Please note that showLastUpdateTime does not work properly if the build is run with the default GitHub Actions configuration

It took me some time to diagnose this, so perhaps this post can help others save some time.

The problem is that the default depth for the actions/checkout@v4 action is 1 (latest commit only), and in this case git log cannot retrieve the dates of previous commits; instead it returns the date of the latest commit (the only one cloned), for all files, and all documentation pages appear to be updated at the same time.

The solution is to clone the repo with the full history:

      - name: Checkout
        # https://github.com/actions/checkout
        uses: actions/checkout@v4
        with:
          # Get the full history, required to compute lastUpdatedAt
          fetch-depth: 0

It would be nice to have this info in the documentation page:

• https://docusaurus.io/docs/api/plugins/@docusaurus/plugin-content-docs#showLastUpdateTime

Welcoming PRs :)

I took the liberty of opening a PR #9784

Thank you @mjec, I planned to do it during the next days, but your PR is welcome.

I would have also added the GitHub example, after the table, since the explanation inside the table might not be noticed.

Thanks

I've added this to our GitHub Actions docs recently too but it doesn't harm to add it in another extra place.
