Please use @Frank's one line solution:

```
new Date(SECONDS * 1000).toISOString().substring(11, 16)
```

If SECONDS<3600 and if you want to show only MM:SS then use below code:

```
new Date(SECONDS * 1000).toISOString().substring(14, 19)
```

It is by far the best solution.

Old answer:

Use the `Moment.js` library.
