Despite the fact that America/Edmonton was explicitely picked up
from a menu an installed system ended up in UTC time zone anyway.
The plaform was Alpha/UX.
This may have something to do with a fact that a hardware clock runs
in UTC time and which was selected as well.
It works for me using 6.2 on one of our test lab machines; unfortunately we
don't have a UX ...
