Render clock in post

Hi I came across this repo while looking for svelte blog examples with mdsvex. I am not sure what your goal was but the following renders for me:

_**src/content/post-one.md**_
```
---
title: Blog Post One
description: This is the first blog post.
---

<script>
  import Clock from '$lib/Clock.svelte'
</script>

# Heading

Words and stuff and things and junk.

<Clock/>

```
