[CentOS] centos7: ntpd not started on boot

Hi,

I have got problems with the ntp daemon.

It is enabled in systemd but is not started on boot.

# systemctl status ntpd
● ntpd.service - Network Time Service
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor
preset: disabled)
   Active: inactive (dead)

Starting manually works
# systemctl start ntpd
# systemctl status ntpd
● ntpd.service - Network Time Service
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor
preset: disabled)
   Active: active (running) since Fri 2016-07-29 10:29:45 CEST; 3s ago

I see nothing ntpd related /var/log/messages or journactl during the
boot phase. Seems like no attempt is made to start it at all.

Is there something that need to be done besides enabling it with systemctl?

Regards
