issue: create_date Variable

This addresses an issue where the create_date variable is showing as Unix
timestamp instead of formatted date. This was due to a typo introduced in
commit `8623ed60` where the `$format` argument was forgotten for
`Format::datetime()` in the `FormattedLocalDate::getVar()` method.
