optionally enabled. adds the 'timezone' option to config, which takes a valid timezone (i.e. Europe/Vienna) to set in the container.
if nothing is selected, then it will show as 'container managed' in GUI, and nothing will be done. if set to 'host', the /etc/localtime symlink from the host node will be cached and set in the container rootfs.
