That part of the documentation is correct. The -s flag skips the UTC question. 

I was referring to:

    It is possible to short-circuit the menu system by specifying the
    location of a zoneinfo_file or the name of the zoneinfo_name on the
    command line; this is intended mainly for pre-configured installation
    scripts or people who know which zoneinfo they want to install.

I provided the location of the zoneinfo file and still the menu pops up. When I read "possible to short-circuit the menu system", I interpret that as that the menu won't pop up.
