But if you export VAR=value at the time you log in, it will be
propagated to all processes you run during that session. So you
need to stick that line into some file that your login environment
runs before it starts launching other processes. What file that is
depends on what desktop/window manager you run (I run openbox so
I'm probably no help to gnome/kde/unity users).
It would still be better to set the whole system's time zone rather
than patching your login environment, though. For instance, it would
be nice if timestamps in log files were in the right time zone.
