Knoppix 8.1 USB-stick installation

[Karibu]

I entered UTC in /etc/adjtime and set the time zone again to America/Vancouver.
After reboot /etc/adjtime was still ok (UTC) but /etc/timezone was again "localtime".
What to do?

[philo]

BIOS time (hardware clock) --> UTC

/etc/adjtime --> UTC [instaead of LOCAL]

/etc/timezone ---> America/Vancouver

and maybe in :
/media/sd__/boot/syslinux/syslinux.cfg
LABEL knoppix LABEL knoppix64, add inside APPEND:

--> tz=America/Vancouver
