How to Use Date, Time, and Timestamp in Ansible Playbook.

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 in Ansible Playbook

"ansible_date_time": {
        "date": "2022-05-18",
        "day": "18",
        "epoch": "1652887408",
        "epoch_int": "1652887408",
        "hour": "15",
        "iso8601": "2022-05-18T15:23:28Z",
        "iso8601_basic": "20220518T152328995863",
        "iso8601_basic_short": "20220518T152328",
        "iso8601_micro": "2022-05-18T15:23:28.995863Z",
        "minute": "23",
        "month": "05",
        "second": "28",
        "time": "15:23:28",
        "tz": "UTC",
        "tz_dst": "UTC",
        "tz_offset": "+0000",
        "weekday": "Wednesday",
        "weekday_number": "3",
        "weeknumber": "20",
        "year": "2022"

The good news is that Ansible provides the ansible_date_time variable that already has out-of-the-box information about date and time. This dictionary has a lot of keys and values that should be self-explicative and also enable a lot of use-cases. For example inside the Ansible Playbook, on debug messages, on output and input files. The only drawback is that the Ansible ansible_date_time variable requires Ansible Facts enabled, so the gather_facts: true statement on your Ansible Playbook.

demo

Are you ready to make your hands dirty? Let’s jump into a quick live demo of Using Date, Time, and Timestamp in the Ansible Playbook. I’m going to share with you how to display the full ansible_date_time and the ISO8601 format.

code

---
- name: date and time demo
  hosts: all
  gather_facts: true
  tasks:
    - name: date and time
      ansible.builtin.debug:
        var: ansible_date_time
    - name: ISO8601
      ansible.builtin.debug:
        var: ansible_date_time.iso8601

execution

$ ansible-playbook -i virtualmachines/demo/inventory variables/datetime_fact.yml
