how to detect event not get trigger from last two minutes

I am working on live chat for admin and customer (nodejs+socketio+express). In between chat when customer waiting more than two minutes for admin response I need to show message to customer side "please try sometime later"

for example client getting response from this event

socket.on('Admin Response',function(msg){

});

How to track this event not get trigger from the last two minutes?

A simple way to do this is as follows :

var timeout=setTimeout(sendMessage,120000);

socket.on('Admin Response',function(msg){
    clearTimeout(timeout);
    var timeout=setTimeout(sendMessage,120000);
});

For a larger application, I would store last send time (and other information) in an Object that defines the connection. Have a regular process looks for connections with no activity, and handle appropriately.

You can wrap the the socket event into an observable, then just use the .debounce operator to only trigger the "please try sometime later" text after 2 minutes of inactivity (untested):

var adminResponses = Rx.Observable.fromEventPattern(
    function add (h) {
      socket.on('Admin Response',h);
    }
).debounce(120000); //120000 ms = 2 mins

var subscription = adminResponses.subscribe(
    function(msg) {
         /* show "please try sometime later" text */ 
    });
