I am configuring dnf-automatic to automatically install security updates on some low priority test boxes. Eventually I want to the updates to run every Sunday morning around 4-5AM, but for testing purposes I've configured the boxes to kick off the update Wed afternoons at 14:xx and minimised any randomisation for now. After being started, the first update does run at it's schedule time, but if I then look at the timer status in systemd, the next schedule time of running is 6am the next day. I understand this is the time that dnf-automatic executes by default which may bear some relation, but I don't see where this is referenced in my config:

● dnf-automatic-install.timer - dnf-automatic-install timer
   Loaded: loaded (/usr/lib/systemd/system/dnf-automatic-install.timer; enabled; vendor preset: disabled)
  Drop-In: /etc/systemd/system/dnf-automatic-install.timer.d
           └─override.conf
   Active: active (waiting) since Wed 2023-12-06 14:45:31 GMT; 20min ago
  **Trigger: Thu 2023-12-07 06:00:02 GMT; 14h left**

Dec 06 14:45:31 dcbutlpocglog5.zonalconnect.local systemd[1]: Started dnf-automatic-install timer.

Relevant config files as follows:

[root@dcbutlpocglog5 ~]# cat /etc/systemd/system/dnf-automatic-install.timer.d/override.conf
[Unit]
Description=dnf-automatic-install timer
# See comment in dnf-makecache.service
ConditionPathExists=!/run/ostree-booted
Wants=network-online.target

[Timer]
OnCalendar=Wed 14:51
RandomizedDelaySec=5s
Persistent=true


[Install]
WantedBy=timers.target


[root@dcbutlpocglog5 ~]# cat /etc/dnf/automatic.conf
[commands]
upgrade_type = security


[emitters]
emit_via = motd


[install]
upgrade_requirements_on_install = yes
download_updates = yes
apply_updates = yes
gpgcheck = 1
emit_via = motd
random_sleep = 5
reboot = yes

Can anybody tell me why this is happening please, and help me prevent the extra updates running outside of what is configured?

Thanks

Fix found, it seems SystemD timers are additive and an additional blank "OnCalendar=" parameter was needed in front of my own to clear the normal one:

[Timer]
OnCalendar=
OnCalendar=Wed 14:51
RandomizedDelaySec=5s
Persistent=true

Result:

[root@dcbutlpocglog5 ~]# systemctl status dnf-automatic-install.timer
● dnf-automatic-install.timer - dnf-automatic-install timer
Loaded: loaded (/usr/lib/systemd/system/dnf-automatic-install.timer; enabled; vendor preset: disabled)
Drop-In: /etc/systemd/system/dnf-automatic-install.timer.d
└─override.conf
Active: active (waiting) since Wed 2023-12-06 14:45:31 GMT; 20h ago
