### Release Notes

<details>
<summary>sindresorhus/pretty-ms</summary>

### [`v7.0.0`](https://togithub.com/sindresorhus/pretty-ms/releases/v7.0.0)

[Compare Source](https://togithub.com/sindresorhus/pretty-ms/compare/v6.0.1...v7.0.0)

##### Breaking

-   Always floor time instead of rounding up ([#&#8203;49](https://togithub.com/sindresorhus/pretty-ms/issues/49))  [`20cbdaf`](https://togithub.com/sindresorhus/pretty-ms/commit/20cbdaf)
    		It's probably not breaking to most users, but if you depend on the exact output, in for example, unit tests, the output might have changed slightly.
