Monotonically increasing time in JavaScript?

Question

What’s the best way to get monotonically increasing time in JavaScript? I’m hoping for something like Java’s System.nanoTime().

Date() obvi

Answer 1

Firefox provides "delay" argument for setTimeout... this is the one of ways to implement monotonically increased time counter.

var time = 0;

setTimeout(function x(actualLateness) {
  setTimeout(x, 0);
  time += actualLateness;
}, 0);
