The last updated time displayed on the page is always Thursday, January 1, 1970 08:00:00

The time obtained using the "git log" command is correct.

The time of all pages is this, whether it is on the local "vitepress dev docs" or on GithubPage.
why is this happening？
The version number of vitepress is 1.0.1.
I can't find where is the function to get the time.

Please verify if this is returning correct timestamp:

git log -1 --pretty="%ai" "path/to/your/file.md"

thank you for your reply! I found the reason!
I added "lastUpdated: true" to the frontmatter of the markdown file.
I create another file without adding this key-value pair. After submitting, the correct time is displayed on the page.
Moreover, the last updated timestamp obtained using "useData" is correct.
It is because "lastUpdated: true" is added to frontmatter that the time on the page is displayed incorrectly.
Is this a bug? It seems to me that the description in the documentation is not accurate:
