## Retrieve Block Date

### Instructions

Using Node.js, create and exports a function `retrieveBlockDate()` that takes as input the height of a block and returns the date of this block. The date must be a `date` javascript object. The script must connect to a local node available on `localhost:18443`, with the user `leeloo` and the password `multipass`.

### Usage

```js
retrieveBlockDate(1881467) // Expected : 2020-11-05T20:18:48.000Z
```
