How do I get the server uptime in Node.js?

Question

How do I get a server uptime in Node.js so I can output it by a command like;

if(commandCheck("/uptime")){
  Give server uptime;
}

Now I don't know how to calculate the uptime from the server's startup.

You can use process.uptime(). Just call that to get the number of seconds since node was started.

function format(seconds){
  function pad(s){
    return (s < 10 ? '0' : '') + s;
  }
  var hours = Math.floor(seconds / (60*60));
  var minutes = Math.floor(seconds % (60*60) / 60);
  var seconds = Math.floor(seconds % 60);

  return pad(hours) + ':' + pad(minutes) + ':' + pad(seconds);
}

var uptime = process.uptime();
console.log(format(uptime));
