| If your are still not keen to create your very own TZ string you can cheat by taking a peek in the (binary) zoneinfo files of the tzdata.tcz extension. Please note that in the following steps (using London as an example) the extension gets merely downloaded (to the home directory), extracted and right away removed again. So nothing remains afterwards. Let's face it, you probably need to find out your local TZ definition only a few times in your life (e.g. when you move or your daylight saving timeframe changes): | If your are still not keen to create your very own TZ string you can cheat by taking a peek in the (binary) zoneinfo files of the tzdata.tcz extension.
