Was playing around today and discovered an advanced menu that has a Jet Lag module and some other settings not usually seen. If you go to settings/system/about/SW Versions and tap repetedly on the SW Version (with number) after about 10 taps an advanced menu will appear at the top of the list. Inside you'll find a bunch of stuff including the Let Lag modules. Not sure if they work, or were just here for testing, but thought I'd share. There are some other settings and I'm not sure what they do, but maybe if others know or are inclined to find out you can let us know.
There is one for "Mark Logging File" that makes a cool sound when pressed, but other than that???
