ansible.builtin.strftime filter – date formating

Note

This filter plugin is part of ansible-core and included in all Ansible installations. In most cases, you can use the short plugin name strftime. However, we recommend you use the Fully Qualified Collection Name (FQCN) ansible.builtin.strftime for easy linking to the plugin documentation and to avoid conflicting with other collections that may have the same filter plugin name.
