relative-microtime
This module returns the number of microseconds elapsed since January 1,
1970 00:00:00 UTC.
Note: The returned number of microseconds are locked relative to a
specific time and is therefore not subject to clock drift. This is
contrary to how Date.now() operates, whos return value (in
milliseconds) is always based on the system clock.
Installation
npm install relative-microtime --save
Usage
const timer = require('relative-microtime')()
const milli = Date.now()
const micro = timer()
console.log(milli) // 1537446194859
console.log(micro) // 1537446194859132
Gotcha

will not influence the returned timer.
