- plugin/transformer

This plugin determines the created, modified, and published dates for a document using three potential data sources: frontmatter metadata, Git history, and the filesystem. See [[authoring content#Syntax]] for more information.

[!note]
For information on how to add, remove or configure plugins, see the [[configuration#Plugins|Configuration]] page.

This plugin accepts the following configuration options:

• priority: The data sources to consult for date information. Highest priority first. Possible values are "frontmatter", "git", and "filesystem". Defaults to ["frontmatter", "git", "filesystem"].

[!warning]
If you rely on git for dates, make sure defaultDateType is set to modified in quartz.config.ts.

Depending on how you [[hosting|host]] your Quartz, the filesystem dates of your local files may not match the final dates. In these cases, it may be better to use git or frontmatter to guarantee correct dates.
