[SOLVED] - timedatectl Access denied - CentOS
forums.centos.org › viewtopicMar 27, 2014 · This immediately updated my timezone, and then the timedatectl command produced the output I was expecting. A coworker mentioned that I might have needed to stop ntp (in my case chronyd on RHEL7) temporarily; however, with this new soft-link in place the system was set to my expectation.

https://forums.centos.org/viewtopic.php?t=7334324.05.2020 · This is a CentOS 6 system and that does not use systemd nor any of the systemd-related utilities like timedatectl (actually practically any *ctl utils will not exist). You are also running a copy of CentOS 6 that is severely out of date. 6.7 is from 2015 so you are missing 5 years of security patches and enhancements.
