README.md demos as unix timestamps (since 1970) - but library is giving system uptime?

[hi2u]

Looking at the example in README.md - it looks like μs.now() should be returning the unix timestamp with microseconds... i.e. the number of microseconds elapsed since 1970.

The example shows:

// 1404398280599786
// { microseconds: 786, milliseconds: 599, seconds: 0, minutes: 38, hours: 14, days: 16254 }

...which is: Thursday, 3 July 2014 2:38:00 PM UTC, which makes sense, as that was around the time when the package was first published.

But when I run the same code shown in the examples I don't get the time since 1970, I get the operating system's uptime instead.

Here's my code, which I can't see being any different from README.md:

const μs = require('microseconds');
const now = μs.now();
console.log(`Now is: `, now);
console.log(`Parsed is: `, μs.parse(now));
console.log(`Parsed is: `, μs.parse(now).toString());

I get the output:

Now is:  436458757931.173
Parsed is:  { microseconds: 931,
  milliseconds: 757,
  seconds: 18,
  minutes: 14,
  hours: 1,
  days: 5,
  toString: [Function: toString] }
Parsed is:  5 days 1 hour 14 minutes 18 seconds 757 milliseconds 931 microseconds

I get the same result on both Windows (Node v12.14.1) and Linux (Node v10.17.0).
