtpTime(socket.ReceivedInt)

// Show the current local date/time
Dim bLocalTime As Boolean
bLocalTime = True
System.DebugLog("Current local date/time: " + dt.GetAsRfc822(bLocalTime))

maxWaitMs = 10
success = socket.Close(maxWaitMs)
