Environment: KVM CentOS 7.2 Minimal installation.

I am trying to sync the time with an NTP server in my network.

My Proxmox-Host (Debian based) is able to do this by enabling systemd-timesyncdcombined with a configuration file /etc/systemd/timesyncd.conf.

The CentOS 7.2 installation just got systemd-timedated and with the command timedatectl NTP is just available if I install the package chronyd or ntp.

Question: Is the NTP-Client-Part of systemd (in Proxmox timesyncd) not included in CentOS / RedHat 7 and I definitely need chronyd or ntpd?

  • if I understand your question, yes, you must install the chrony or ntp rpm for time sync to work. – meuh Jun 1 '16 at 14:13
  • So the ntp-component of timedated is bot available at CentOS? – Markus Jun 1 '16 at 15:21

Yes, it appears that RedHat chose to compile systemd without systemd-timesyncd feature.

    Is there an explanation for this, some what, absurd decision ? – dotvotdot Apr 9 '18 at 13:45
  • seems like chronyd is used by default – Justin Cameron Oct 12 '18 at 3:36
