community.general.timezone module – Configure timezone setting

Note

This module is part of the community.general collection (version 11.4.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.timezone.

Synopsis

  • This module configures the timezone setting, both of the system clock and of the hardware clock. If you want to set up the NTP, use ansible.builtin.service module.

  • It is recommended to restart crond after changing the timezone, otherwise the jobs may run at the wrong time.

  • Several different tools are used depending on the OS/Distribution involved. For Linux it can use timedatectl or edit /etc/sysconfig/clock or /etc/timezone and hwclock. On SmartOS, sm-set-timezone, for macOS, systemsetup, for BSD, /etc/localtime is modified. On AIX, chtz is used.

  • Make sure that the zoneinfo files are installed with the appropriate OS package, like tzdata (usually always installed, when not using a minimal installation like Alpine Linux).

  • Windows and HPUX are not supported, please let us know if you find any other OS/distro in which this fails.

Can run in check_mode and return changed status prediction without modifying target.

diff_mode

Support: full

Returns details on what has changed (or possibly needs changing in check_mode), when in diff mode.

Notes

Note

  • On Ubuntu 24.04 and Debian 13 (Trixie), the util-linux-extra package is required to provide the hwclock command.

  • On SmartOS the sm-set-timezone utility (part of the smtools package) is required to set the zone timezone.

  • On AIX only Olson/tz database timezones are usable (POSIX is not supported). An OS reboot is also required on AIX for the new timezone setting to take effect. Note that AIX 6.1+ is needed (OS level 61 or newer).

Examples

- name: Set timezone to Asia/Tokyo
  become: true

    name: Asia/Tokyo
