You can set the timezone independently for each process on a UNIX system 
through the TZ environment variable.  For example,

% date
Mon Nov  8 10:10:08 CST 2010
%  TZ=PST8PDT date
Mon Nov  8 08:10:10 PST 2010
% TZ=Paris date
Mon Nov  8 16:10:14 Paris 2010

This syntax applies the environment variable only to the command 
following it.  It does not set the value into the environment of the 
shell where you typed the command.

You could simply put the desired zone name (e.g., London) into the TZ 
variable and change the "date" command above to your front-end command 
(with whatever options you want).  Of course, you could also have a 
small shell script that sets the environment variable and then runs the 
front-end to reduce typing.  (To see a list of available timezone names, 
look in /usr/share/zoneinfo and its subdirectories.)

By doing it this way, the environment variable change affects *only* the 
front-end startup and all other processes on the system continue using 
the normal time zone.

Note that this technique works for any environment variable, not just TZ.
