I'm running CentOS 6 and I've noticed after Vesta installation that the server is set to UTC. I know how to change the timezone of a server, but I'm wondering if I can do it the manual way (i.e. /etc/localtime) or do I need to do it within the VestaCP? I checked the FAQ which addresses the timezone here, but it doesn't mention where in the CP you can make this change and I can't find it. So my question is can I just change the timezone manually without the use of the CP, without it harming anything to do with VestaCP?
Smaller side question, is it okay to perform YUM updates?
