Requirement: To get datetimestamp in the main page of the dbt docs site , so that we know when it was last refreshed

Code:

Have created a macro and the macro is been called in the overview.md

macro

{% macro get_date_test() %}
    {{ return((date_trunc('day', current_timestamp()) | string).replace('-', '')) }}
{% endmacro %}

under the dbt folder docs>overview.md

{% docs __overview__ %}

This documentation was created-on:: {{ get_date_test }}

{% enddocs %}

dbt_project.yml

docs-paths: ["docs"]

dbt docs doesn’t show the date yet

I tried changing to calling as below , it threw an error as dbt couldn’t recognize the macro

{{ get_date_test() }}
