This paragraph of documentation is very similar to the documentation
on the Olson timezone database:

ftp://ftp.iana.org/tz/data/Theory

    Names normally have the form AREA/LOCATION, where AREA is the name
    of a continent or ocean, and LOCATION is the name of a specific
    location within that region.  North and South America share the same
    area, 'America'.  Typical names are 'Africa/Cairo', 'America/New_York',
    and 'Pacific/Honolulu'.

This strongly indicates that zoneinfo-style-world-list just refers to
timezone names as listed in that database.

Armed with this knowledge, you can try using "Etc/UTC", and browse the
database for names of other time zones.
