I have an FC/Redhat/CentOS box and I would like to change my time zone for the entire system and all users to UTC; date –u seems to only changes the individual users zone.  And, since I don’t have a GUI on my box I can not use system-config-time.  So, I was thinking /etc/localtime should be a simlink to the time zone in /usr/share/zoneinformation rite?  I can just change that with a new symlink, rite? But the file I have in /etc/localtime is a small binary file and that made me nervous.  Then I thought, setup, how much more basic could I get!  But it does not have a time zone option, only Authentication and System Services.

Any suggestions?
