This question has already been answered for the browser here, but window.performance.now() is obviously not available in Node.js. Some applications need a steady clock, i.e., a clock that monotonically increases through time, not subject to system clock drifts. For instance, Java has System.nanoTime() and C++ has std::chrono::steady_clock. Is such clock available in Node.js? Answer Turns out the equivalent in Node.js
