Can use unjs/unstorage#136

[Barbapapazes]

Unfortunately, the created time can't be get from unstorage because it create a new file and return time from this new file.

[Barbapapazes]

After deeper investigations, it seems that unstorage won't help to solve this issue (adding the created at time). (unstorage will only help for the updatedAt meta. But because using this method, we can't get createdAt, I think it's not the best option.)

However, in the file src/runtime/markdown-parser/index.ts, at the line 57, there is a function called parseFrontMatter which return content and data. And because the parse method return a meta object, I think we could use it to get updatedAtand createdAt.
Unfortunaly, this could be a solution but git does not store timestamps. (https://stackoverflow.com/questions/62039244/does-git-store-the-file-creation-time).

So, there is no way to easily get creation date from a content file.

I also want to figure out how to get the created and updated time.

Checked out the starckoverflow you mention above, the answer provides an idea: each commit has timestamp

So my solution is searching the added commit and last updated commit associated with the specify file and get the timestamp

I write a server plugin for my Nuxt Content project BlogiNote

/**
 * add timestamp for markdown file
 */
import { execSync } from 'node:child_process'
// ...

export default defineNitroPlugin((nitroApp) => {
   // ...
    const firstCommitTime = execSync(`git log --diff-filter=A --format=%as -- ${filePath}`, { encoding: 'utf-8' }).trim();

   // ...
    const lastCommitTime = execSync(`git log -1 --format=%as -- ${filePath}`, { encoding: 'utf-8' }).trim();

 // ...
})

This won't be the precise time as the created and updated, and it works!

However I encouter another problem, this method just work fine locally.

When I deploy to Vercel, because the .git directory is not deployed, so it fail to get the commit time from git log
