Mageia-8/9 has a bug (27195) that does not allow you to set and apply automatic time synchronization via NTP (Mageia Control Center, drakclock). The rpm package located here fixes this problem. After installation, the following commands are executed automatically (%post):
systemctl stop chronyd ntpd; systemctl disable chronyd ntpd
cd /usr/libexec; patch -Ni drakclock.patch
if [[ -f /etc/chrony.conf ]]; then
cat > /etc/chrony.conf << EOF

The program is designed for active monitoring of the state of ntpd.service and chronyd.service services and is intended for configuring the "NTP" function in drakclock (Mageia Linux x86_64). When drakclock_test is started, it displays the full state of ntpd and chronyd (active/inactive, enabled/disabled) IN REAL TIME. This allows you to test drakclock in various ways: install/delete ntp/chrony packages, manage NTP from drakclock and immediately monitor the status.
