Continuing with your suggestion, I encountered
 
Zoneinfo Style World List 
   Alist of zoneinfo-style time zones and places for ‘world-clock’.
   Each element has the form (TIMEZONE LABEL).
   TIMEZONE should be a string of the form AREA/LOCATION.

Would users prefer seeing AREA/LOCATION or just LOCATION?
Area is the name of a region -- a continent or ocean.
