You are right of course - I should remember to read my own code properly. 
However, /etc/localtime is usually not a symlink. If you are missing 
/etc/timezone, you can also try /usr/local/etc/timezone (that's the default 
location where the timezone library installs itself on a system that does not 
have it per default).

I just checked my Android phone (a Galaxy Nexus with Android 4.1): I can't 
find the time zone info there - it is not in any of the numerous etc 
directories or in an environment variable, you have to use the Android Java 
API or call "getprop persist.sys.timezone" (with QProcess, the output will be 
the time zone in "Europe/Berlin" format).

I'll set myself a reminder to check my Mac in the evening.
