Knoppix 8.1 USB-stick installation

[Karibu]

I found syslinux.cfg in >Root >KNOPPIX >boot and added
inside APPEND: -->tz=America/Vancouver

Now, in window under ---> Preferences ---> Time and Date the line 'Time zone' is filled in correctly (America/Vancouver) and the line 'Configuration' is filled in correctly (Keep synchronized with Internet servers) as well.
I still don't get the PST (Pacific Standard Time) though. Only if I switch the configuration back and forth between 'Manual' and '...synchronized...' then, after a few minutes, the PST is shown....

What else is missing?

What else is missing?

The ntp package?
