Socket programming .net timestamp options

I am writing a socket application in c# to talk to a unix device. I am using TCP/IP and my program looks something like the below. The below is just snippets from the whole code..

socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.Connect(Configuration.headend1.remoteIP);
socket.Send(packet_complete);
socket.Close();

I was able to get an example of 1 command in bytes,using wireshark/ethereal network analyzer, that the unix device is expecting.I found out using wireshark that the unix device is expecting a timestamp(or i think it is a timestap) under the Transmission protrocol level options. If I look under wire shark under the Transmission protocol level heading I see a new thing under options(Timestamps: TSval 18139934, TSecr 533285028 and NOP) as show below-

Transmission Control Protocol, Src Port: 15100 (15100), Dst Port: 33526 (33526), Seq: 1, Ack: 17, Len: 0

        [This is an ACK to the segment in frame: 25]
        [The RTT to ACK the segment was: 0.201174000 seconds]

The problem is that when I send out my code using socket programming, I dont see the time stamp or options field in wireshark. All 12 bytes are missing. How do i add this? I know there are socketoptions() function but I dont know how to use it. Any help will be appreciated.
Thanks
