Setting age=0 on a tidy resource does not remove all files

Puppet Version: any
Puppet Server Version: n/a
OS Name/Version: n/a

The documentation for the age parameter for the tidy type states:

Tidy files whose age is equal to or greater than the specified time. You can choose seconds, minutes, hours, days, or weeks by specifying the first letter of any of those words (for example, ‘1w’ represents one week).

Docs: https://puppet.com/docs/puppet/7.7/types/tidy.html#tidy-attribute-age

Specifying 0 will remove all files.

Desired Behavior:

Setting age=0 removes all files

Actual Behavior:

Setting age=0 requires the target file to be at least 1 second old.

This was discovered when writing integration tests for the puppet resource subcommand (PUP-11074).

Relevant code: https://github.com/puppetlabs/puppet/blob/b91e53a38cb4671d4de9078837c05931c69121f9/lib/puppet/type/tidy.rb#L147

    def tidy?(path, stat)

      # If the file's older than we allow, we should get rid of it.

      (Time.now.to_i - stat.send(resource[:type]).to_i) > value

    end

Note that the greater than or equal comparison is respected for the size parameter:

    def tidy?(path, stat)

      stat.size >= value

    end
