date time zone - CentOS
forums.centos.org › viewtopicOct 15, 2019 · 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 You are also running a copy of CentOS 6 that is severely out of date. 6.7 is from 2015 so you are missing 5 years of security patches and enhancements.
