Hello.
I have a few questions for you.

Does dietpi interface support to change ntp server ?
Why timedatectl vs chrony ?

and how could I solve this error ?

dietpi@pi4:~ $ sudo timedatectl status
Failed to create bus connection: No such file or directory

Thanks

Hi,

Usually time sync is done during boot and on daily basis. NTP server can be changed via dietpi-config.

dietpi-config > 8 : Network Options: Misc > NTP Mirror

To run a time sync you can do systemctl start systemd-timesyncd or /boot/dietpi/func/run_ntpd

Thanks for the answer.

I update the NTP Mirror base on your info.
However, I still have a error message with

root@pi4:/# timedatectl
Failed to create bus connection: No such file or directory

Pls use date to check current time or systemctl start systemd-timesyncd to sync time with an NTP server. By default dbus is not active/installed

timedatectl status and systemctl status systemd-timesyncd was the same thing for me.
Thank to point me out the correct way.

usually systemctl status systemd-timesyncd should display the status of the time sync service. In normal circumstances status is inactive

root@DietPiProd:~# systemctl status systemd-timesyncd
● systemd-timesyncd.service - Network Time Synchronization
   Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; disabled; vendor preset: enabled)
  Drop-In: /lib/systemd/system/systemd-timesyncd.service.d
           └─disable-with-time-daemon.conf
   Active: inactive (dead)
     Docs: man:systemd-timesyncd.service(8)

As well you will see a couple of lines from the log. To display the full log, just run journalctl -u systemd-timesyncd

root@DietPiProd:~# journalctl -u systemd-timesyncd
