Clear Linux* OS uses the systemd-timesyncd.service daemon to synchronize time.

This guide describes how to reset the time in your Clear Linux OS system when the default NTP servers cannot be reached.

  1. Install the sysadmin-basic bundle.

    sudo swupd bundle-add sysadmin-basic
  2. Set your time zone. This example uses Los Angeles.

    timedatectl set-timezone America/Los_Angeles


    To see a list of time zones, use the command: timedatectl list-timezones | grep <locale>

  3. Create a /etc/systemd/ directory.

    sudo mkdir -p /etc/systemd/
  4. Create a new file named /etc/systemd/timesyncd.conf and enter the following text.

    NTP=<Preferred Server>
    FallbackNTP=<backup server 1> <backup server 2>
  5. Enable the systemd-timesyncd service.

    timedatectl set-ntp true


To check the service status, use the timedatectl status command.

To restart the timesyncd daemon, enter systemctl restart systemd-timesyncd into your terminal emulator.

Congratulations! You successfully set up the time in your Clear Linux OS system.
