Unable to set custom commit date using GitHub API

Body

Hi, I am encountering an issue while trying to set a custom commit date using the GitHub API. Despite providing the correct committer object with a specified date field, the commit date is always set to the current date and time when the request is made.

Doc link: https://docs.github.com/en/rest/repos/contents?apiVersion=2022-11-28

Code example:

const commitDataObj = {
    message: "Commit message",
    content: "base64-encoded-content",
    sha: "the-sha-of-the-file-being-updated",
    committer: {
        name: "devpotatoes",
        email: "devpotatoes@gmail.com",
        date: "2020-01-01T00:00:00Z"
    }
};

fetch("https://api.github.com/repos/devpotatoes/repositoryName/contents/path/to/file", {
    method: "PUT",
    headers: {
        "Accept": "application/vnd.github+json",
        "Authorization": "Bearer PAT",
        "X-GitHub-Api-Version": githubApiVersion
    },
    body: JSON.stringify(commitDataObj)
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error(error));

I tried other date format but it does not resolve the problem.

Any guidance or assistance in resolving this issue would be greatly appreciated.

GitHub API currently does not support setting a custom commit date directly through the committer.date field when making a commit via the API. you gotta try other way. try using local git client to commit with the date you want

Hmm I see, it's quite strange to document something that isn't even implemented yet...

The Git Data API gives you more low-level control over the Git objects and allows setting custom commit dates.

Hope this helps! Let me know if you have any other questions.

Ohh yes indeed, I hadn't heard of it, but I've managed to find a few pieces of documentation that talk about being able to specify the commit date, I'll try to implement that. Thank you !
