How to use Date, Time, and Timestamp without Facts in Ansible Playbook.

A quick and dirty workaround using the date command-line utility. I’m going to show you a live demo and some simple Ansible code. I’m Luca Berton and welcome to today’s episode of Ansible Pilot.

Using Date, Time, and Timestamp without Facts in Ansible Playbook

Date and time

ISO8601

How to Use the Date, Time, and Timestamp in Ansible Playbook. The ansible_data_time fact is an amazing resource but sometimes you can’t have it or you don’t want to use the date and time of the remote host. These solutions enable you to print the Date and Time and ISO8601 format. I ended up after carefully reading the date man page. Unfortunately not all the platforms support the --iso-8601 parameter so you need to build it manually the format by yourself (for example in macOS operating system).
