Time management in self hosted engine vm

Hello, I have a self hosted engine HCI environment that was born in 4.0.5 through the ansible/gdeploy mechanism and then gradually updated to 4.1.7 Now the engine and host are at CentOS 7.4 level. Inside the gdeploy jobs the engine vm was installed through the appliance at the 4.0.5 time. I see in web admin gui that hw clock of engine vm is configured as UTC (so far so good) and the same is inside the OS. And I would like to change it to UTC+1 like the 3 hosts I also see that neither chronyd nor ntpd are installed on engine vm. Can I fix the situation the normal os level way: - timedatectl set-timezone "Europe/Rome" - install and configure chronyd or better not to configure time sync in engine vm? Thanks, Gianluca

Hi, - I would not recommend changing the hw clock timezone - The OS timezone can be freely changed afaik (using any tool possible) - I do not see how enabling time sync would break anything either My development machines run engine using CET timezone and hosts using UTC. I have never seen any issues.. Martin Sivak On Tue, Nov 28, 2017 at 4:43 PM, Gianluca Cecchi <gianluca.cecchi@gmail.com> wrote:
