The chronyd.service was enabled and started manually and after couple minutes it exits like an orderly shutdown.

The chronyd.service status shows an orderly shutdown and the service in an inactive state.

Both chronyd.service and yast-timesync.timer are enabled on systemd:

# systemctl show chronyd.service | grep UnitFileState

# systemctl show yast-timesync.timer | grep UnitFileState

The yast-timesync.timer is running:

# systemctl status yast-timesync.timer 
● yast-timesync.timer
   Loaded: loaded (/etc/systemd/system/yast-timesync.timer; enabled; vendor pre>

Sep 15 14:47:16 localhost systemd[1]: Started yast-timesync.timer.



systemctl stop yast-timesync.timer
systemctl disable yast-timesync.timer
systemctl restart chronyd.service

yast ntp-client and set Now and on Boot


The root cause is both yast-timesync.timer and chronyd.service are active at the same time and yast-timesync.service (triggered by yast-timesync.timer) runs a single instance of chronyd to update the system time and then exit. This shuts down the chronyd.service.

Additional Information

The yast-timesync.service enabled and gets triggered by yast-timesync.timer every 5 minutes. It runs chronyd in single-shot mode (-q) to set the system time once and then exits. yast-timesync.service conflicts with chronyd.service, because only one instance of chronyd can run at any given time.
