Timer module. Functions also can be availble in the global context if you require globals module.
require("globals");
setTimeout(function(){ log("Test"); }, 2000);
var id = setTimeout(function(){ log("Test"); }, 2000);
...
clearTimeout(id);
setInterval(function(){ log("Test"); }, 2000);
var intervalId = setInterval(function(){ log("Test"); }, 2000);
...
clearInterval(intervalId)
OR
var timer = require("timer");
timer.setTimeout(function(){ log("Test"); }, 2000);
var id = timer.setTimeout(function(){ log("Test"); }, 2000);
...
timer.clearTimeout(id);
timer.setInterval(function(){ log("Test"); }, 2000);
var intervalId = timer.setInterval(function(){ log("Test"); }, 2000);
...
timer.clearInterval(intervalId)
