right-now 
Get the quickest, most high-resolution timestamp possible in node or the browser.
Instead of returning the date, right-now may use performance.now, Date.now, +new Date or process.hrtime to get a timestamp suitable for measuring intervals of time. Handy for both animation loops and precision benchmarking.
It's pretty small but saves me writing this boilerplate every time :)
Installation
npm install right-now
Usage
require('right-now')()
Returns a timestamp. In node, this uses process.hrtime. In the browser, support for the following is checked in this order:
performance.now()Date.now()+new Date
