Setting timezone globally for OpenIndiana Hipster?

What is the correct way of setting the timezone (CentralEuropeanTime... or now rather CET with Daylight Savings Time) on the latest version of OpenIndiana Hipster? I've tried a changing a few things in **/etc/**, but I'm obviously not doing it right, since my clock remains at Universal-time (UTC). A similar question (for Solaris?) suggested a command, but this isn't available on OpenIndiana - nor is the package it was supposed to be in. I got a multi-boot system, so I want to keep the system clock in Universal (UTC), rather than in local-time (CET). So what *exactly* should I do - where and how? (I guess the easiest would be to just make, edit or link a file in **/etc**, or something if possible...)
