> Easily format the time from node.js `process.hrtime`. Works with timescales ranging from weeks to nanoseconds.

Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.

## Install

Install with [npm](https://www.npmjs.com/):

```sh
$ npm install --save pretty-time
```

## Usage

```js
var pretty = require('pretty-time');

var start = process.hrtime();
var time = process.hrtime(start);
console.log(pretty(time));
//=> 3μs
```

## API

By default, when no time increment is given as the second argument, the closest timescale is used (e.g. _most granular without being less than zero_).

**Examples:**

```js
pretty([1200708, 795428088]);
//=> '2w'

pretty([800708, 795428088]);
//=> '1w'

pretty([400708, 795428088]);
//=> '5d'

pretty([70708, 795428088]);
//=> '20h'

pretty([12708, 795428088]);
//=> '4h'

pretty([3708, 795428088]);
//=> '1h'

pretty([208, 795428088]);
//=> '3m'

pretty([20, 795428088]);
//=> '21s'

pretty([0, 795428088]);
//=> '795ms'

pretty([0, 000428088]);
//=> '428μs'

pretty([0, 000000088]);
//=> '88ns'

pretty([0, 000000018]);
//=> '18ns'
```

### Minimum time increment

_(All of the following examples use `[6740, 795428088]` as the hrtime array.)_

This value is passed as the second argument and determines how granular to make the time.

**Examples**

```js
pretty(time, 'h');
//=> '2h'

pretty(time, 'm');
//=> '1h 52m'

pretty(time, 's');
//=> '1h 52m 21s'
```
